An 8.30 kg crate is pushed with a 17.7 N force. How fast does it accelerate?
kramer

Answer:

2.13m/s^2

Explanation:

Use equation:

Fnet=ma

If 17.7 is the netto force (Fnet) then you just substitute the values in and solve.

Note m is mass (kg) and a is acceleration (m/s^2)

When a third object is brought in contact with the first object (after it gains the electrons), the resulting charge on the thir
nirvana33 [79]

Answer:

- Contact 1 with 3 ,  initial charge of 1.8 C.

- contact 1 with 2 and then 1 with 3 , first body should have 3.6 C

Explanation:

The excess charge on a body is distributed evenly throughout the body.

We can have two different configurations:

- Contact 1 with 3

When the third body was touched with the first, the initial charge was distributed between the two, so that when each one separated, it had half the charge, in this configuration the first body should have an initial charge of 1.8 C.

- contact 1 with 2 and then 1 with 3

Another possible configuration of the exercise is that the first body touches the second and the charge decrease to the half and then touches the third where it again decreases by half, so that the first body only gives it every ¼ of its initial load.

Therefore in this configuration if the third body has a load of 0.9C the first body should have 3.6 C

Lunna [17]

Answer:B. The superposition of waves from the primary source and reflected waves produced regions of constructive and destructive interference.

Explanation: Tsunami is described as several waves originating from a water body mainly an ocean caused by Large scale earth movements taking place under the sea.

Superimposition of wave is the movement of one wave on another,it can be constructive or destructive.

Constructive interference is a wave interference that take place causing the Crest of one wave to align with that of another wave leading to high amplitude.

Destructive interference is a wave interference that take place causing the Trouph of one wave to align with the crest of another wave leading to low amplitude wave.
