Explanation:
Let's say right is positive and left is negative.
F₁ = -150 N
F₂ = 220 N
Fnet = F₁ + F₂
Fnet = -150 N + 220 N
Fnet = 70 N
The magnitude of Fnet is 70 N, and since it's positive, the direction is to the right.
And since Fnet isn't 0, the force is unbalanced and the motion is changing.
Answer:
Explanation:
Given that,
The mass of the paperclip, m = 1.8 g = 0.0018 kg
We need to find the energy obtained. The relation between mass and energy is given by :
Where
c is the speed of light
So,
So, the energy obtained is 
.
The branch of physics that deals with the study of force energy and motion is classic mechanics

An example of a a predator in the Ethiopian Highlands ecosystem is the
Wolf.The wolf is a carnivore which acts as a predator to other smaller
animals in the ecosystem.
<h3>What is a Prey?</h3>
Preys are mostly smaller animals in which the predators feed on for food.
They are usually herbivores and primary consumers in the ecosystem.
Examples of Preys include:
