A 1. 0 g coffee filter dropped from a height of 0. 5 m reaches a terminal speed of 1 m/s. How much ke approximately did the air molecules gain from the falling coffee filter?.

Answers

Answer 1

the air molecules gained approximately 0.5 J of energy from the falling coffee filter.

Energy possessed by air molecules due to the falling coffee filter is calculated as follows:

The potential energy of the coffee filter when it was dropped can be calculated by the formula;

Potential energy = mgh

where; m = mass of coffee filter = 1.0 gh = height from which the coffee filter was dropped = 0.5 g = acceleration due to gravity = 9.81m/s²Substituting the given values in the above equation,

Potential energy = 1.0 x 0.5 x 9.81= 4.905 J

When the coffee filter reaches a terminal speed, its kinetic energy is equal to its potential energy.

Thus;

Kinetic energy = 4.905 J

The energy gained by the air molecules from the falling coffee filter is approximately equal to the kinetic energy of the filter, i.e.,

Kinetic energy = 4.905 J ≈ 0.5 J (approx)

Therefore, the air molecules gained approximately 0.5 J of energy from the falling coffee filter.

The seed planted at extreme cold or in the region of frozen ice do not germinate, why?​

Answers

Answer:

yes

The the seed planted at Extreme cold or in the region of frozen I did not germinate because the amount of moisture of the seed is too high which results in lack of air of the sea in the frozen ice

In fact, a soil temperature below 50°F might be problematic for many garden plants. Seeds will quickly absorb water at 40°C, but they won't begin to grow. This presents a risk for rot and disease, which may cause damping-off or subpar growth.

What is germination of seed?

The formation of the seedling is the consequence of germination, which is often the growth of a plant inside a seed. It is also the process of the seed's metabolic machinery being reactivated, which causes the radicle and plumule to emerge. A vascular plant's seed is a little bundle that develops in a fruit or cone as the result of the union of the male and female reproductive cells.

Given the need for particular internal or external stimuli to resume growth, dormant seeds are viable seeds that do not germinate. When the right circumstances are present, the seed starts to germinate and the embryo starts to grow again, eventually becoming a seedling.

Explain the stages of complete and incomplete metamorphosis, provide examples for each. (Counts 20% of your lesson grade.)

Answers

Metamorphosis refers to the process of development and change in the body form of certain animals as they grow from juveniles to adults.

Explain the types of metamorphosis?

Metamorphosis is classified into two types: complete and incomplete.

1. Complete metamorphosis:

Complete metamorphosis is a developmental process in which the juvenile form of an animal goes through four distinct stages: egg, larva, pupa, and adult. In this type of metamorphosis, the juvenile form looks completely different from the adult form in terms of appearance, behavior, and habitat.

Animals that undergo complete metamorphosis include:

a) Butterflies and moths: The egg hatches into a caterpillar (larva) that feeds and grows rapidly. The larva then forms a pupa or chrysalis, where the body undergoes a complete transformation into an adult butterfly or moth.

b) Flies: The egg hatches into a worm-like maggot (larva) that feeds and grows. The maggot then transforms into a pupa, and finally, an adult fly emerges.

c) Beetles: The egg hatches into a grub (larva) that feeds and grows. The grub then transforms into a pupa, and finally, an adult beetle emerges.

Incomplete metamorphosis:

Incomplete metamorphosis is a developmental process in which the juvenile form (nymph) of an animal resembles the adult in appearance and habitat, but is smaller and lacks wings. The nymph goes through several stages of growth and molting before reaching adult form.

Animals that undergo incomplete metamorphosis include:

a) Grasshoppers: The egg hatches into a nymph that resembles the adult grasshopper but lacks wings. The nymph goes through several molts and growth stages before developing wings and reaching the adult stage.

b) Cockroaches: The egg hatches into a nymph that resembles the adult cockroach but lacks wings. The nymph goes through several molts and growth stages before developing wings and reaching the adult stage.

c) Dragonflies: The egg hatches into a nymph that lives in water and resembles the adult dragonfly but lacks wings. The nymph goes through several molts and growth stages before developing wings and emerging from the water as an adult dragonfly.

Answers

At the instant shown, the six scenarios can be ranked in terms of the magnitude of current in the light bulb as follows:

1) Scenario 1 - Here, the battery is directly connected to the light bulb without any other resistors in the circuit. Therefore, the current flowing through the bulb will be the maximum among all the scenarios.

2) Scenario 3 - In this case, the battery is connected to the light bulb through a resistor. However, the resistance is less compared to other scenarios, so the current will be higher than in other cases.

