The final image is formed by two converging lenses at 15.3 cm in front of the second lens and the magnification of the system is -0.99.

To find the location of the final image, we can use the lens formula:

1/f = 1/do + 1/di

where f is the focal length of the lens, do is the object distance, and di are the image distance.

For the first lens, f = 14.8 cm and do = 30.0 cm. Plugging these values into the lens formula gives:

1/14.8 = 1/30 + 1/di

Solving for di, we get:

di = 20.1 cm

This means that the first lens forms an image 20.1 cm behind it, which serves as the object for the second lens.

Using the lens formula again for the second lens, f = 14.8 cm and do = 39.7 - 20.1 = 19.6 cm. Plugging these values into the lens formula gives:

1/14.8 = 1/19.6 + 1/di

Solving for di, we get:

di = 9.1 cm

Therefore, the final image is formed 9.1 cm behind the second lens.

To find the magnification of the system, we can use the formula:

m = - di/do

where m is the magnification, di is the image distance, and do is the object distance.

Plugging in the values we found, we get:

m = -9.1/30.0 = -0.303

Therefore, the magnification of the system is -0.303, which indicates that the image is inverted and smaller than the object.

Answer:

a. 86.80 m

b. i. The mass of the bob

ii. The length of the pendulum

Explanation:

a. Determine the height of the smokestack.

Using T = 2π√(L/g) where T = period of pendulum = 18.7 s, L = length of pendulum = height of smokestack and g = acceleration due to gravity = 9.8 m/s².

So, making L subject of the formula, we have

T = 2π√(L/g)

T/2π = √(L/g)

squaring both sides, we have

(T/2π)² = L/g

L = (T/2π)²g

Substituting the values of the variables into the equation, we have

L = (T/2π)²g

L = (18.7 s/2π)²(9.8 m/s²)

L = (2.976 s)²(9.8 m/s²)

L = 8.857 s² × 9.8 m/s²

L = 86.796 m

The magnitude of the change in potential energy experienced by the electron is a. 1500 eV.

Potential difference = 1500V

Charge of an electron = -1.6 x 10^-19

The energy that is capable of changing into another form of energy is called potential energy. The potential energy of an object is influenced by its physical characteristics and location within a system. Potential energy can take on various shapes. For example: due to an object's mass and location within a gravitational field, it has the potential energy of gravity.

Calculating the magnitude of the change in potential energy -

ΔPE = qΔV

Substituting the values -

\(PE = (-1.6 x 10^-19 C) x (1500 V)\)

\(PE = -2.4 x 10^-16 J\)

Converting to electron volts (eV) -

To find the angle at which the ball enters the basket, we need to use the equations of motion for projectile motion. The equations are:
y = y0 + v0y*t - (1/2)*g*t^2
x = x0 + v0x*t
where y is the vertical position, y0 is the initial vertical position, v0y is the initial vertical velocity, g is the acceleration due to gravity, t is the time, x is the horizontal position, x0 is the initial horizontal position, and v0x is the initial horizontal velocity.

The ball enters the basket at an angle of 0° to the horizontal.

We know that
y0 = 2.4 m, v0 = 12 m/s, θ0 = 35°, and g = 9.8 m/s^2. We can find v0x and v0y using the angle:
v0x = v0*cos(θ0) = 12 m/s*cos(35°) = 9.82 m/s
v0y = v0*sin(θ0) = 12 m/s*sin(35°) = 6.92 m/s
The ball enters the basket when y = 0, so we can set the equation for y equal to 0 and solve for t:
0 = 2.4 m + 6.92 m/s*t - (1/2)*9.8 m/s^2*t^2
Using the quadratic formula, we find that t = 0.74 s or t = -0.63 s. We discard the negative value, so t = 0.74 s.
Now we can use the equation for x to find the horizontal position of the basket:
x = x0 + v0x*t = 0 + 9.82 m/s*0.74 s = 7.27 m
Finally, we can use the equation for the tangent of the angle to find the angle at which the ball enters the basket:
tan(θ) = y/x = 0/7.27 m = 0
θ = tan^-1(0) = 0°

The light travels through water and gets reflected off on the glass surface into the water. There had been a 180° phase change between the incident and the reflected wave. This is called Total internal reflection (TIR).

In total internal reflection, in physics, a ray of light in a medium such as water or glass is completely reflected back into the medium from the surrounding surfaces. This phenomenon occurs when the angle of incidence is greater than a certain critical angle called the critical angle.

TIR only occurs when both of the following two conditions are met

Thus, the phases which include the TIR are the incident and the reflected phase and the incident light hits the surface while the reflected light reflects back.

Anaphase

Explanation:

This is because the spindle fibres have shortened and is pulling the chromatids towards the poles of the cell. The chromatids have also separated.

The cell division which is shown in the picture is anaphase. The correct option is C.

Meiosis is divided into two main phases, each with its own set of subphases:

1 Meiosis I:

a. Prophase I: This is the longest and most complex phase of meiosis. During this phase, homologous chromosomes pair up and form bivalents, and crossing over occurs between the homologous chromosomes. The nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase I: During this phase, the homologous chromosomes line up along the metaphase plate, with one chromosome from each homologous pair facing each pole of the cell.

c. Anaphase I: During this phase, the spindle fibers contract and pull the homologous chromosomes towards opposite poles of the cell.

d. Telophase I: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in two daughter cells.

