S= 1/2 x 182 x t = 1688.3
t = 1688.3 / 91
time = 18.55 seconds
They are similar because they are all colors in the spectrum and they are different because you cant seperate primary colors but you can seperate secondary
Answer:
The strength of the source charge's electric field could be measured by any other charge placed somewhere in its surroundings. The charge that is used to measure the electric field strength is referred to as a test charge since it is used to test the field strength. The test charge has a quantity of charge denoted by the symbol q.

Answer:
P + C = W if in equilibrium?
P + C - W = 0; P + C = W
Explanation:
Action and reaction are equal and opposite according to newton's third law of motion. a force is that which tends to change a body's state of rest or uniform motion in a straight line, recall
P is the upward force the person exerts on the crate,
C is the vertical contact force exerted on the crate by the floor,
W is the weight of the crate
let the sum of upward forces be on the left hand side of the equation and the sum of downward forces on the right hand side.
P+C=W
P+C-W=0 if they are in equilibrium
the forces are related by the above.
