Answer:
.17Hz
Explanation:
The formula for frequency is f= 1/T , where T is the period.
f = 1/6 and 1/6 ≈ .17
Answer:
Explanation:
Recall that in this case, friction is not taken into account. Thus, Using the free body diagram, according to Newton's second law, we have:
For the lighter block:
For the heavier block:
The acceleration is the same for both blocks:
So, replacing (2) in (1):
Answer:
gravitational potenetial energy =ℎ
Explanation:
none
Answer:
e. Evaporation affects land more than ocean surfaces.
Explanation:
Land warms faster than water. Since the kinetic energy of a molecule is proportional to its temperature, evaporation occurs faster as the temperature is higher. As the molecules that move faster escape, the remaining molecules have a lower average kinetic energy, and therefore the temperature of the liquid decreases.
