Answer:
A. both fields use the same technology
Explanation:
Net force is an unbalanced force, so the object will change speed or direction.
Either the object may speed up or slow down.
Answer:
Care giving tools like medical devices or any medical supplies which aid the effectiveness of care for the patient will help the quality of work of care giving. ... All of the care giving tool should also be efficient and effective
Explanation:
Given parameters:
Force applied = 150N
Time = 2s
Unknown:
Momentum change = ?
Solution:
The momentum change of a body is the difference between its initial and final momentum.
Momentum is the same as the impulse exerted on a body which is the product of force and time
Momentum = mass x velocity = force x time
The body initially at rest has a momentum of 0, as the momentum changes;
Momentum change = Final momentum - initial momentum
= f x t - (0)
= (150 x 2) - 0
Momentum change = 300kgm/s
Since the body is a frictionless surface, the net force is the same as the applied force.

Answer:
force is of the LINEAR type
Explanation:
In simple harmonic movements the restoring force is of the Hooke e-force type, which has the form
F = - k (x-x₀)
where x₀ is the initial length of the spring.
Therefore we can see this force is of the LINEAR type
