Answer:
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Answer: 0.522 m
Explanation:
This situation is related to projectile motion, where the initial velocity of the car has only the horizontal component. This means the angle is equal to zero (). And the equations we will use to find the height of the cliff are:
(1)
Where:
is the final height of the car
is the initial height
is the initial velocity of the car
is the time
is the acceleration due to gravity
is the angle
is the horizontal distance traveled by the car after passing the cliff
Well, firstly we have to find from (1):
(3)
(4)
Substituting (4) in (2):
(5)
Isolating :
(6)
(7)
Finally:
Typically two copies in each cell.
Answer:
Increase.
Explanation:
The force between two charges is given by :
Where
k is electrostatic constant
d is the distance between two charges
The force is inversely proportional to the distance between charges. It means when the distance between two charges decreases, the electric force will increase. Hence, the correct option is (c) "increase".
In this case W is negative, the heat input is less than in the constant volume case, and CP is less than CV. If the ice melts it is as if it were being compressed because its volume is reduced.
