Hello!
Use <u>ohm law:</u>
I = V / R
Replacing:
I = 100 V / 20 O
I = 5 A
The current is <u>5 amperes.</u>
Answer:
An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.
Explanation:
Answer:
Electromagnetic wave are waves formed as a result of the oscillatory activities involving the electric and the magnetic field.
However in an Electromagnetic wave, the electric field and magnetic field carry equal amounts of energy and the magnitude of the electric field is directly proportional to the magnitude of the magnetic field. This direct proportionality gives rise to the speed of light being the constant between the two fields.
When the electric field is doubled then an equal action is to be set for the magnetic field so it doesn’t deviate from its main functions and characteristics.
Answer:
Explanation:
When at rest, initial velocity = 0
In 2 seconds, final velocity = 2 m/s
Acceleration = (final velocity - initial velocity) / time
= (2 - 0) / 2
= 1 m/s^2
East is our x axis
north is out y axis N

S
so he moves 3 m to the right and then 4 upwards
imagine what that looks like.......... a right angle triangle
therefore we can use Pythagorean theorem
let the unknown side be x, which is the hypotenuse in this case
x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
take the square root
x = 5
5 is your magnitude and the direction is NE( North East) or positive direction
