Mechanical Advantage= output force/input force. So, 156/52=3. You're MA is 3.
Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely.
V = 1/2at^2
a = 9.8 m/2^2 (constant)
t = 4.0 s
1/2 • 9.8 • 4^2
1/2 • 9.8 • 16
= 78.4 m/s
The unit of acceleration would be m/s² :)
Answer:
the electrical charge would be -4
