Find the power load P in kilowatts of an electrical circuit that takes a current I of 17 amperes at a voltage V of 320 volts if
MA_775_DIABLO [31]

Answer: P = 5.44 KW

Explanation:

The formula for calculating power is expressed as

P = VI

where

v is the voltage

I is the current

From the information given,

v = 320

I = 17

Thus,

P = 320 x 17 = 5440 W

We would convert it to KW by dividing by 1000. It becomes

P = 5440/1000

P = 5.44 KW

True or False: Our food has potential energy?
DanielleElmas [232]

Hello User,

Answer is yes.

A sled with a mass of 25.0 kg rests on a horizontal sheet of essentially frictionless ice. It is attached by a 5.00-m rope to a
Tpy6a [65]

Answer:

The value is  F  =  34.3 \  N

Explanation:

From the question we are told that

    The mass of the shed is  m  =  25 \  kg

    The length of the rope is  l = 5.0 \  m

    The angular speed of the shed is w = 5 rev/minute = \frac{2* \pi * 5}{60 }= 0.524 \  rad/sec

Generally the force exerted on the shed is mathematically represented as

     F  =  m  *  w^2 *  l

=>  F  =  25  *  0.524^2 *  5

=>  F  =  34.3 \  N
