# What is the general assembly of the united nation?  wavelength- 1st

frequency- 7th

energy- 7th

Explanation:

because wavelength and frequency are indirectly proportional with each other while frequency and energy and directly proportional with each other Hello!

What is the formula of universal gravitation ?

We have the following data:

F (gravitational force between two bodies) = (measure in Newton)

G (Universal gravitation constant) = m1 and m2 (mass of bodies) = (measured in kilograms)

d (distance between the centers of the bodies) = (measure in meters  )

Formula: _______________________  Good Day

Problem:

The acceleration of gravity on the moon is 1.62 m/s square.If a ball is dropped on the moon from a height of 1.5 m,determine the time for the ball to fall to the surface of the moon​

Given Data:

a (acceleration due to gravity) = 1.62 m/s²

d (distance)   =   1.5 m

Vi (initial velocity) = 0 m/s

t (time)  = ?

Solution:

we can use the formula, d = 1/2at² since Vi = 0 m/s

To solve for t, we can use, t = √ d/ 1/2a

t = √ d/ 1/2a

= √1.5 / 1/2(1.62 m/s²)

= √1.5 m / 0.81 m/s²

= √ 1.85 s²

= 1.36 seconds

Time is 1.36 seconds once it reaches our solar system it will get pulled by the sun like a slingshot and as it gets closer to the sun its velocity will increase and its orbit's trajectory will be changed and as it gets farther from the sun its velocity decreases  ### Another question on Physics Physics, 28.10.2019 23:29
