Answers that apply include
- Energy is transferred through vibrating particles
- An ocean wave moving through water is an example of a mechanical wave
- A longitudinal wave is a type of mechanical wave.
- A transverse wave is a type of mechanical wave
Mechanical waves can't pass through vacuum like electromagnetic waves because t depends on the transfer of energy between particles of matter (matter that has inertia and elasticity). This energy propagates in the same direction as the wave. Another example of mechanical energy is sound. In addition to longitudinal and transverse waves, another type of mechanical wave is surface waves.
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
For this man
on his bike: Force = (20 kg) x (5 m/s²)
= 100 newtons .
This is NOT the "force produced".
This is the force NEEDED in order to accelerate THAT man
and his bike at THAT rate. If you don't have something that
can apply THAT force, then you can't create this situation,
and he'll just have to carry on, in the same direction and at
the same speed, without turning, slowing down, or speeding up.
I believe it was Copernicus' heliocentric model.
heliocentric - the sun is at the center and the planets revolve around it.
hope this helps :)
Answer:
a differenceis that the string needs force to be used. without something pulling on it then it wont make the noise. meanwhile the pipe only needs air to be blow Wich can be caused naturally or intentionally
