A change in the position of a body with respect to time relative to a reference point is motion.
Because there is no absolute point of reference, there is no true discernible absolute motion, and therefore, everything is said to be moving constantly.
Hope that helped =)
Answer:
C
Explanation:
Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.
Answer:
360 km/h
Explanation:
Velocity =Distance/time ⇒ distance = velocity×time
Distance for 1st 2 h = 400×2 = 800 km
Distance for next 1 h = 300×1 = 300 km
Distance for last 2 h = 350×2 = 700 km
Therefore total distance traveled = 1800 km
So average speed = 1800/5 = 360 km/h
The answer is DC power had to be converted in AC.
DC power is not usually in home. DC current must be converted to to AC, which is the standard in homes and to avoid short circuits.
DC or direct current explains the basic idea of electricity as a flow of electrons.
AC, also known as alternating current, electricity switches direction around 50-60 times each second. In here, electrons do not necessarily have to run in circles to transport energy, they simply run on the spot.
