The equivalent formula for p = iv is the startfraction p over v endfraction = i
In physics, power measures the rate of transfer of electrical energy through a circuit per unit of time. It is denoted by P and is measured using the SI unit of power (watts or 1 joule/second). Electrical energy is usually supplied by batteries and produced by generators.
There are three types of power, true, reactive, and apparent, which are related in trigonometric form. This is called the power triangle. A power triangle that relates apparent power to active and reactive power. Power is measured in watts. One watt equals one joule per second.

Answer:
The acceleration of the box is 2.
Explanation:
According to Newton's second law of motion, the acceleration of any object will be directly proportional to the net unbalanced force acting on the object and inversely proportional to the mass of the object.
Net force = Mass × Acceleration
So 
Since in this case, the box is experiencing a force from east of magnitude 27 N and resisting force of about 17 N from west. So the net force will be the difference of acting and reacting force.
Net force = 27-17 = 10 N.
Thus, 
So 2 
is the acceleration of the box. Thus the magnitude of acceleration of the box is 2.
Planck's constant is 4.39048042 × 10-67 m4 kg2 / s2.
Answer : The correct option is (D).
Explanation :
Given that,
A track begins at 0 meters and has a total distance of 100 meters. Juliet starts at the 10-meter mark while practicing for a race.
We have to find her position after she runs 45 meters.
From the attached figure,
Let A is the position of Juliet. O is the initial point such that OA = 10 m, AB = 45 m and OP = 100 m.
So, using simple mathematics, it is clear that the position of Juliet after running 45 meters will be 55 m. It is OB in the figure.
So, the correct option is (D) " 55 meters ".
Answer:
No. Tension Force Elastic Force
1. A force transmitted through a wire, rope or a string when it is pulled from opposite ends is known as a tension force. A force that allows an object to return its original shape after being stretched or compressed is known as an elastic force.
2. Example: Pulling a rope from two opposite ends
When a rope is pulled from two opposite ends, a tension is generated in rope.
Due to this tension, a force is transmitted through a rope which is known as a tension force. Example: Stretching a rubber band
When a rubber band is stretched, it gets stretched easily due to its elastic nature.
The more a rubber band is stretched, the more force it will exert to return back to its original shape.
This force is known as an elastic force.
