a 40cm diameter wheel accelerates uniformly from 240 rpm to 360 rpm in 6.5 seconds. how far will a point on the edge of the wheel have traveled in this time

Answers

Answer 1

Answer:

S = V1 t + 1/2 a t^2        distance traveled for linear acceleration

θ = ω1 t + 1/2 α t^2       equivalent angle for rotational acceleration

ω1 = 240 / min * 2 π * 240 / (60 s/min) = 8 π / s

ω2 = 360 rpm = 12 π / s

α = 4 π/ 6.5 s^2  = .62 π / s^2    angular acceleration

θ = 8 π / s  6.5 s + .62 π / 2 * 6.5^2

θ = 52 π + 13 π = 65 π = 65 * π / (2 π / rev) = 32.5 rev

1 rev = 2 * π * R = 2 * π * .4 m = 2.51 m / rev

S = 32.5 rev * 2.5 m/rev =  81 m

A ball that rolls on the ground is initially propelled with a speed of 45 km / h and after 10 seconds it stops. Assuming you lost speed constantly, then: a) Calculate the acceleration b) Calculate the distance traveled.

Answers

Answer:

a) -1.25 m/s²

b) 62.5 m

Explanation:

Convert km/h to m/s:

45 km/h × (1000 m/km) × (1 h / 3600 s) = 12.5 m/s

a = Δv / Δt

a = (0 m/s − 12.5 m/s) / 10 s

a = -1.25 m/s²

Δx = ½ (v + v₀) t

Δx = ½ (0 m/s + 12.5 m/s) (10 s)

Δx = 62.5 m

Answers

The frictional force exerted by the road on the car is 3000N

Given the mass of the car is 1000 kg , the velocity of the car is 20m/s

and the time is 6.6s

We need to find the frictional force exerted by the road on the car

We know that Force = mass * acceleration

Now here Mass is given but acceleration is not given

So, we will find acceleration by using the formula v = u+at

Where u = 0

v = 20m/s

a = ?

t = 6.6

Substitute the values in the formula We get

v = u+at

20 = 0+(a)(6.6)

20/6.6 = a

∴ a = 3.03 m/s^2

Rounding to nearest tenth is 3m/s^2

Hence the acceleration is 3m/s^2

Now substituting the value of acceleration in F = ma

Where m = mass

a = acceleration

F = 1000*3

∴ F = 3000N

Hence the frictional force exerted by the road on the car is 3000 N

Answers

The frequency of oscillation for the spring system of part i is 0.719 Hz.

Explanation: The frequency of a system is a measure of the number of cycles it completes per second, which is proportional to the square root of the ratio of the spring constant to the mass of the system.

In this case, the spring constant is given as k=2.5 N/m and the mass of the system is given as m=0.35 kg. Plugging these values into the equation for frequency, we get frequency (f) = 1/2π * sqrt(k/m) = 1/2π * sqrt(2.5/0.35) = 0.719 Hz.

Why are relativistic calculations particularly important for electrons​

Answers

Relativistic calculations are particularly important for electrons because they move at very high speeds, which means they have a significant fraction of the speed of light.

At these speeds, the special theory of relativity developed by Einstein becomes relevant, and classical mechanics can no longer accurately describe the behavior of electrons.

Relativistic calculations take into account the effects of time dilation, length contraction, and mass-energy equivalence, which all play a role in the behavior of electrons at high speeds.

One consequence of relativistic effects on electrons is that their mass increases as they approach the speed of light, which changes their behavior in a number of ways.

For example, the increased mass means that it requires more energy to accelerate an electron to a high speed, and the increased mass also affects the electron's behavior in a magnetic field.

Relativistic calculations are therefore important in a variety of fields where electrons are important, such as particle physics, materials science, and chemistry.

According to eq. 6. 134, the x-velocity in fully developed laminar flow between parallel plates is given by u = 1 2μ ( ∂p ∂x) (y2 − h2) the y-velocity is υ = 0. Determine the volumetric strain rate, the vorticity, and the rate of angular deformation. What is the shear stress at the plate surface?

Answers

The volumetric strain rate is zero, the vorticity is -1/2μ (∂p/∂x) y, the rate of angular deformation is 1/2μ (∂p/∂x) y, and the shear stress at the plate surface is -1/2 (∂p/∂x) \(h^2\).

Given:

x-velocity: u = 1/2μ (∂p/∂x) (\(y^2 - h^2\))

y-velocity: υ = 0 (no variation in y-direction)

where,

μ = dynamic viscosity

p = pressure

x, y = coordinates

h = distance between the plates

To determine the volumetric strain rate, we can start by considering the continuity equation for incompressible flow, which states that the product of velocity and cross-sectional area is constant:

u × (h-y) = Q/A

where A is the cross-sectional area and Q is the volumetric flow rate.

