Answer:
Explanation:
The force of gravity acting on the satellite is given by:
where
G is the gravitational constant
is the Earth's mass
m is the mass of the satellite
r is the distance of the satellite from the Earth's centre
Here we have
m = 700 kg
Substituting into the equation, we find:
<em>Note that the distance mentioned in the problem (2.4 x 10^6 meters) is not realistic, since it is less than the radius of the Earth (6.37 x 10^6 meters).</em>
The answer is False, pls. mark me the brainliest if I’m right. THX
Boiling. The temperature at which a liquid begins to boil is called the <span>boiling point.</span>
It is possible because the rubber ball has mechanical energy which is equal to potential energy.
<h3>
What is mechanical energy?</h3>
Mechanical energy of an object is the total energy possessed by the object, including the potential energy and the kinetic energy.
M.A = K.E + P.E
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy possessed by an object due to its motion.
<h3>What is potential energy?</h3>
Potential energy is the energy possessed by an object due to its position.
When kinetic energy (K.E) = 0
M.A = P.E
Thus, it is possible because the rubber ball has mechanical energy which is equal to potential energy.

Answer: 1100 ft lb/s and 2 H.P
Explanation:
To calculate for the power developed in the elevator motor in ft.lb/s, we multiply the distance and the weight of the elevator and divide the product by the time.
Power = (10 ft)(2200 lb) / 20 s = 1100 ft.lb/s
Next, convert the calculated value to HP.
1100 ft.lb/s x (1 HP/ 550 ft.lb/s) = 2 HP
hope this helps please give brainliest!