3) Scenario 4 - Here, the battery is connected to the light bulb through a higher resistance compared to scenario 3. This will result in a lesser current in the bulb.

4) Scenario 5 - In this scenario, the battery is connected to the light bulb through a much higher resistance than in the previous two scenarios. Therefore, the current flowing through the bulb will be lower.

5) Scenario 6 - Here, the battery is connected to the circuit in such a way that the current will bypass the light bulb. Therefore, the bulb will not light up and the current flowing through it will be zero.

6) Scenario 2 - This scenario is similar to scenario 6 where the switch is open, so the circuit is not complete, and hence there will be no current flowing through the light bulb.

(ii) (a) a 2.80 cm high insect is 1.30 m from a 135 mm focal length lens. where is the image, how high is it, and what type is it? (b) what if / 135 mm?

Answers

When a 2.80 cm high insect is positioned 1.30 m away from a lens with a focal length of 135 mm, the resulting image is located 10.07 cm from the lens, has a height of 0.22 cm, and is a virtual and upright image.

(ii) (a) Given:

Object height (h₁) = 2.80 cm

Object distance (u₁) = 1.30 m = 130 cm

Focal length of the lens (f₁) = 135 mm = 13.5 cm

Using the lens formula: 1/f = 1/v - 1/u, where f is the focal length, v is the image distance, and u is the object distance.

Substituting the given values:

1/13.5 = 1/v - 1/130

Solving for v, the image distance formed by the lens:

1/v = 1/13.5 + 1/130

1/v = (10 + 1)/135

1/v = 11/135

v = 135/11 ≈ 12.27 cm

M₁ = -v/u₁

M₁ = -(12.27/130)

M₁ ≈ -0.094

formula: h₂ = |M₁| * h₁

h₂ = |-0.094| * 2.80

h₂ ≈ 0.263 cm

The height of the image (h₂) is approximately 0.263 cm.

Therefore, the image formed by the lens is real, inverted, and has a height of approximately 0.263 cm. It is located at a distance of approximately 12.27 cm from the lens

(ii) (b) If the focal length of the lens is changed to 135 mm (0.135 m), we can repeat the calculations using the new focal length.

Object height (h₁) = 2.80 cm

Object distance (u₁) = 1.30 m = 130 cm

Focal length of the lens (f₁) = 0.135 m = 13.5 cm

1/13.5 = 1/v - 1/130

Solving for v, the image distance formed by the lens:

1/v = 1/13.5 + 1/130

1/v = (10 + 1)/135

1/v = 11/135

v = 135/11 ≈ 12.27 cm

The image distance (v) and the magnification (M) remain the same as in part (a) because the object distance (u₁) and the focal length (f₁) are unchanged. Therefore, the image would still be located at approximately 12.27 cm from the lens, have a height of approximately 0.263 cm, and be real, inverted.

What is the magnitude of the total linear acceleration at t = 0 of a point on the object that is 8.5 cm from the axis?

Answers

The magnitude of the total linear acceleration at t = 0 for a point on the object 8.5 cm from the axis is 11.9 cm/s².

To find the linear acceleration, we first need to determine the angular acceleration (α) and angular velocity (ω) at t = 0.

1. Differentiate θ(t) with respect to time to find the angular velocity: ω(t) = d(θ(t))/dt = βθ0 * \(e^\beta^t\)
2. Differentiate ω(t) to find the angular acceleration: α(t) = d(ω(t))/dt = β²θ₀ * \(e^\beta^t\).
3. Plug in t = 0 into both equations: ω(0) = βθ₀ and α(0) = β²θ₀.
4. Calculate the radial (ar) and tangential (at) linear accelerations: ar = rω² and at = rα.
5. Add ar and at in quadrature to find the total linear acceleration: a_total = √(ar² + at²).

With the given values of β = 2 s⁻¹, θ₀ = 0.7 rad, and r = 8.5 cm, the total linear acceleration is 11.9 cm/s².

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.

The distance from one peak to the next peak is called wavelength. This distance is also equal to the distance from one trough of a wave to another.

Mathematically, wavelength is calculated using this formula;

\( Wavelength = \frac {speed}{frequency} \)

To calculate the magnitude of the electric field of a  particle A moving in a straight line through the magnetic field, we'll use the equation:

E = B * v

where,

E is the magnitude of the electric field.

B is the magnitude of the magnetic field.

v is the velocity of particle A.


The direction of the electric field should be such that the force acting on the particle due to the electric field :

F_ electric = q * E

where,

q is the charge of the particle is equal and opposite to the force acting on the particle due to the magnetic field

F_magnetic = q * v * B * sin(Ф)

where,

Ф is the angle between the velocity and the magnetic field.

