Answer:
there are conversion scales used for doing that
to convert Celsius to Fahrenheit we use the formula,
T(°F) = T(°C) × 9/5 + 32
and to convert Fahrenheit to Celsius we use,
T(°F) = T(°C) × 5/9 + 32

Explanation:
The average velocity is obtained by ( u + v)/2.
<h3>What is average velocity?</h3>
The term velocity refers to the rate of change of displacement with time. Velocity is a vector quantity thus it has both magnitude and direction. The velocity of a body could also be shown by the use of the vector notation.
To obtain the average velocity;
Let the initial velocity be u
Let the final velocity be v
It then follows that the average velocity = ( u + v)/2

Answer:
The work done by the weightlifter, W = 700 J
The power of the weightlifter, P = 350 watts
Explanation:
A weightlifter lifts a set of weights a vertical distance, s = 2 m
The force exerted to lift the weight, F = 350 N
The work done by the body is defined as the product of the force applied by the body to the displacement it caused.
W = F x s
= 350 N x 2 m
= 700 J
The work done by the weightlifter, W = 700 J
The time taken by the weightlifter to lift the weight, t = 2 s
The power is defined as the rate of body to do work. It is given by the equation,
P = W / t
= 700 J / 2 s
= 350 watts
Hence, the power of the weightlifter, P = 350 watts
