The Sun's heat is spread unevenly on Earth, and the atmosphere and oceans circulate and redistribute heat.
B. changes the direction of the satellite.
C. is a center-directed force.
D. all of the above
Answer : (D) " all of the above "
Explanation :
The forces acting on a satellite are Earth's gravitational force and centripetal force. The properties of centripetal force acting on a satellite in orbit are as follows :
(1) It acts as an unbalanced force on the satellite. This is due to the reason that there is no same force present which pulls the satellite away from the earth.
(2) It changes the direction of the satellite. The satellite is revolving with a constant speed while the direction is kept on changing (in a circular motion).
(3) Centripetal force always acts towards the center.
So, the correct option is (D) " all of the above "
b. radio wave.
c. microwave.
d. visible light wave.
Of the waves listed, the one with the longest wavelength is the radio wave. The answer is letter B. They are the longest wave in the electromagnetic spectrum. It can either be a long wave or a short wave.
The energy possess is 6,000,000 J
The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.
Given:
The mass of automobile is .
The velocity of the automobile is .
Write the formula to calculate the potential energy of the body.
Since the automobile is on ground so the height will be 0.
Write the formula to calculate the kinetic energy.
Substitute the value.
Learn more about potential energy and kinetic energy follow below link:
Answer:
6,000,000 J (6 million)
Explanation:
Refer to the equations for potential and kinetic energy.
Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0. If you plug in 0 for h in the potential energy equation, we get PE = 0 J.
Therefore, all of the energy is kinetic. Plug in the given information into the kinetic energy equation. M = 1200 kg and v = 100 m/s
