Answer:
City A will have a higher temperature overall than City B (D)
Explanation:
If all factors other than elevation are the same for both cities, then City A will have a higher temperature overall than City B. This is because there are fewer air molecules at higher elevations. Fewer air molecules mean less heat is absorbed by the atmosphere, and temperatures are lower. This is why areas high in the mountains are often much cooler than areas down on the plains.
For small deflections, T = 2*pi*sqrt(L / g) where T is period, L is length and g is gravity.
Setting the equations to the same period, 2*pi*sqrt(3.85 / g) = 2*pi*(L / (1/6 * g))
The equation reduces to 3.85 m = 6 * L so L = 0.642 m

Answer:
the ground when the ball hits it
Explanation:
A ball falls freely towards the Earth. If the action force is the Earth pulling down on the ball, then identify which of the following best describe the reaction force:
