Centripetal acceleration is = 10π^2    cm/s.

Centripetal acceleration is = r×(W)^2.

The radius of the circular path is 0.1 m or 10 cm.

Centripetal acceleration is = r×(W)square.

Area=0.1×(π)square                 cm/s square.

Area=10π^2                              cm/s square.

Acceleration of an object in a circular orbit. Since velocity is a vector quantity that is it has both magnitudes velocity and direction as an object moves along a circular path, its direction and velocity constantly change, resulting in acceleration. The centripetal force causes centripetal acceleration.

In the special case of the earth orbiting the sun or satellites orbiting celestial bodies the centripetal force causing motion is the result of the gravitational pull between them. Centripetal acceleration is defined as the property of motion of a body through a circular orbit. An object that moves in a circle and has an acceleration vector pointing to the center of the circle is called centripetal acceleration.

The planes are 246.06 miles apart after 2 hours.

According to the question, Two planes take off at the same time from an airport. The first plane is flying at 272 miles per hour on a course of 155.0° and the second plane is flying at 336 miles per hour on a course of 175.0°.

                                          a = 544 miles

                                           b = 672 miles

                                           x = 25°

                                            y = 5°

                                            C = 20°

Using the law of cosines, we can calculate the distance between the two planes.

               Law of cosines ⇒  \(c^{2} = a^{2} + b^{2} - 2ab.cosC\)    → 1

Substitute a = 544, b = 672 and C = 20° in 1, then we get

                           \(c^{2} = 544^{2} + 672^{2} - 2(544)(672).cos(20)\)

                               =  295936 + 451584 - 2(365568).(0.9396)

                               =  747520 - (731136).(0.9396)

                               =  747520 - 686975.3856

                           \(c^{2}\)  =  60544.6144

                           c = \(\sqrt{60544.6144}\)

                           c = 246.058 ≅ 246.06

Therefore, the distance between the two planes after two hours is 246.06 miles.

The factors that can change the pattern observed on a screen during Young's double-slit experiment are given below:1. Width of the slit. 2. Distance between slits. 3. Distance between slits and screen. 4. Wavelength of the incident light. 5. Refractive index of the medium.

The factors that can change the pattern observed on a screen during Young's double-slit experiment are given below:

1. Width of the slit. The width of the slit can influence the diffraction pattern that is observed on a screen. When the width of the slit decreases, the central maximum of the diffraction pattern becomes broader, and the intensity of the secondary maxima reduces.

2. Distance between slits. The distance between the slits in the double-slit experiment also affects the pattern on the screen. The distance between the slits is equal to the spacing between the maxima. If the spacing between the slits decreases, the distance between the maxima decreases, and vice versa.

3. Distance between slits and screen. The distance between the slits and the screen is also a factor that can affect the diffraction pattern. When the distance increases, the spacing between the maxima becomes wider, and the intensity of the maxima decreases.

4. Wavelength of the incident light. The wavelength of the incident light is another factor that affects the diffraction pattern on the screen. When the wavelength increases, the spacing between the maxima increases, and vice versa.

5. Refractive index of the medium. The refractive index of the medium in which the light travels can also influence the diffraction pattern observed on a screen.

When the refractive index of the medium changes, the position of the maxima changes as well. These are the factors that can change the pattern observed on a screen during Young's double-slit experiment.

(a) The force between the two spheres can be calculated using Coulomb's Law:

F = k * Q^2 / R^2

where k is Coulomb's constant, Q is the charge on each sphere, and R is the distance between the centers of the spheres.

The force on sphere A due to sphere B is the same as the force on sphere B due to sphere A, and it is given by:

F_AB = F_BA = k * Q^2 / R^2

(b) When sphere C is brought into contact with sphere B, the charge on sphere B will distribute evenly between sphere B and C, since they are in contact. The total charge on sphere B plus C remains equal to Q, since sphere C started with zero charge.

When sphere C is moved far away, the net force on sphere A due to sphere B and C will be the same as the force due to sphere B alone, since the charge on sphere C has been moved far away and has no effect on the force between the spheres. So the net force on sphere A is:

F_AB = F_BA = k * Q^2 / R^2

(c) When sphere C is brought into contact with sphere A, the charge on sphere A will distribute evenly between sphere A and C, since they are in contact. The total charge on sphere A plus C remains equal to Q, since sphere C started with zero charge.

When sphere C is moved far away, the net force on sphere A due to sphere A and C will be zero, since they now have equal and opposite charges and are separated by a large distance. Therefore, the net force on sphere A is the force due to sphere B alone:

F_AB = F_BA = k * Q^2 / R^2

Part A: If the separation of the slits in a two-slit experiment is decreased, the spacing between the fringes will increase.

Part B: If the two-slit experiment is immersed in water, the spacing between the fringes will decrease.

Part A: If the separation of the slits in a two-slit experiment is decreased, the spacing between the fringes will increase.

The spacing between the fringes in a two-slit experiment is determined by the wavelength of the light used and the separation of the slits. According to the formula for fringe spacing, given by

dλ = mλ / D

Where d is the fringe spacing, λ is the wavelength of light, m is the order of the fringe, and D is the distance from the slits to the screen.

If the separation of the slits is decreased, the value of d in the equation increases. Since the wavelength of light remains constant, an increase in d leads to an increase in the spacing between the fringes.

Therefore, the spacing between the fringes will increase if the separation of the slits is decreased.

Part B: If the two-slit experiment is immersed in water, the spacing between the fringes will decrease.

The refractive index of water is greater than that of air. When light passes from air to water, its speed decreases. Since the speed of light in a medium affects the wavelength, the wavelength of light in water is shorter compared to its wavelength in air.

