The properties that change how we perceive light waves are the following:
The amplitude of the light wave changes the brightness of light relative to other light waves of the same wavelenghth.
The frequency of the light wave changes the color and the type of the light wave.
Answer:
1.5F
Explanation:
Using
E= F/q
Where F= force
E= electric field
q=charge
F= Eq
So if qis tripled and E is halved we have
F= (E/2)3q
F= 1.5Eq=>> 1.5F
Explanation:
this is a physical property
Answer:
206.8965517 n
Explanation:
First, we need to see that 60:29 is 2.078965517:1. Then we need to multiply the energy put 29 cm from the fulcrum by 2.078965517, giving us the end result of our answer.
Answer:

Explanation:
In series combination, the equivalent resistance is given by :

Let the identical resistors be R. We have, 
So,

So, the resistance of each resistor is
.
