Answer:

when the coil spins in the magnetic field created by the magnets, the magnetic flux begins to change trough the coils, resulting in an electric field that generates the charge carriers through the wire.

As the wavelength increases, the frequency? A. decreases and energy decreases B. increases and energy increases C. decreases and

const2013 [10]

For the same wave, the product product of

(wavelength) times (frequency)

is always the same number. (It happens to be the speed of the wave.)

So if one of them changes, the other one has to change in the opposite
direction, in order to keep their product constant.

For electromagnetic waves, higher frequency means higher energy.
I'm not sure about mechanical waves just now.

The weight of a metal bracelet is measured to be 0.10400 N in air and 0.08400 N when immersed in water. Find its density.

Anna007 [38]

Answer:

The density of the metal is 5200 kg/m³.

Explanation:

Given that,

Weight in air= 0.10400 N

Weight in water = 0.08400 N

We need to calculate the density of metal

Let $\rho_{m}$ be the density of metal and $\rho_{w}$ be the density of water is 1000kg/m³.
