Answer:
The answer to your question is 1800 Pa
Explanation:
Data
Weight = 2700 N
Area = 1.5 m²
Pressure = ?
Formula
Pressure = Force / Area
The Pressure is defined as the force exerted per unit area.
-Substitution
Pressure = 2700 / 1.5
-Result
Pressure = 1800 Pa
The units of pressure are Pascals (Pa)
Answer:

Explanation:
Given that


Emissivity of surfaces(∈) = 1
We know that heat transfer between two surfaces due to radiation ,when both surfaces are black bodies

So now by putting the values



So rate of heat transfer per unit area
