D=vt use this equation to get the depth of the skull
Answer:
v=wavelength ×f
wavelength=v/f=455/655=0.694m
Answer:

Explanation:
Density can be found by dividing the mass by the volume.

The mass of the quartz is 30 grams and the volume is 6 cubic centimeters.

Substitute the values into the formula.

Divide.

The density of this piece of quartz is 5 grams per cubic centimeter.
Explanation:
<u>Mass of car</u> = 137.5 kg
<u>Acceleration</u> = v - u / t = 26 - 0 / 6 = 4.33 m/sec^2
Force = m * a = 137.5 * 4.33 = 595.3 N
A piece of blue paper appears blue because the paper absorbs all colors of light except blue. <em> (b)</em>
So any light that bounces off of the paper and enters your eye must be blue light !
