Krista is playing tennis at the park. When the tennis ball flies toward her, Krista hits the ball with her racket, which causes

the ball to fly in the opposite direction. According to Newton's third law of motion, which of the following is true?A. When the racket hits the tennis ball with a force, the ball does not apply any reaction force to the racket.
B. When the racket hits the tennis ball with a force, the tennis ball applies an equal but opposite force to the racket.
C. When the racket hits the tennis ball with a force, the ball applies a much weaker force in the opposite direction of the racket's force.
D. When the racket hits the tennis ball with a force, the ball applies an equal force in the same direction as the racket's force.

Answer:

B. When the racket hits the tennis ball with a force, the tennis ball applies an equal but opposite force to the racket.

Explanation:

According to the Newton's third law of motion every action has equal and opposite reaction. So, when the force is applied by the racket on the ball then the ball also applies an equal intensity of force in the opposite direction on the racket. It is just that the the force on the racket is absorbed by the player holding it.

A potentialiterence of 12 volts is induced across a straight wire 0.20 meters long as it is moved at a constant speed of 3.0 met
shtirl [24]

Strength of the magnetic field: 20 T

Explanation:

For a conductive wire moving perpendicular to a magnetic field, the electromotive force (voltage) induced in the wire due to electromagnetic induction is given by

\epsilon=BvL

where

B is the strength of the magnetic field

v is the speed of the wire

L is the length of the wire

For the wire in this problem, we have:

\epsilon=12 V (induced emf)

L = 0.20 m (length of the wire)

v = 3.0 m/s (speed)

Solving  for B, we find the strength of the magnetic field:

B=\frac{\epsilon}{vL}=\frac{12}{(0.20)(3.0)}=20 T

Which of the following, if eliminated, would completely prevent the greenhouse effect from occurring on earth?
DochEvi [55]

The green house gases can be reduced up to a limit by eliminating the fossil fuels and chlorofluorocarbons. Fossil fuels are the major source of greenhouse gases.

<h3>What are green house gases?</h3>

Greenhouse gases are those which are capable of  intense absorption of  the temperature  radiated from the earth's surface and make the earth atmosphere warm up.

Greenhouse gases are the main cause of global warming.  Carbon dioxide, methane oxides of nitrogen and sulphur are the green house gases.

Fossil fuels are rich in hydrocarbons and they release these gases when  burned. Mainly methane and other hydrocarbon gases intensely absorbs the temperature which is radiating away from the earth and thus the heat is trapped inside.

Therefore, by eliminating fossil fuels, greenhouse effect can be prevented.
