Answer:Newton's three laws of motion relate to each other in that they lay a foundation for the principles of things in motion, then build upon that foundation. For example, the first law of motion,...

Answer: Hello! An objects speed is constant and has the units meters per second (m/s); thus, it does not change overtime. Acceleration is a rate of change where the speed does either increase or decrease overtime from its inital value; its units are meters per second second (m/s/s). I hope that helps!
The phase of the Moon must be new, and the nodes of the Moon's orbit must be nearly aligned with Earth and the Sun.
C according to my calculations
Answer:
Power = 30 [watts]
Explanation:
Initia data:
F = force = 30[N]
d = displacement = 2 [m]
By definition we know that work is equal to the product of force by the distance displaced
Therefore:
W = F * d = 30 * 2
W = 60 [J]
And power is defined as the amount of work done in a given time interval
time = t = 2 [sec]
Power = W / t
Power = 60 / 2
Power = 30 [W]
