Energy is transferred.
<h3>What is Work?</h3>
Every time labour is performed, energy is transmitted, as shown by the definition of work in physics. Work is the result of the displacement's magnitude and the component of force acting in that direction.
What are 3 types of work done?
- Positive
- Negative
- Zero work done.
Work is the result of force and distance, or the force exerted over a specific distance. In other words, Work = Force x Distance.
Joules are used to measure work.
1. Positive Work: Positive work is when a force moves an object in that direction. The motion of a ball descending toward the earth while it is displaced in the direction of the force of gravity is an illustration of this type of labour.
2. Negative Work: The work is said to be negative if the force and the displacement are in the opposing directions. For instance, if a ball is thrown high, its displacement will also be upwards, while the force from the earth's gravity will be downward.
3. Zero Work: When the force and displacement directions are parallel to one another, there is no work done on the item by the force.

Answer:
The green car traveled a shorter distance, but the displacement of the cars was equal.
Explanation:
Explanation:
sexual reproduction provides genetic diversity because the sperms and the egg that are produced contain different combination of the genes than the parent organisms so in order to from a new organisms two gamete the sex cells sperm and egg must fuselage further mixing the gene to produce more genetic diversity

Explanation:
Let , be the horizontal and vertical components of velocity.
Question a:
Horizontal component of velocity is the ratio of range and time of flight.
So,horizontal component of velocity is
So,
Question b:
Time of flight=
So,
Maximum height is given by
So,maximum height is
Question c:
The vertical velocity is already calculated in Question b.
