Answer:
Since a 100-N force is being used to push the crate in one direction, and there is a total net force of 0, the force of friction acting on the crate must also be 100 N. This frictional force points in the direction opposite of the push.
Answer:
Time, t = 141 seconds
Explanation:
Given that,
Distance between the class and the person, d = 282 m
Speed of the person, v = 2 m/s
We need to find the time taken by the person to get to your class. Let the time taken is t. The speed of the person is given by :
t = 141 seconds
So, the time taken by the person to get to your class is 141 seconds. Hence, this is the required solution.
FIRST STOP: EARTH'S ATMOSPHERE
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.
Yes because colored objects absorb heat and deflect the rest back to the sun unlike the the color white which reflects the rays of the sun completely thus making it appear white