Taking the derivative of both sides with respect to time and simplifying, we get:

dQ/dt = -u × dA/dy

Since the y-velocity is zero, we have dA/dy = 0, so:

dQ/dt = 0

This means that the volumetric flow rate is constant and there is no change in volume with time. Therefore, the volumetric strain rate is zero.

The velocity vector's curl is used to define the vorticity.

ω = ∇ x v

where ∇ is the del operator. For two-dimensional flow, the vorticity is a scalar and can be expressed as:

ω = (∂υ/∂x) - (∂u/∂y)

Substituting the given values for u and υ, we get

ω = 0 - (∂/∂y)[1/2μ (∂p/∂x) (\(y^2 - h^2\))]

Simplifying and integrating with respect to y, we get:

ω = -1/2μ (∂p/∂x) y

The formula for angular deformation rate is:

D = (∂u/∂y + ∂υ/∂x) = ∂u/∂y

Substituting the given value for u, we get:

D = (∂/∂y)[1/2μ (∂p/∂x) \((y^2 - h^2)\)]

Simplifying and integrating with respect to y, we get:

D = 1/2μ (∂p/∂x) y

To find the shear stress at the plate surface, we can use the following relation:

τ = μ (∂u/∂y)|y=h

Substituting the given value for u, we get:

τ = μ (∂/∂y)[1/2μ (∂p/∂x) (\(y^2 - h^2\))]|y=h

Simplifying, we get:

τ = -1/2 (∂p/∂x) \(h^2\)

Therefore, the volumetric strain rate is zero, the vorticity is -1/2μ (∂p/∂x) y, the rate of angular deformation is 1/2μ (∂p/∂x) y, and the shear stress at the plate surface is -1/2 (∂p/∂x) \(h^2\).

The difference between periodic motion and oscillatory motion is that "​all oscillatory motion is periodic, but not all periodic motion is oscillatory."

What is periodic and oscillatory motion?

Periodic motion and oscillatory motion are both types of repetitive motion, but there are subtle differences between the two.

The periodic motion refers to any motion that repeats itself after a fixed interval of time, called the period. The motion may not necessarily be back and forth or side to side; it can be any type of repetitive motion.

For example, a planet orbiting the sun exhibits periodic motion because it repeats its path around the sun after a fixed period of time.

Oscillatory motion, on the other hand, specifically refers to repetitive back-and-forth or to-and-fro motion around a fixed point or equilibrium position. This means that the motion has an amplitude (the maximum displacement from the equilibrium position) and a frequency (the number of oscillations per unit of time).

Examples of oscillatory motion include a pendulum swinging back and forth, a spring bouncing up and down, or a wave moving up and down in the water.

Therefore, all oscillatory motion is periodic, but not all periodic motion is oscillatory.

A 10-kg box initially moving at 5. 31 m/s slides 4. 87 m across the floor before coming to rest. Use the Work-Kinetic energy theorem to find the coefficient of kinetic friction between the floor and the box

Answers

The coefficient of kinetic friction between a 10-kg box initially moving at 5. 31 m/s slides 4. 87 m across the floor before coming to rest is 0.418.

The Work-Kinetic energy theorem states that the work done on an object is equal to the change in its kinetic energy. In this case, the work done on the box is due to the friction between the box and the floor. The kinetic energy of the box initially is given by

KE₁ = (1/2)mv²

where m is the mass of the box and v is its velocity. The kinetic energy of the box at rest is zero, so the change in kinetic energy is -KE₁.

The work done on the box by friction is given by W = Fd, where F is the force of friction and d is the distance the box slides. Since the box comes to rest, the force of friction is equal in magnitude to the force pushing the box, which is given by F = ma, where a is the acceleration of the box and is equal to -v₂/(2d).

Therefore,

F = -ma

= -(m/2d)v₂

Substituting this expression for F into the equation for work, we get

W = -(m/2d)v²

d = -(1/2)mv²

Equating this to the change in kinetic energy, we get:

-(1/2)mv² = -(1/2)mv₂ × mu

where mu is the coefficient of kinetic friction.

Solving for mu, we get:

mu = (d/v)²

= (4.87/5.31)²

= 0.418.

Therefore, the coefficient of kinetic friction between the floor and the box is 0.418.

The frequency of electromagnetic radiation having a wavelength of 577.0 nm is 5.20 x 10¹⁴ Hz.

The frequency (f) of electromagnetic radiation can be calculated using the formula: f = c/λ, where c is the speed of light and λ is the wavelength of the radiation.

