How is power defined? Question 4 options: the quantity of work accomplished the direction of the work the total distance an obje
GarryVolchara [31]

Power can be defined as the rate at which work is accomplished.

Option D is the correct answer.

<h3></h3><h3>Power </h3>

The work done by an object in a given time interval is called the power of that object.

Suppose an external force F is applied to any object for the time interval T seconds. Due to this external force, the object will perform some amount of work for the time T seconds. This work W done by the object for the time interval T seconds is called the power of that object.

Power can be defined in mathematical term which is given below.

P = \dfrac {W}{T} \;\rm Watts

Thus the power can also be defined as the work done by the object per unit time interval.

Hence we can conclude that option D is the correct answer.

To know more about power, follow the link given below.

A man has a mass of 66 kg on the earth. What is his weight.
LUCKY_DIMON [66]
Since force = mass X acceleration, then the force he excerts on the earth (aka his weight) equals his mass times the force of gravity.

Therefore
W = (66 kg) X (9.8 m/ss)
W = 646.8 kgm/ss

kg m/ss are also known as Newtons, so your answer is...

646.8 N

Much power does a 10 Ohm bulb have in a series circuit with a battery of 12V and nothing else in the the circuit?
Sedaia [141]

Answer:

it will be d) 14.4W

Explanation:

potential difference (v) = 12 volts

resistance (r) = 10 ohms

now, we know

=》

power =  \frac{v {}^{2} }{r}

=》

power \:  =  \frac{12 {}^{2} }{10}

=》

power =  \frac{144}{10}

=》

power = 14.4 \: watt
