I just took this test, the answer is 196 m^2, I got it right
Answer:
Better Equilibrium Maintenance for better accuracy...
Explanation:
In the Galileo's experiment, there is no utilization of two equal masses at a time. However, as we can see in a Atwood Machine, there are two equal masses involved that make the whole system to be in a state of equilibrium and ultimately the better measurements of acceleration due to gravity.
D.as a magnet is being thrust through the coil
Answer:
D. 200 kgm/s
Explanation:
Momentum is conserved.
Initial momentum = final momentum
(50 kg) (4 m/s) + (30 kg) (0 m/s) = final momentum
200 kgm/s = final momentum
