What conversion factor is used to convert 20 cm to m

1 answer:

7 0

The conversion factor you use is 100 cm = 1 m.
You can divide 20 by 100 to get the answer.
20 cm/100 cm =.2 m
Hope this helped!

A laser emits light of frequency 4.74 x 1014 hz. what is the wavelength of the light in nm?

Ulleksa [173]

Use this formula:Wavelength=c/v, where c is the speed of light, and v the frequency. 6.33 X 10^-7=3 X 10^8/v v=3 X 10^8/6.33 X 10^-7 v=4.74 X 10^14 Hertz,

The table below shows the acceleration of gravity on different bodies in the solar system.

levacccp [35]

Do you remember the formula for potential energy ?

PE = (mass) (gravity) (height)

If the mass and the height are always the same, then the least PE comes from the least gravity. Surely you can find THAT in the table.

A remote-controlled car's wheel accelerates at 22.6 rad/s2 . If the wheel begins with an angular speed of 10.2 rad/s, what is th

Lapatulllka [165]

Answer:

70.9pi rad/s

Explanation:

angle turned through = 16

angular acceleration = 22.6 rad/s2

angular speed = 10.2 rad/s

time = ?

angular acceleration = angular speed/time

time = 10.2/22.6

time = 0.45 seconds

angular speed = angle turned through/time

angular speed = (16 × 2pi)/0.45

= 70.9pi rad/s

Energy cannot be _________ or ___________ just ______________ in form.

djverab [1.8K]

Answer: Energy cannot be created or destroyed just changes in form.

Explanation:

This is the principle of the first Law of Thermodynamics, which relates the work and the transferred energy exchanged in a system through the internal energy, which is neither created nor destroyed, it is only transformed.

In other words: The total energy of a system is always conserved.
