OPTIONS :
A.) the force that the ball exerts on the wall
B.) the frictional force between the wall and the ball
C.) the acceleration of the ball as it approaches the wall
D.) the normal force that the wall exerts on the ball
Answer: D.) the normal force that the wall exerts on the ball
Explanation: The normal force acting on an object can be explained as a force experienced by an object when it comes in contact with a flat surface. The normal force acts perpendicular to the surface of contact.
In the scenario described above, Erica's tennis ball experiences an opposite reaction after hitting the wall.This is in relation to Newton's 3rd law of motion, which states that, For every action, there is an equal and opposite reaction.
The reaction force in this case is the normal force exerted on the ball by the wall perpendicular to the surface of contact.
The correct answer is tissue.
Compression wrapping is used to reduce swelling and assists with sprains and wounds. If the wrap is applied wrong then this can cause impairment in circulation in the skin, it can cause an abnormal amount of swelling and irritate the skin. Therefore it seems likely that the answer would be tissue.
Answer:
Magnitude of y-component=7 units
Direction= angle of vector A with x-axis=
Explanation:
Explained solution is in the picture attached
The potential energy of the charges due to the voltage between the terminals is converted to kinetic energy in the device. These devices are called passive components or loads; they 'consume' electric power from the circuit, converting it to other forms of energy such as mechanical work, heat, light, etc.
Answer:
Displacement = 4000 m
Explanation:
Given that,
Each lap is 1000 m.
David completes 4 laps of his complex
We need to find David's displacement. In n laps, the net displacement is n time of distance covered.
Displacement = 4 × 1000
= 4000 m
Hence, Davis's displacement is 4000 m.
