Answer:
Desert
Explanation:
The desert receives the least amount of rainfall yearly.
A desert can be described a barren area of land where little amount of rainfall occurs and, because of this, living conditions are not favourable for plants and animal life. Because there is no vegetation in a desert, the bare surface of the ground are subjected to denudation.
The acceleration and velocity of the plane is 78.57 m/s² and 157.14 m/s respectively
To calculate the acceleration of the plane, we use the formula below.
<h3>Formula:</h3>
- a = F/m..................... Equation 1
Where:
- a = Acceleration of the plane
- F = Force applied to the plane
- m = mass of the plane.
From the question,
Given:
Substitute these values into equation 1
- a = 550000/7000
- a = 78.57 m/s²
To calculate the velocity, we use the formula below.
- v = u+at............. Equation 2
Where:
- v = Final velocity
- u = initial velocity
- a = acceleration
- t = time.
From the question,
Given:
- u = 0 m/s
- a = 78.57 m/s
- t = 2.0 seconds
Substitute these values into equation 2
Hence, The acceleration and velocity of the plane is 78.57 m/s² and 157.14 m/s respectively.
