Answer:

Fc= 47.363 N

Explanation:

First, you need tangential velocity because they don't give that to you in the problem.

So, the formula for tangential velocity is υ=2πr/t.

For this problem its v=2π4/10= 2.513 m/s

Then we plug this into our equation for centripetal force

Fc= 30*(2.513)^2/4=47.363 N

Fc=47.363 N

The centripetal force acting on Tommy is 47.36 N if Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.

A tangible body's mass is the amount of matter it possesses. It's also a metric of inertia or the resistance to velocity when a net force is exerted.

It is given that:

Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.

As we know the formula for the centripetal force:

Fc = mv²/r

m = 30 kg

r = 4 meters

First, find the tangential velocity:

The formula for tangential velocity is:

v = 2πr/t

v = 2π4/10

v = 2.513 m/s

Plug the values in the formula:

Fc= 30(2.513)²/4

Fc = 47.36 N

Thus, the centripetal force acting on Tommy is 47.36 N if Tommy, who has a mass of 30 kg, sits 4.0 meters from the center of a merry-go-round that is rotating for a period of 10 seconds.

The Index of Refraction of the champagne is approximately 1.00033.

To find the Index of Refraction of the champagne, we need to use the formula:
Index of Refraction = (sin i) / (sin r)
Where i is the angle of incidence (in this case, 30 degrees) and r is the angle of refraction (in this case, 18 degrees).
Plugging in these values, we get:
Index of Refraction = (sin 30) / (sin 18)
Index of Refraction = 1.00033
This means that the speed of light in champagne is about 1.00033 times slower than the speed of light in a vacuum.
Knowing the Index of Refraction is important in understanding how light behaves when it passes through different materials. The amount of refraction that occurs depends on the Index of Refraction of the material, as well as the angle of incidence.

Approximately 2.52 x 10¹⁰ years have elapsed between the two measurements.

The decay constant of uranium-238 is 1.55 x 10⁻¹⁰ per year.

The decay constant can be calculated by using the following formula: λ = ln(2) / T1/2where T1/2 is the half-life of the isotope. By plugging in the values for T1/2 in the formula, we can determine the decay constant of uranium-238.λ = ln(2) / T1/2λ = ln(2) / (4.47 x 10)λ = 1.55 x 10⁻¹⁰.

The decay constant of uranium-238 is 1.55 x 10⁻¹⁰ per year. To determine the amount of time that has elapsed between two measurements, we can use the following formula:N = N₀e^(-λt)where N₀ is the initial amount of the isotope, N is the final amount of the isotope, t is the time that has elapsed, and e is the mathematical constant approximately equal to 2.718.

By rearranging the formula, we can solve for t.t = (ln(N₀) - ln(N)) / λWe can use this formula to calculate the time elapsed between two measurements of uranium-238.

Let's assume that the initial amount of uranium-238 is 100 grams and the final amount is 25 grams. We can plug these values into the formula along with the decay constant we found earlier:t = (ln(100) - ln(25)) / (1.55 x 10⁻¹⁰)t ≈ 2.52 x 10¹⁰ years.

The period of the given object moving with simple harmonic motion is 2.8 seconds.

The period of an object moving with simple harmonic motion(SHM) is related to its acceleration and the force constant, k, which is proportional to the restoring force.

The relationship between acceleration, displacement, and force constant for an object in simple harmonic motion is given by:

a = -(k/m) x

Where a is the acceleration, x is the displacement from the equilibrium point, m is the mass of the object, and k is the force constant.

In this case, the displacement is 4 cm, the acceleration is 20 cm/s², and we can solve for the force constant k:

k/m = a / x = 20 cm/s² / 4 cm = 5 cm/s²

The period T of an object in simple harmonic motion is given by:

T = 2π √(m/k)

We can plug in the value of k and m (which we will assume to be 1 kg for simplicity) to find the period:

T = 2π √(1 kg / (5 cm/s²)) = 2.8 s

The period T is the time it takes for one complete cycle of motion, so it has units of time.

The fish appears to be located 37.6 cm below the surface of the pond when viewed from directly above.The correct answer is: O 37.6 cm below the surface of the pond.

This is because when light travels from water (with an index of refraction of 1.33) to air (with an index of refraction of 1.00), it undergoes refraction. This means that the light bends as it passes through the surface, which causes objects to appear shifted from their actual position.

In this case, the fish is actually located 50.0 cm below the surface of the pond. However, when the light from the fish enters the air above the pond, it bends away from the normal (a line perpendicular to the surface of the water), causing the fish to appear higher up than it actually is. Using the formula for calculating the apparent depth of an object underwater:

apparent depth = real depth / index of refraction

We can calculate the apparent depth of the fish:

apparent depth = 50.0 cm / 1.33 = 37.6 cm

Answer:

Consider a satellite with mass Msat orbiting a central body with a mass of mass MCentral. The central body could be a planet, the sun or some other large mass capable of causing sufficient acceleration on a less massive nearby object. If the satellite moves in circular motion, then the net centripetal force acting upon this orbiting satellite is given by the relationship

Fnet = ( Msat • v2 ) / R

Explanation:

The acceleration of the satellite released from a spacecraft orbiting a planet at an altitude of 120 km and the planet has a mass of 5.2 x 10^23 kg and a radius of 2800 km is 4.426 *  \(10^6\)  \(m/s^2\).

The term "acceleration" refers to the rate and direction at which velocity varies over time. Acceleration is the change in direction or speed of an object or points moving ahead. The frequent change in direction causes motion on a circle to rise even when the speed remains constant.

For all other motions, these effects increase the acceleration. A vector quantity, acceleration, is something that has both a magnitude and a direction. Velocity is a vector quantity as well.

Given:

The altitude of the spacecraft, h = 120 km,

The mass of the planet, m = \(5.2 * 10^{23}\) kg,

The radius of the planet, r = 2800 km.

Calculate the acceleration by the formula given below,

A = \(G* m /r^2\)

Here, A is the acceleration, G is the gravitational constant,

Substitute the values,

A = 6.674 * \(10^{-11}\) *5.2 * \(10^{23}\) / \(2800^2\)

A = 4.426 *  \(10^6\)  \(m/s^2\)
