Answer:
The car's average speed is 16 feet per second.
Explanation:
The expression for the average speed is as follows;
Given expression of distance:
Put t= 4 s.
d(4)= 36 ft
Put t= 7 s in the given expression.
d(7)= 84 ft
Calculate the car's average speed over the interval of time from t = 4 seconds to t = 7 seconds.
A.S= 16 feet per second
Therefore, the car's average speed is 16 feet per second.
Answer:When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
Explanation:
The units of pressure are called derived units because it is derived from base unit, which is distance and a derived unit which is force. Force is derived from acceleration, a derived unit as well, and mass, a base unit; which makes it a derived unit.
It is the second provided answer.
Speed is the change in distance over time; velocity is speed plus direction.
