Answer:
B . 68.7 N
Explanation:
Given in the question that;
Force = 22 N
Mass = 7.0 kg
Velocity = 4.0 m/s
Gravitational force is the weight of wooden block , calculated as mass times acceleration due to gravity.
F= m* a
F= 7 * 9.81
F= 68.67 N
F= 68.7 N
The particles are either being absorbed or evaporating
Answer:
30600kg
Explanation:
density=m/v make v subject of the formula
Answer:
True
Explanation:
The heat trasnfer caused by the bulk movement of molecules of fluids is known as convection. Convection has two constituent process advection and diffusion. Examples of natural convection include atmospheric circulation, weather, oceanic circulation, mantle convection etc.
In forced convection the movement of fluid is caused by an external device (source). A fan, pump used to move fluid are external sources that cause fluid movement, the movement of fluid is not happening naturally.
