A laser produces light at 5.32x10-7 m.
Blababa [14]

Answer:

D

Explanation:

speed = frequency x wavelength

speed of light in vacuum is 3.0 x 10^8

wavelength = 5.32 x10 ^-7

3.0 x 10 ^ 8 = 5.32 x 10^-7 x frequency

frequency = 5.63909 x 10^14

round it off = 5.64 x 10^14 Hz

thus the answer is D

hope this helps please mark it

vesna_86 [32]

Answer:

Option C is correct.

The component of acceleration perpendicular to an object’s velocity tells us How the object’s direction changes.

Explanation:

This acceleration is called radial/tangential acceleration. It is the reason why a body moving in circular motion with constant velocity can be said to also be accelerating because its direction is continuously changing. The acceleration is usually directed towards the centre of the circular motion of the body or trying to throw the body off its circular motion path.

The electric motor in a toy train requires a voltage of 4.9 v. find the ratio of turns on the primary coil to turns on the secon
enyata [817]

So to solve for this problem, this is computed by the following steps:

 

Vp / Vs ( = Np / Ns

Where:

Vp = Voltage Primary

Vs = Voltage Secondary

Np = Turn ratio Primary

Ns = Turn ratio Secondary.

So plugging in our values: <span>
110 / 4.9 = N</span>p / Ns<span>
N</span>p / Ns =22.44, so <span>the answer is 22 coils.</span>
