Answer:
Thickness of Styrofoam insulation is 0.02741 m.
Explanation:
Given that,
Height = 0.25 m
Depth = 0.5 m
Power = 400 W
Temperature = 33°C
We need to calculate the area of Styrofoam
Using formula of area
Put the value into the formula
Inner surface temperature of freezer
Outer surface temperature of freezer
We need to calculate the thickness of Styrofoam insulation
Using Fourier law,
Put the value into the formula
Hence, Thickness of Styrofoam insulation is 0.02741 m.
The force applied on the football is 2.15 Newton.
Given the data in the question;
- Mass of football;
- Acceleration;
Force applied;
To determine the force applied on the football, we use Newton's laws of motion:
Where m is the mass of the object and a is the acceleration.
We substitute our given values into the equation
Therefore, the force applied on the football is 2.15 Newton.
