what occurs when force is applied over a certain distance and motion is in the same direction as the force?

2 answers:

8 0

An object in motion will continue to move in the same direction and with the same speed unless acted upon by an unbalanced force. states that forces occur as equal and opposite pairs. The strength of the force is related to the mass of the objects and the distance between them.

When force is applied over a certain distance and motion is in the same direction as the force, then you have a simple case of "WORK" being done, as it's defined in Physics.

The amount of work done in this case is (the force) multiplied by (the distance).

If the force is measured in Newtons and the distance is measured in meters, then the product has the units of Joules (energy).

When waves superimpose and make bigger amplitudes what form of interference is that

eimsori [14]

Answer:

Constructive Interference

Explanation:

Constructive Interference occurs when two waves superimpose and make bigger amplitudes.

In constructive interference, the crests of one wave fall on the crests of second wave and the amplitudes add up. The amplitude of the resultant wave is equal to sum of the amplitude of the individual waves. Similarly, the trough of first wave falls on the trough of other wave and they superimpose to create the trough of the resultant wave.

For Example, In the attachment, two waves A and B superimpose and demonstrate Constructive interference to create the wave C.

The moon orbiting the Earth

Explanation:

The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.

A cannonball flying from a cannon is a projectile motion and not a circular motion.
A car moving along a straight track is a linear/translational motion.
Pendulum of a grandfather clock is a simple harmonic motion.

A heat engine exhausts 3 000 J of heat while performing 1 500 J of useful work. What is the efficiency of the engine

amid [387]

efficiency=work output/work input×100

since it exhausts(use up)3000j of heat that's the work input and the 1500j is the work input

efficiency=1500/3000×100

=50%
