1. Just like vitamins, minerals help your body grow, develop, and stay healthy. The body uses minerals to perform many different functions, from building strong bones to transmitting nerve impulses. Some minerals are even used to make hormones or maintain a normal heartbeat.
2. Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.
Hope this helps.
The distance is 97720.5 m
From the question, we have
P = 0.06 W × 2 = 0.12 W
d = ?
Sound intensity, I = P/4πd²
I = 10⁻¹² W/m²
10⁻¹² = 0.12/4πd²
d = 97720.5 m
The distance is 97720.5 m
Sound intensity :
The power carried by sound waves per unit area in the direction perpendicular to that region is known as sound intensity or acoustic intensity. The watt per square meter (W/m2) is the SI unit of intensity, which also covers sound intensity. Sound intensity is a measure of how quickly energy moves across a given space. The unit area in the SI measurement system is 1 m2. So Watts per square meter are used to measure sound intensity. As there will be energy flow in certain directions but not in others, sound intensity also provides a measure of direction.

Answer:
Decrease of snake, coyote, and hawk population. Increase of sagebrush and cacti.
Reasons:
The rats are aten by the snake coyote and hawks so if a food source is taken from them they are going to have to fight more for food. The rats eat the sagebrush and cacti so if they arent getting eaten as much, they have mroe ime to produce.
Answer:
Explanation:
Given:
- Linear horizontal speed of the ball,
- distance travelled by the ball,
- angle rotated by the ball,
- radius of the ball,
<u>the time for which the ball travels:</u>
<u>Angular speed of the ball:</u>
<u>Now the tangential speed at the equator of the ball:</u>
(the tangential speed due to rotation and the linear speed are having the same direction)
