You are standing 10 meters from a light source. then, you back away from the light source until you are 20 meters away from it.

-Dominant- [34]

Intensity of wave is defined as the work per unit area and it is calculated through the equation,
I = P / A

If a person moved farther from the light source, the area covered by the light. With the equation, A is a inversely proportional to light. If the distance is to cover half of the team. The answer therefore, the intensity of the wave is lessened.

To be safe, the engineers making the ride want to be sure the normal force does not exceed 1.5 times each persons weight - and t

ANTONII [103]

Answer:

The minimum coefficient of friction is 0.666

Explanation:

Suppose, In a classic carnival ride, patrons stand against the wall in a cylindrical shaped room. Once the room gets spinning fast enough, the floor drops from the bottom of the room! Friction between the walls of the room and the people on the ride make them the “stick” to the wall so they do not slide down. In one ride, the radius of the cylindrical room is R = 7.6 m and the room spins with a frequency of 20.9 revolutions per minute.

Given that,

The normal force does not exceed 1.5 times each persons weight

$N=1.5 mg$

We need to calculate the minimum coefficient of friction

Using balance equation

$\mu N=mg$

$\mu=\dfrac{mg}{N}$

Where, N = normal force

Put the value into the formula

$\mu=\dfrac{mg}{1.5 mg}$

$\mu=\dfrac{1}{1.5}$

$\mu=0.666$

Hence, The minimum coefficient of friction is 0.666

What condition is required for cloud formation in the atmosphere?

Vedmedyk [2.9K]

Answer: To form a cloud, the air that rises must cool to the point where some of the water vapor molecules "clump together" at a faster pace than they are pulled apart by their thermal energy. These molecules then condense to form the clouds and water droplets.
