Answer:
The coefficient of static friction between your partner and the floor is 0.55
Explanation:
Given:
Mass
Kg
Frictional force
N
From the formula of frictional force,

Where
coefficient of static friction, 
Put the above values and find the coefficient of static friction.


Therefore, the coefficient of static friction between your partner and the floor is 0.55
Answer:
Their research differs because they were both talking about different things, Hayes was talking about how many lakes there were, while Malaska's was doing more hands on stuff like experiments. Both are important because we need to learn how the lakes formed, but we also need to do hands on experiments.

The amount of power change if less work is done in more time"then the amount of power will decrease".
<u>Option: B</u>
<u>Explanation:</u>
The rate of performing any work or activity by transferring amount of energy per unit time is understood as power. The unit of power is watt
Here this equation showcase that power is directly proportional to the work but dependent upon time as time is inversely proportional to the power i.e as time increases power decreases and vice versa.
This can be understood from an instance, on moving a load up a flight of stairs, the similar amount of work is done, no matter how heavy but when the work is done in a shorter period of time more power is required.
Answer:
Particles of matter are packed more tightly in the ground than in the air
Explanation:
the reason is that sound waves are vibrations of the molecules of the medium: therefore, if the particles of the medium are closer together (as in solids), the vibrations can be transmitted faster, and the wave can travel faster
