Answer:
Vibrations of electric and magnetic fields.
Vibration of air particles
Vibration of the water particles.
Explanation:
We have here two groups of waves. Electromagnetic wave and mechanical waves.
- For the first one, electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
- For the second group, mechanical waves as a sound, for instance, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. Or In water waves, energy is transferred through the vibration of the water particles.

FORCE ACTING ON THE BODY , F = 200N
AREA ON WHICH THE FORCE IS ACTING , A = 0.05 CM²
= 0.05*(10⁻²)
= 0.05*10⁻² M²
TO CONVERT CM TO M * BY 10⁻²
PRESSURE = FORCE / AREA
PRESSURE = 200/0.05*10⁻⁴
= 200*10⁴/0.05
= 200*10⁴*10²/5
= 20*10⁵/5
= 4*10⁵ N/M².

Answer:
Which microphone captures a singer's low sounds the loudest?
Explanation:
Scientific questions are the basis of any scientific experiment. An observation is followed by a scientific question. In this question, scientists are investigating how well different microphones capture and record sounds by using tools that show how loud the high and low sounds are and a tool that shows how much noise is recorded along with the actual sounds.
Hence, a scientific question should be that which will cover the whole aspect of the investigation i.e. the question should contain a general scope of the problem. Hence, a scientific question that could be included in this investigation is:
Which microphone captures a singer's low sounds the loudest?
This is because this question contains every part being investigated i.e. How different microphones capture sounds and records them (whether low or high).
Answer:
lesser time
Explanation:
The latent heat of fusion is defined as the amount of heat required to convert 1 gram of water into 1 gram of ice at constant temperature called melting point.
In this situation only the state of matter is changed, the temperature of the substance remains constant.
A liquid has lower latent heat rather than water, it means it requires lesser amount of heat to fuse it , so it requires lesser amount of time to melt the ice made by this liquid.
So, it requires lesser time.
Answer:
Scientific models have two basic types. FALSE.