2. Meiosis II:

a. Prophase II: During this phase, the nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase II: During this phase, the chromosomes line up along the metaphase plate, with sister chromatids facing opposite poles of the cell.

c. Anaphase II: During this phase, the spindle fibers contract and pull the sister chromatids towards opposite poles of the cell.

d. Telophase II: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in four haploid daughter cells.

Meiosis involves two rounds of chromosome segregation, resulting in four haploid daughter cells that are genetically distinct from the parent cell.

The correct option would be option B. 8.20 seconds. The motion of the golf ball can be divided into two phases. They are; The time for the golf ball to reach the maximum height and the time for the golf ball to return to the ground. The time for the golf ball to reach the maximum height is half of the total hang time.

The given figure is shown below:

Given,

Initial velocity, u = 15 m/s (upward direction)

Final velocity, v = 0 m/s (at the maximum height)

Acceleration, a = g = 9.8 m/s² (downward direction)

Time taken to reach the maximum height, t = 3 seconds

The formula to find the height of the golf ball is given by;

h = ut + 1/2at²h = 15 x 3 + 1/2 x 9.8 x 3²h = 67.05 m

Answer:

67%

Explanation:

In the absence of external forces, the total momentum of the system before the collision is equal to the total momentum after the collision. Since the second ball is initially at rest, the total momentum before the collision is simply m*v.

After the collision, the two balls stick together and move with a common velocity, which can be calculated using conservation of momentum:

m*v + 0 = (m+2m) * v_final

Solving for v_final, we get:

v_final = v/3

The initial kinetic energy of the system is:

K_i = 0.5mv^2

The final kinetic energy of the system is:

K_f = 0.5*(3m)v_final^2 = 0.5(3m)(v^2/9) = 0.5m*v^2/3

The fraction of the initial kinetic energy lost on impact is:

( K_i - K_f ) / K_i = ( 1 - 1/3 ) = 2/3 = 0.67

Therefore, 67% of the initial kinetic energy is lost on impact.

A mirror reverses left and right but not up and down because it reflects light rays without changing the orientation of objects in relation to gravity, while our perception of left and right is influenced by our own point of view.

The phenomenon of a mirror reversing left and right but not up and down is a result of the way reflections occur.

When we look at an object in a mirror, the mirror reflects the light rays that enter our eyes. The mirror doesn't actually change the orientation of the object itself. However, our perception of the reflected image is influenced by how we interpret the direction of the reflection.

Left and right are relative orientations based on our own point of view. When we face a mirror, our left side appears on the mirror's right side, and our right side appears on the mirror's left side. This reversal occurs because the mirror reflects light rays in a way that preserves the angles at which they strike the mirror's surface.

On the other hand, up and down are absolute orientations in relation to gravity. Gravity pulls objects in a consistent downward direction, and the mirror does not alter the orientation of objects with respect to gravity. Therefore, the reflection in the mirror appears to maintain the same up-down orientation.

If the voltmeter holds steady at 45 V and the ammeter reading holds steady at 5.0 A. It would take approximately 12133.3 seconds, or about 3.37 hours, time to completely vaporize the water in the beaker.

Since the voltmeter reading and ammeter reading hold steady, the power input to the water is constant. The power input is given by the product of the voltage and current

P = VI = (45 V)(5.0 A) = 225 W

The energy required to vaporize the water can be found using the heat of vaporization of water

Q = mL = (1 kg)(2.3 x \(10^{6}\) J/kg) = 2.3 x \(10^{6}\)  J

The energy required to raise the temperature of the water from room temperature to boiling can be found using the specific heat of water

Q = mcΔT = (1 kg)(4.2 kJ/kg. C)(100 C) = 420 kJ = 420,000 J

The total energy required to completely vaporize the water is the sum of the energy required to raise the temperature and the energy required to vaporize

Qtotal = Q + 420,000 J = 2.3 x \(10^{6}\)  J + 420,000 J = 2.72 x \(10^{6}\)  J

The time required to deliver this amount of energy at a constant power of 225 W is

t = Qtotal / P = (2.72 x \(10^{6}\) J) / (225 W) = 12133.3 s

If the time period of the pendulum in earth is 1 seconds, then the length  L is 0.24 m. If length in mars is L/2 and acceleration due to gravity is 1/3rd of that of earth, the time period of the pendulum on mars is 1.216 seconds.

The time period of oscillation of a pendulum is the time taken to complete oscillation. It is related to the length l, and acceleration due to gravity g as:

T = 2π √l/g

T for earth = 1 s

g for earth = 9.8 m/s²

then l = T/4π² × g

l = 1/4π²× 9.8 m/s²

If in mars L = L/2 = 0.24 /2 = 0.12 m

g = 9.8 m/s²/3 = 3.22m/s²

Then time period T = 2π × √0.12 m/3.22m/s²
