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:
Explanation:
See the file attached .
b ) Range of projectile
= u²sin2θ / g
= 42² sin32 x 2 / g
= 42² sin64 / 9.8
= 161.8 m
c )
Max height = u² sin²32 / 2 g
= 42² sin²32 / 2x 9.8
= 25.27 m .
Sigmund Freud would say he's employing a defense mechanism called displacement. It is an oblivious barrier component whereby the mind substitutes either another point or another question for objectives felt in their unique shape to be unsafe or inadmissible. The dislodging works in the psyche unknowingly, its transference of feelings, thoughts, or wishes being regularly used to alleviate uneasiness even with forceful or sexual motivations.
Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.
Let me know if this helps!
The correct answer is "True."
Further Explanation:
When a person first sees someone they are interested in they may have feelings of infatuation. When a person feels this they may believe it is love, but it is a significant level of the dopamine and norepinephrine that is being released into the brain.
After a while, when the infatuation subsides, the person may not have the same feelings as before since the levels have subsided. These substances control several emotions in the brain such as cravings for food, desires, and even a person's motivation.
