5.00 N
1440 N
1490 N
A nurse applies a horizontal force of 147 N on a bed that has a mass of 152 kg. The magnitude of the normal force acting on the bed is 1490 N.
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
The force applied by the nurse is horizontal, so there's no vertical component.
Therefore, the normal force is simply equal to the weight of the bed.
N = mg
N = (152 kg) (9.8 m/s²)
N = 1490 N

Answer:
1490 N
Explanation:
The force applied by the nurse is horizontal, so there's no vertical component.
Therefore, the normal force is simply equal to the weight of the bed.
N = mg
N = (152 kg) (9.8 m/s²)
N = 1490 N
Answer: the correct answer is 8*10^-11
B) The magnitude of gravitational forces is greater than the magnitude of electromagnetic forces.
C) The magnitude of electromagnetic forces is always equal to the magnitude of reaction forces.
D) The magnitude of gravitational forces is always equal to the magnitude of electromagnetic forces.
Answer:
The magnitude of electromagnetic forces is greater than the magnitude of gravitational forces.
Explanation:
There are four fundamental forces in nature. These are as follows :
(1) Gravitational force
(2) Electromagnetic force
(3) Weak force
(4) Strong force
Gravitational force is the weakest force among all the fundamental forces. The gravitational force exists between masses present in the universe while the electromagnetic force exist between charged particles. The magnitude of gravitational force is weaker than the electromagnetic force. It is about times more than gravitational force.
Hence, the correct statement about forces in the solar system is (A).
