Force applied by the machine to over come resistance
Answer:
The pressure will be transmitted equally to all other parts of the confined fluid causing a general increase in pressure throughout the container.
Explanation:
This is in line with pascal's law of pressure which states that the pressure exerted on a given mass of fluid is transmitted undiminished to other parts of the fluid.
velocity = distance / time v= d/t firstly you change 3000 m into km distance D = 3000/1000 = 3 km secondly time t = 21 min using velocity formula v = d/t = 3 km/21min =0.142km/min
Answer:
- A book lying on a table - Balanced force
- An airplane cruising in level flight - Balanced
- A rock falling from a cliff - Unbalanced force
- A bridge collapsing in an earthquake - Unbalanced force
- A man sitting on a park bench - Balanced force
- A space shuttle taking off - Unbalanced force
- A car maintaining a constant speed on a straight road - Balanced force
- An airplane landing - Unbalanced force
Explanation:
Usually, one or more forces act on a body at an instant of time. When these forces acting on a body and bring the body in the equilibrium position, the force is said to be balanced. The unbalanced force changes the equilibrium state of the body.
As in the case of an airplane cruising in a level flight, the weight of the plane will be equal to the lift force and the thrust is equal to the drag. So the plane is experiencing a balanced force.
