Answer:
Time elapsed
Explanation:
Acceleration is a vector quantity. It is defined as:

where
v is the final velocity
u is the initial velocity
t is the time elapsed
Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:
- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity
- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity
Answer:
The thermal power emitted by the body is 
The net power radiated is 
Explanation:
From the question we are told that
The length of the assumed hum
an body is L = 2.0 m
The circumference of the assumed human body is 
The Stefan-Boltzmann constant is 
The temperature of skin 
The temperature of the room is
The emissivity is e=0.6
The thermal power radiated by the body is mathematically represented as

substituting value


The net power radiated by the body is mathematically evaluated as

Where A is the surface area of the body which is mathematically evaluated as

substituting values


=> 
=> 
A 1000J or 1kJ of energy in 1 second implies that in 1 minute there will be 60kJ of energy converted.
Work is the defined as energy consumed thought time.

In our case,

Hope this helps!
