Answer:

F = \frac{6.67408m_1 m_2}{10^{11}r^2}

Explanation:

Given

Object_1 = m_1

Object_2 = m_2

Distance = r

Required

Determine the force of attraction

This is calculated as:

F = \frac{GMm}{d^2}

Where

M = mass of object 1

m = mass of object 2

d = distance

Where G = gravitational constant

G = 6.67408 * 10^{-11}\ m^3 kg^{-1} s^{-2}

Substitute these values in

F = \frac{GMm}{d^2}

F = \frac{6.67408 * 10^{-11} * m_1 * m_2}{r^2}

F = \frac{6.67408 * m_1 * m_2* 10^{-11}}{r^2}

F = \frac{6.67408m_1 m_2* 10^{-11}}{r^2}

F = \frac{6.67408m_1 m_2}{10^{11}*r^2}

F = \frac{6.67408m_1 m_2}{10^{11}r^2}

A photon has a momentum of 5.55 x 10-27 kg-m/s. (a) What is the photon's wavelength? nm (b) To what part of the electromagnetic
Brrunno [24]

Explanation:

It is given that,

Momentum of the photon, p=5.55\times 10^{-27}\ kg-m/s

(a) We need to find the wavelength of this photon. It can be calculated using the concept of De-broglie wavelength.

\lambda=\dfrac{h}{p}

h is the Planck's constant

\lambda=\dfrac{6.67\times 10^{-34}\ Js}{5.55\times 10^{-27}\ kg-m/s}

\lambda=1.2\times 10^{-7}\ m

or

\lambda=120\ nm

(b) The wavelength lies in the group of ultraviolet rays. The wavelength of UV rays lies in between 400 nm to 10 nm.

A student does an experiment with a mirror. She measures the angle between the mirror and an incident ray and finds that it is 3
inessss [21]

If she measures the angle between the mirror and an incident ray and finds that it is 30°, then the angle of the incidence would be 60° and the angle of the reflection would be 60° as well because of the laws of the reflection.

<h3>What is the law of reflection?</h3>

The law of reflection states that when a ray of light reflects back from a surface the angle of incidence of light on a surface is equal to the angle of reflection.

As given in the problem statement A student does an experiment with a mirror. She measures the angle between the mirror and an incident ray and finds that it is 30°.

the angle of incidence = 90° - 30°

                                      =60°

As per the laws of the reflection

the angle of the incidence = angle of reflection

the angle of the reflection = 60°

Thus, the angle of the incidence would be 60° and the angle of the reflection would be 60° as well.

Why does a rocket continue to rise after it runs out of fuel
Darina [25.2K]

Answer: The surface of the pad pushes the rocket up while gravity tries to pull it down. As the engines are ignited, the thrust from the rocket unbalances the forces, and the rocket travels upward. Later, when the rocket runs out of fuel, it slows down, stops at the highest point of its flight, then falls back to Earth.
