Answer:
i think c
Explanation:
because cars run on mechanical energy and solar powered means its by the sun which is light energy
Elements with the largest atomic radius are found in the lower left hand of the periodic table.
Answer:
a.) F = 3515 N
b.) F = 140600 N
Explanation: given that the
Mass M = 74kg
Initial velocity U = 7.6 m/s
Time t = 0.16 s
Force F = change in momentum ÷ time
F = (74×7.6)/0.16
F = 3515 N
b.) If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0080 seconds
Change in momentum = 74×7.6 + 74×7.6
Change in momentum = 562.4 + 562.4 = 1124.8 kgm/s
F = 1124.8/0.0080 = 140600 N
A geocentric system is a part of the astronomical theory which describes the universe. Meaning that it puts the Earth in the CENTER of the universe as a point of view for other objects surrounding it.
Conservation in this case means that it doesn't change. Momentum isn't created or destroyed, but it remains constant.
