Answer:
There is much more friction on the rough surface than there is on the smooth surface.
Explanation:
We want to calculate the distance covered by the drag racer. Recall, the formula for calculating distance is expressed as
Distance = speed x time
From the information given,
speed = 320 m/s
time = 4.5 s
By substituting these values into the formula, we have
Distance = 320 m/s x 4.5s
s cancels out. We are left with m. Thus,
Distance = 1440m
The rate of change of vertical pressure is directly proportional to density and also directly proportional to temperature.
Generally, the relationship between temperature, density and rate of vertical pressure is given as;
where;
- <em>ρ is density</em>
- <em>T is temperature</em>
- <em>dP is rate of change of vertical pressure</em>
Thus, from the formula above, we can conclude the following relationship between temperature, density and the rate of vertical pressure change in spatial pattern of heights.
The rate of change of vertical pressure is directly proportional to density and also directly proportional to temperature.

This is the photoelectric effect, and it is best explained by the particle model of light.
<h3>What is the photoelectric effect?</h3>
The photoelectric effect refers to the emission of negatively charged particles and electromagnetic radiation that hits an object.
The photoelectric effect shows how electrons can be released from a given object when this material is absorbing electromagnetic radiation.
The photoelectric effect is a fundamental piece of evidence for understanding the nature of light particles.
