Answer:
Increasing the speed of an object decreases its motion energy. Increasing the speed of an object increases its motion energy. Increasing the speed of an object does not affect its motion energy. Whether or not its motion energy is affected depends on how much its speed was increased.
Explanation:
Answer:
-30=5(x+1) is -7
Explanation:
distribute flip subtract 5 from both sides divide both sides by 5
Answer:
Explanation:
1. An ideal ammeter has very small or almost zero resistance. As the resistance is small the maximum current can pass through the ammeter which it can read it.
2. An ideal voltmeter has very large or infinite resistance. As the resistance is very large so the maximum voltage drops across the resistor and gives the accurate reading.
d. both a and b
Explanation:
Seismic waves are both transverse and compressional or longitudinal waves.
A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.
- Seismic waves are both longitudinal and transverse waves.
- There are two main types of seismic waves which are the surface and body waves.
- The surface waves runs on the earth surface. These are the rayleigh and love waves.
- The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
- Body waves moves within the earth surface. They are p-waves and s-waves.
- P-waves are longitudinal or compressional waves that propagates within the earth surface.
- S-waves are transverse waves that moves perpendicularly to their direction of propagation.

Answer:
<h2>To solve typical questions like this we can use law of conversation of linear momentum...which is</h2>
<h2>T.I.L.M.=T.F.L.M.</h2>
(Total initial linear momentum = total final linear momentum.)
<u>Momentum = mass × velocity</u>
<h2>T.I.L.M = T.F.L.M</h2>
180×4 + 120×0 = 180×0 + 120×V
(180 ×4)/120 = V
<h2>6Ms^-1 = v</h2>
