Your answer is friction. Friction between to object slows the object down.
Answer: h = 0.30 m
Explanation:
A person jumping from height h would possess potential energy = m g h
which will convert completely into kinetic energy as person hits the ground. Now, the maximum energy absorbed by the person can be = 200 J
m = 67 kg
g = 9.8 m/s²
⇒ m g h = 200 J
⇒ h = 200 J / (67 kg × 9.8 m/s²) = 0.30 m
Hence, a person can land safely on both legs without breaking them from a height of 0.30 m only.
Fluids always transfer heat by convection. So, your answer is B. That's how a oven works actually!
The simplest arrangement of a reflex arc consists of the receptor, an interneuron (or adjustor), and an effector; together, these units form a functional group. Sensory cells carry input from the receptor (afferent impulses) to a central interneuron, which makes contact with a motor neuron.
Using the formula,
Here, d is distance, v is the velocity and t is time.
Given, 
and 
.
Substituting these values in above formula, we get
Thus, the distance traveled by the car is 200 miles
