Transverse waves occur when a disturbance causes oscillations perpendicular
dropped from the bridge, how much time passes before the
object makes a splash?
Answer: 7.436 s
Explanation:
This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:
Where:
is the final height of the object (when it makes splash)
is the initial height of the object
is the initial velocity of the object (it was dropped)
is the acceleration due gravity (directed downwards)
is the time since the objecct is dropped until it makes splash

Finally:
Answer:
nuclear energy
Explanation:
insulator
semiconductor
superconductor
Answer:
An insulator
Explanation:
Insulators have a very high resistance because the electrons of the insulator are bounded strongly with the nucleus. Hence it requires more voltage to move an electron from the valence band to the conduction band.
The ball's force back on the foot= 500N
What is the net force on the ball?
What is the net force on the foot?
Answer: centimeters per second (cm/s)
Explanation:
The relation between the frequency and the wavelenght is:
Velocity = wavelenght*frequency.
So in a relation of wavelenght vs frequency, we will have the relationship:
Where wavelenght is Y and frequency is X
wavelenght = velocity/frequency.
So the constant is the velocity, and we know that the units of the wavelenght is cm, the unit of frequency is Hz (or 1/s), so the units of the velocity is cm/s
Answer:
cm/s
Explanation:
λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.
λ = c/v which is in cm/s/Hz
But we would use just cm! Because that's how we measure the wavelength in this example.
However, the constant is c, the speed of light, which we measure as a speed, so cm/s will do.