In this case, theta is 90 degrees, so sin(Ф) = 1.

To ensure the net force is zero, the electric field lines must be perpendicular to the magnetic field lines and the direction of the particle's velocity.

This way, the forces due to the electric and magnetic fields cancel each other out, keeping the particle moving in a straight line.

a hemisphere of ice with radius r rests so with its flat surface fixed to the ground. a block starts at rest at the top of the hemisphere and is given a nudge so that it slides (without friction) down the slope. how high above the ground will the block be when it looses contact with the ice (hint: what has to be zero when the block loses contact with the ice)?

Answers

The height of the block from ground is  when block loses contact with the ice. This can be solved by using energy conservation and centrifugal force.

Initially the block is placed at a height of r because the height of the hemisphere would be the radius.

So total energy would be = mgr

when it is going to leave the surface, there will be some kinetic and static energy,

so total energy = 1/2 x m x v^2 + m x g x rcosФ

from conservation of energy theorem, we can write

Total energy before = total energy after

mgr = 1/2 x m x v^2 + m x g x rcosФ

2 gr = v^2 + 2 x g x rcosФ

Again, when the object is loosing the contact, that time the centrifugal force will be equal to the vertical force,

(m x v^2)/r = mgcosФ

=> v^2 = grcosФ

putting the values in the above equation

2gr = grcosФ + 2grcosФ

cosФ = 2/3

Also, we can find that when object is losing the contact, the height of the object would be = rcosФ

= r x 2/3

= 2r/3

Hence the height of the object when it is losing the contact is 2r/3.

To prove Newton's second law of motion,

Given Force F = Δp/Δt

What is relation between F = ma and F = Δp/Δt?Newton’s Second Law of Motion is defined as Force is equal to the rate of change of momentum. The second law of Newton can be described as the acceleration of an object which produces a net force is directly proportional to the magnitude of the net force, in the same path i.e., direction as the net force, and inversely proportional to the mass of the object.As the acceleration has its magnitude and direction it is a vector quantity.

Proof for F=ma

     Let us consider an object of mass m, moving along a straight line with an initial velocity u, final velocity v and it has some particular time t and thus Momentum can be related as,

For initial velocity u, p1 = m × u

The final velocity v, p2 = m × v

The change in momentum can be expressed as

p2 – p1 = (m × v) – (m × u)

p2 – p1 = m (v – u)

Here, we know that the rate of change of momentum with respect to time is proportional to the applied force.

The applied force F,

F ∝ [m (v – u)]/t

F ∝ m × a

As acceleration (a) is the rate of change of velocity with respect to time.

F = k × m × a

RMS or root mean square current/voltage of the alternating current/voltage represents the D.C current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2.

A train is moving with the velocity 10 m/s. It attains an acceleration of 4 m/s² after 5 seconds. Find the distance covered by the train in that time. ​

Answers

The train covers a distance of 100 meters in the given time.

To find the distance covered by the train in the given time, we can use the equations of motion.

S = ut + (1/2)at²

The equation S = ut + (1/2)at² is derived from the basic equations of motion. The first term (ut) represents the distance covered in the initial velocity u multiplied by time t. The second term (1/2)at² represents the distance covered due to the acceleration a during time t.

The initial velocity (u) of the train is 10 m/s, and the acceleration (a) is 4 m/s². We are given that this acceleration is attained after 5 seconds, so the time (t) is also 5 seconds. We need to find the distance covered (S).

Substituting the given values:

S = (10 m/s)(5 s) + (1/2)(4 m/s²)(5 s)²

S = 50 m + (1/2)(4 m/s²)(25 s²)

S = 50 m + 50 m

b) The required air feed rate is approximately 65.9 kmol/h. If the combustion were only 65% complete, the required air feed rate would increase to approximately 101.4 kmol/h.

a) To calculate the molar composition on a wet basis, we convert the weight percentages to mole fractions using the molar masses of propane, n-butane, and water. The molar composition is determined by dividing the weight percentage by the respective molar mass and normalizing the values to sum up to 1. The ratio of mol H₂O to mol dry gas is determined by dividing the mol water by the sum of mols of propane and n-butane.

b) To calculate the required air feed rate, we use the stoichiometry of the combustion reaction between butane and air. The balanced equation shows that 1 mol of butane reacts with 13.5 mol of air. Considering the 25% excess air requirement, we multiply the stoichiometric air requirement by 1.25. If the combustion is only 65% complete, the remaining butane requires additional air to achieve complete combustion. Therefore, the required air feed rate increases to account for the unreacted butane.
