6 cubic feet I’m pretty sure that’s the answer
A
longitudinal wave is a mechanical wave that causes the medium to vibrate
parallel to the direction of the wave. Its wave’s forces travel through
multiple rarefactions and compressions where compression is the closest
distance in the longitudinal wave and rarefaction is the farthest distance
apart in the said wave.
The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
or C. Mass if you're on plato
Sure. Body can move with uniform speed, and having zero velocity, when velocity becomes zero due to change in direction over time t.
For Example. - An Object is moving with uniform speed in a circular path, then after one complete revolution, it's velocity is zero, but speed still remains uniform
Hope this helps!
Heat
required in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC(T2-T1)
Heat = 1 kg (4.18 kJ / kg C)( 1 C)
<span>Heat = 4.18 kJ energy needed</span></span>
