Density is a physical
property which describes the mass of a substance per unit of volume of the substance.
It is expressed as Density = m / V and it has units like g/cm^3. We use the
density given to solve the problem.
<span> Volume of the tank = 8 fishes / 0.2 fish / ft</span><span>³</span>
<span>Volume of the tank = 40 ft</span><span>³</span>
Answer: Longitudinal wave
Explanation:
Longitudinal wave are the oscillations that are parallel to the direction of energy transfer that means the vibrations are in line with the direction where the energy is travelling.
A key feature of sound wave is that they cause sound particles to vibrate. The region where the particles are close together are called compressions and regions where particles are further apart they are called rarefactions.
The other options explanation:
-Transverse waves are where the oscillations are perpendicular to the energy of transfer.
-A standing wave is where the waves are travelling back and forth where there are some fixed points in the system whilst other vibrate with highest amplitude
-Surface waves have both the characteristics of longitudinal and transverse waves
Answer:
Protium
Explanation: Protium is an isotope of hydrogen that is composed of one proton and one electron. It is the most abundant form of hydrogen.
A gas as 30.0 Ml because pile of 1.4 add 1 that equals. To 1.5 and remove 10 so thebpresssure is 1399.93
Answer:
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Explanation:
When an athlete tries to stop his career, it takes several meters to stop completely, due to the inertia produced.
When trying to push a car, at first it is very difficult, because, due to inertia, the car tends to remain still. But once it is put into motion, the effort is much less to be done, since then inertia causes it to keep moving.
