Following are the correct options:

Melting

The molecules gain energy and break the bonds between them which causes a transition from solid to liquid

sublimation

A substance gain energy and changes from solid to gas.

vaporization

The atoms gain energy and the matter changes its state from liquid to gas.

Answer:

Melting

Sublimation

Vaporization

Explanation:

There are mainly 3 states of matter: solid, liquid and gas. There is change in one state to another when there is heat transfer. when the atoms gain energy, there state changes from solid to liquid to gas. When the atoms lose energy, the state changes from gas to liquid to solid.

In Melting process, atoms gain energy and their state of the matter changes from solid to liquid.

In sublimation process, atoms gain energy and their state of the matter changes from solid directly to gas.

In vaporization process, atoms gain energy and their state of the matter changes from liquid to gas.

In rest of the processes, atoms lose energy.

Zepler [3.9K]

Body waves

Explanation:

A shear wave(S-wave) is a type of seismic body waves that shakes the ground back and forth perpendicular to the direction the wave is moving.

  • Seismic waves are elastic waves usually generated when there is a disturbance within the earth.
  • There are two types of seismic waves:

                 Surface waves

                  Body waves

  • Body waves travel within the earth and they cause disturbances there. P and S waves are the two types of body waves that we have.
  • Surface waves travels on the earth surface. They are the love and rayleigh waves. They are the ones that cause destruction on the earth surface during an earthquake.

Suppose you are designing an amplifier and loudspeaker system to use at a rock concert. You want to make it as loud as possible.
OverLord2011 [107]

Answer is given below

Explanation:

  • Audio power amplifiers are found in all types of sound systems, including sound reinforcement, public address and home audio systems, as well as musical instrument amplifiers such as guitar amplifiers.
  • This is the last electronic step in the general audio playback series before sending the signal to the loudspeaker.  So when we want maximum volume or loud sound, we have to get it with maximum output and high input and low output impedance

Of waterfalls with a height of more than 50 m , Niagara Falls in Canada has the highest flow rate of any waterfall in the world.
Vinil7 [7]

Answer:

Power output: W=1426.9MW

Explanation:

The power output of the falls is given mainly by its change in potential energy:

Q=-P_{tot}=-(P_{2}-P_{1})

The potential energy for any point can be calculated as:

P=m*g*h

If we consider the base of the falls to be the reference height, at point 2 h=0, so P2=0, and height at point 1 equals 52m:

Q=P_{1}=m*g*h

If we replace m with the mass rate M we obtain the rate of change in potential energy over time, so the power generated:

W=M*g*h=2.8*10^{3}m^{3}/s*1*10^{3}kg/m^{3}*9.8m/s^{2}*52m =1426.9MW
