Answer: The mountains that we observe on the moon, from earth are those rims forming the lunar mountains and mountain ranges. It has formed due to the asteroidal impact on the surface of the moon, billions of years back, resulting in the depressions and the highland areas. Due to this impact, a huge amount of heat energy generated that eroded and melted much of the materials from the moon's surface.

A concert loudspeaker suspended high off the ground emits 33.0 W of sound power. A small microphone with a 0.600 cm2 area is 52.
Novay_Z [31]

Answer:

The sound intensity at the position of the microphone is 9.71\times10^{-4} W/m^{2}

Explanation

Sound intensity is given by the formula

I=\frac{P}{A}

Where I is the sound intensity, P is the power and A is the area.

Since the loudspeaker radiates sound in all directions, we have a spherical sound wave where the radius r is the distance of the microphone from the speaker.

∴ A is given by 4\pi r^{2} where r is the radius

From the question, P = 33.0W, r = 52.0m

I=\frac{P}{A} = \frac{P}{4\pi r^{2} }

I = \frac{33.0}{4\pi \times (52.0)^{2} }

∴ I = 9.71\times10^{-4} W/m^{2}

Hence, the sound intensity at the position of the microphone is 9.71 × 10⁻⁴ W/m²

Which of the following is not a characteristic of the source of rivers and streams?
MrRa [10]
<span>The water is  clearer, has higher oxygen levels, and freshwater fish such as trout and heterotrophs can be found. In the middle of the river, the width increases, so do the species of  aquatic green plants and algae. Toward the mouth of the river, the water becomes murky from all the sediments that it has picked up upstream.<span>

When beavers inhabit an area, they cut down trees and construct beaver dams, which slow the flow of rivers or streams. Which of
Airida [17]

Answer: H

Explanation:

When beavers dam a stream they slow the movement of water. Behind the beaver dam, a pond of still water is formed. This pond is then colonized by animals and plants that typically live in lakes rather than streams.

The moon orbiting the Earth

Explanation:

The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.

  • A cannonball flying from a cannon is a projectile motion and not a circular motion.
  • A car moving along a straight track is a linear/translational motion.
  • Pendulum of a grandfather clock is a simple harmonic motion.