In the formula for fringe spacing mentioned earlier, the wavelength of light is involved. If the wavelength decreases due to the change in medium (from air to water), the spacing between the fringes will also decrease.

Therefore, the spacing between the fringes will decrease if the two-slit experiment is immersed in water.

The ball's centripetal acceleration is 119.2 m/s^2.

The centripetal acceleration (a) of an object moving in a circle can be calculated using the formula:

a = (v²) / r

where v is the velocity of the object and r is the radius of the circle.

In this problem, we are given the frequency (f) of the ball's motion, which is related to its velocity (v) and the radius (r) of the circle by the equation:

v = 2πrf

We are also given the length (L) of the string, which is equal to the radius (r) of the circle.

Substituting the given values into the equations, we get:

r = L = 48 cm = 0.48 m

f = 2.5 Hz

v = 2πrf = 2π(0.48 m)(2.5 Hz) = 7.54 m/s

Using the formula for centripetal acceleration, we get:

a = (v²) / r = (7.54 m/s)² / 0.48 m = 119.2 m/s²

Therefore, the ball's centripetal acceleration is 119.2 m/s².

Answer:

Time, t = 10 seconds

Explanation:

Given the following data;

Mass = 10kg

Force = 10N

Final velocity = 10m/s

Initial velocity = 0m/s

To find the time;

First of all, we would find the acceleration of the box.

Force = mass * acceleration

10 = 10 * acceleration

Acceleration = 10/10 = 1m/s²

Now, we can find the time by using the first equation of motion;

V = U + at

10 = 0 + 1t

10 = t

Time, t = 10 seconds

Therefore, it will take 10 seconds for the box to come to a complete stop.

Hi there!

We can use the work-energy theorem to solve.

Recall that:
\(E_i = E_f\)

The initial energy equals the final energy (Conservation of Energy). However, we must take into account energy dissipated due to friction in this instance.

The energy lost due to friction is equivalent to the work done by friction. Recall the following:

The work due to a force is:
\(W = F \cdot d \\\)

Since the displacement is in the same direction as the force, the dot-product becomes Fd.

The work due to friction then becomes:

\(W_f = \mu mgdcos\theta\)
The work due to friction is SUBTRACTED from the initial potential energy.

Initial energy = GPE = mgh

Final energy = KE

Therefore:

\(\boxed{mgh - \mu mgdcos\theta = KE}\)

At the time of the summer solstice, the noontime altitude of the sun is at its highest point, around 90°.

Altitude is the height above sea level. It is typically measured in either metres or feet. In aviation, altitude can also refer to the vertical distance between an aircraft and a certain reference point on the ground. Altitude can be used to determine the air pressure, temperature, and density of the air. Altitude can also be used to calculate the distance a plane can travel without refueling. Altitude can play an important role in the weather of an area, as air pressure and temperature tend to decrease with altitude. Altitude can also affect the type of vegetation found in an area. In mountain regions, the altitude can have a dramatic effect on the climate, creating distinct areas of vegetation and wildlife. Altitude can also affect the types of crops that can be grown in an area, depending on the air pressure, temperature, and precipitation.

a) Sketch the plate shape: we get a shape that resembles a trapezoid.

The plate shape is determined by the lines y = 2 - x² and y = 2x - 1. To sketch the plate shape, we can plot these two lines and shade the region in between them. The intersection points of the lines are found by solving the equations simultaneously:

2 - x² = 2x - 1

Simplifying, we get:

x² + 2x - 3 = 0

Factoring, we have:

(x - 1)(x + 3) = 0

So, x = 1 and x = -3. Plugging these values into the equations of the lines, we find the corresponding y-values:

For x = 1:

y = 2 - (1)² = 1

For x = -3:

y = 2(-3) - 1 = -7

Plotting these points and connecting them with the lines, we get a shape that resembles a trapezoid.

b) Total charge through the double integral:

To find the total charge Q, we need to integrate the charge density p(x, y) over the entire plate. We can express this as a double integral:

Q = ∬ p(x, y) dA

c) Reducing the double integral to repeated integrals: The limits of integration for x are the values of x that define the boundaries of the plate shape, which are -3 to 1.

Since the plate shape is described by the lines y = 2 - x² and y = 2x - 1, we can rewrite the double integral as a repeated integral by integrating with respect to x and y separately:

Q = ∫∫ p(x, y) dy dx

The limits of integration for y are from the lower curve y = 2 - x² to the upper curve y = 2x - 1. The limits of integration for x are the values of x that define the boundaries of the plate shape, which are -3 to 1.

d) Calculating the integral: The total charge Q of the thin plate is approximately 12.4 mC.

Now, we can evaluate the double integral to find the total charge Q:

Q = ∫(-3 to 1) ∫(2 - x² to 2x - 1) x²y dy dx

Performing the inner integral with respect to y first, we get:

Q = ∫(-3 to 1) [x²(y²/2 - y)] from 2 - x² to 2x - 1 dx

Simplifying the inner integral, we have:

Q = ∫(-3 to 1) [(x²/2)(2 - x²) - x²(2x - 1)] dx

Expanding and simplifying further, we get:

Q = ∫(-3 to 1) (x² - x⁴/2 - 4x³ + 2x²) dx

Integrating term by term, we have:

Q = [x³/3 - x⁵/10 - x⁴ + 2x³/3] from -3 to 1

Evaluating the integral at the limits, we get:

Q ≈ 12.4 mC (rounded to five significant figures)

Therefore, the total charge Q of the thin plate is approximately 12.4 mC.
