On a speed-versus-time graph, a straight line that slopes down toward
the right shows that the object is experiencing a constant deceleration.
Answer:
Explanation:
Intake heat, QH = 100 J
output heat, Qc = 20 J
Work, W = 80 J
TH = 100°C = 373 K
Tc = 10°C = 283 K
TH/ Tc = 373 / 283 = 1.318
QH/Qc = 100 / 20 = 5
for a heat engine, those ratios should be same. so temperature is not correct.
20 N , in +x direction is the vector sum of these Toro forces.
<h3>What is
force?</h3>
- The word "force" has a specific meaning in science.
- At this level, calling a force a push or a pull is entirely appropriate.
- A force is not something an object "has in it" or that it "contains."
- One thing experiences a force from another.
- There are both living things and non-living objects in the concept of a force.
- Force is used to describe a body's tendency to modify or change its state as a result of an external cause.
- When force is applied, the body can also alter its size, shape, and direction. kicking a ball, pushing and pulling on the door, or kneading dough are a few examples.
- The newton, abbreviated N, is the SI unit of force.
