The atmosphere<span> can be </span>divided into<span> four </span>layers<span> based on temperature variations. The </span>layer<span> closest to the Earth is called the troposphere. Above this </span>layer<span> is the stratosphere, followed by the mesosphere, then the thermosphere.</span>
The time it takes for a point to reach 0 displacement from maximum displacement is
of a cycle. Thus, one period (
) will take
.
The frequency is simply
.
The speed is given by:
Answer:
The power of sports car is 25 times power of older model car
Explanation:
Consider mass of the two cars are same and is denoted by m.
Kinetic energy of older model car is determine by the relation:
Kinetic energy of sports car is determine by the relation:
....(1)
Power is defined as energy per unit time.
According to the problem, the car has only kinetic energy. So, the power of old model and sports car are determine by the relation:
and
Here P₁ and P₂ are the power of old model and sports car respectively.
The ratio of power of these car is:
Substitute equation (1) in the above equation.
Let's convert the speed of the winds into SI units.
We know that
1 miles = 1609 m
1 hour = 3600 s
So, the velocity written in m/s is