Given the wavelength of the electromagnetic radiation as 577.0 nm and the speed of light as c = 3.00 x 10⁸ m/s, we need to convert the wavelength from nanometers (nm) to meters (m) before we can calculate the frequency.

So, 577.0 nm = 577.0 x 10⁻⁹ m

Now we can use the formula to find the frequency:

f = c/λ = (3.00 x 10⁸ m/s)/(577.0 x 10⁻⁹ m)

f = 5.20 x 10¹⁴ Hz

Answers

Satellite B orbits exoplanet A in a circular motion with a constant speed, completing one orbit every 7.14 days.

The period of satellite B's orbit around exoplanet A is 7.14 days. This means that it takes 7.14 days for the satellite to complete one full revolution around the planet. The fact that the orbit is described as "constant-speed circular motion" indicates that the satellite moves in a circular path around the planet with a consistent speed. In a circular orbit, the satellite maintains a fixed distance from the planet throughout its journey. The orbital speed of the satellite remains constant, meaning that it covers equal distances in equal intervals of time. This behavior is consistent with the laws of planetary motion, particularly Kepler's laws, which govern the motion of objects in space. Therefore, based on the given information, we can conclude that satellite B consistently completes one orbit around exoplanet A every 7.14 days in a circular path with a constant speed.

What is the direction of a descending pass for an amateur satellite? / A. From north to south / B. From west to east / C. From east to west / D. From south to north

Answers

A. From north to south. Amateur satellites in polar orbits typically have descending passes from north to south.

Amateur satellites, like many other satellites, often follow polar orbits, circling the Earth from the North Pole to the South Pole and vice versa. As they traverse this orbit, the descending pass refers to the portion of the satellite's orbit when it moves from the northern latitudes towards the southern latitudes.

This means that during a descending pass, an amateur satellite will appear to move from north to south across the sky. This direction allows for coverage of different regions of the Earth during each orbit, as the satellite crosses various latitudes from higher to lower as it descends.

according to stefan's law (see section 3.4 in the textbook), how much more radiation - per square meter, say - is emitted by venus's surface at 730 k than is emitted by earth's surface at 300 k ? express your answer using two significant figures.

Answers

The surface of Venus emits about 58.2 times more radiation per square meter than the surface of Earth, assuming they both behave as black bodies.

Stefan's law states that the energy radiated per unit area per unit time, or the radiant emittance, of a black body is proportional to the fourth power of its absolute temperature. Mathematically, this can be written as:

E = \(σT^4\)

where E is the radiant emittance, σ is the Stefan-Boltzmann constant (\(5.67 x 10^-8 W/m^2K^4\)), and T is the absolute temperature.

Using this formula, we can calculate the ratio of the radiant emittance of Venus's surface at 730 K to that of Earth's surface at 300 K:

(\(E_venus / E_earth) = (σT_venus^4 / σT_earth^4\))

(\(E_venus / E_earth) = (T_venus / T_earth\))\(^4\)

(\(E_venus / E_earth) = (730 / 300)^4\)

(\(E_venus / E_earth) ≈ 58.2\)

Therefore, the surface of Venus emits about 58.2 times more radiation per square meter than the surface of Earth, assuming they both behave as black bodies.

Actually Welcome to the Concept of the Potential Energy.

Here lets calculate it one by one ;-

1.) P = mgh ==> 100*9.81*202===> 198162 Joules

2.) P = mgh ==> 90*9.81*202 ==> 178345.8 Joules

3.) P = mgh ===> 45*9.81*202 ===> 89172.9 Joules

4.) P = mgh ===> 58*9.81*202 ===> 114933.96 Joules

5.) P = mgh ===> 0.001*9.81*202 ===> 1.981 Joules

6.) P = mgh ===> 1.00*9.81*202 ===> 1981.62 Joules

7.) P = mgh ===> 1.998*9.81*202 ==> 3959.27 Joules

8.) P = mgh ===> 1.5*9.81*202 ===> 2971.43 Joules

9.) P = mgh ===> 0.1*9.81*202 ===> 198.162 Joules.

Answers

1.8 x 10-3 N to the left is the strength and guidance of the net electrostatic force on q1.

Where may one find electrostatic force?

The size of each charge & the separation between them determine how much electrostatic force there will be. When two charges of the same type are brought together, whether positive or Two charges positioned apart are subject to the electrostatic force., they repel one another.

What is electrostatic force, and what does it look like?

The mathematical formula for the electrostatic attraction between two objects was initially published by a Frenchman named Charles Coulomb. The force between the charged points can be calculated using Coulomb's law. Its formula is F=k|q1q2|r2, where q1 as well as q2 correspond to two point charges that are separated from one another by r, and where k=8.99109Nm2/C2.
