Answer:

D 5 V

Explanation:

Without seeing the whole circuit it is impossible to say for certain.

However the simplest circuit would produce a value of

FV = IR = 0.25(20) = 5 v

A 2kg Book is sitting on a table.a 10n Force is pulling to the right.a 3n Force is pulling to the left what is the net force act
salantis [7]


The net force = sum of all forces acting on the body



If we take left side as -ve and right side as +ve,
then,

The net force here would be equal to,
10N + (- 3N)
= 7N.


Therefore, a net force of +7N ( + indicates it's moving towards right) is acting on the book of mass 2kg.

A vehicle of known mass accelerates along a straight path. According to Newton's second law of motion, what caused this accelera
Naily [24]

The answer would be:

C. An unbalanced force has acted on the vehicle.

The presence of an unbalanced force will accelerate an object, the second law of motion dictates this (Although not explicitly). Lets knock out the rest of the choices.

If a balance force acted on the vehicle, then the vehicle would be at rest. The mass of the vehicle did not change (Unless it falls apart, which I doubt). The direction of the vehicle does not change and it will only do so if another force and a stronger one at that will counteract the current net force acting on the vehicle.

Hope you got your answer here, although you did not ask for an explanation, maybe this will help you figure some of the other questions you have on your own.

melomori [17]
Power = (voltage) x (current)

100w = 220v x current

Current = 100w / 220v = <u>0.455 Ampere</u> (rounded)
