Answer:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Explanation:
here this may help.
Answer:
Explanation:
We have the following information,
We apply the equation for capacitor charging the voltage across it,
Replacing values,
This would be the definition of gravitational force, I believe. The force of attraction between 2 objects based on the mass of the objects.
The weight of the object moving and the roughness of the surfaces
Answer:
The convective heat transfer coefficient of the fluid is 170.4 watts per square meter-degree Celsius.
Explanation:
The Nusselt number (
) is a dimensionless factor which compares the sensitivity of a fluid due to convection with those due to conduction:
(Eq. 1)
Where:
- Convective heat transfer coefficient, measured in watts per square meter-degree Celsius.
- Conductive heat transfer coefficient, measured in watts per meter-degree Celsius.
- Characteristic length, measured in meters.
In addition, the characteristic length of a cylinder is defined by the following formula:
(Eq. 2)
Where:
- Radius of the cylinder, measured in meters.
- Length of the cylinder, measured in meters.
If we know that 
, 
, 
and 
, then the convective heat coefficient is:
From (Eq. 2):
And by (Eq. 1):
The convective heat transfer coefficient of the fluid is 170.4 watts per square meter-degree Celsius.
