<span>The period of a satellite in a circular orbit can be obtained by using the formula below:

P = √(4π²r³/GM)

Where: constant GM of the Moon (gravity * mass) = </span><span>4.903x10^12 m³/s²

Substituting and simplifying:

</span><span>P = 2.838x10^(-6) * √(1.738x10^6)³
</span>P = 6502 seconds, or 108.37 minutes

A 0.75 kilogram apple is thrown upward from the ground. The apple reaches a height of 5.5m, what is the beginning gravitational
MaRussiya [10]

Answer:

U(0.0m) = 0J

U(5.5m) = 40.42 J

Explanation:

The gravitational potential energy is given by the following formula:

U=mgh

h: height

m: mass of the apple = 0.75kg

g: gravitational acceleration = 9.8m/s^2

When the apple is at 5.5m from the ground the gravitational potential energy is:

U=(0.75kg)(9.8m/s^2)(5.5m)=40.42\ J

when the apple is on the ground you have:

U=mg(0m)=0\ J

What is the best way to avoid being run over by your own pwc or motorboat?
kobusy [5.1K]
Wear an ignition safety switch lanyard so you can turn it off. Most powerboats and PWCs come furnished by the maker with a crisis motor cut-off switch. This wellbeing gadget can stop the motor if the administrator tumbles off the PWC or out of the powerboat, or is generally tossed from the best possible working position.

Sonar is a device that uses reflected sound waves to measure underwater depths. If a sonar signal has a frequency of 288 Hz and
mart [117]

Answer:

5.03 m

Explanation:

The wavelength of a wave is given by

\lambda=\frac{v}{f}

where

v is the speed of the wave

f is the frequency of the wave

For the sonar signal in this problem,

f=288 Hz

v=1.45\cdot 10^3 m/s

Substituting into the equation, we find the wavelength:

\lambda=\frac{1.45\cdot 10^3 m/s}{288 Hz}=5.03 m
