The answer is True. The amount force exerted by any object is directly proportional to its mass. This means that our planet is exerting more gravitational force to Angelina, and Angelina is also exerting a gravitational force on our planet directly proportional to her mass. Angelina is actually falling towards the center of the earth,and also our planet is also moving towards Angelina, but it seems negligible with respect to Angelina.Our Sun is so massive that it held our planet in its orbit because of its gravitational force.
Voltage= current*resistance or V=IR
so V=18*12= 216 volts
Answer:
0
Explanation:
The bicyclist is not speeding up or slowing down so there is no acceleration.
Answer:
The total mechanical energy of a simple harmonic oscillating system is Constant
Explanation:
During the movement of an object in simple harmonic motion, the total mechanical energy is constant
The total mechanical energy is given by 
By the conservation of energy principle the energy in the simple harmonic motion transforms between kinetic and potential energy while maintaining a constant sum
Answer:
Angle of twist;Φ = (to•L²)/Gπc⁴
Explanation:
I have attached the explanation.
However, I used D for radius of shaft against c used in the question. So, if we replace the D with c, we'll have;
Φ = (to•L²)/Gπc⁴
