Calculate the power in watts used if you exert 50 joules of work in 5 seconds?

Watts is joules per second, so 50 joules in 5 seconds is 10 watts.

It takes 100 N to move a box 10 meters in 5 seconds How much power is required?

Work in Joules = force x displacement= 100N x 10meters= 1000 JoulesPower in Watts = work/seconds= 1000 Joules / 5 seconds= 200 Watts200 W

Which of these has the most power?

an electric sander that does 5000 joules of work in 5 seconds

How many watts are 4680000000joules?

Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.

What power was used if it took 2 seconds to move a 10 newton box 5 meters?

The weight of the box is irrelevant. The only thing that matters is how hard you push on it.Since it's the only number given, let's assume that the 10 Newtons is the force you applied to the box,and that by applying that force to the box, you were able to move it 5 meters in 2 seconds.The work you did is [ force x distance ] = 10 x 5 = 50 joules.The power is [ energy / time ] = 50/2 = 25 joules per second = 25 watts.

If 50 joules are used in ten second would the power be 500 watts?

50J /10 s =5 W

If you did 100 j of work in 5 s what was your power output?

If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.

If 10 joules in 20 seconds how many newtons?

You can't calculate the force from the rate at which work is done.10 joules in 20 seconds could be:-- 1 newton pushing along at 50 centimeters per second, or-- 0.1 newton pushing 5 meters per second, oran infinite number of other possibilities.From the data given in the question, all we know is that the 'power' is 1/2 watt.

How many minutes and seconds are 350 seconds?

There are 5 minutes and 50 seconds

Which is faster 50 meters in 10 seconds or 30 meters in 5 seconds?

50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..

What is the power in watts when 7500 J of energy are used in 5 h?

Although most of the time power is measured in Watts, it can also be expressed as Js-1. So in your question, you are given the amount of joules and the time in hours. First, convert 5 hours to seconds. There are 60 mins in an hour and 60 seconds in a minute. So that's going to be 5x60x60 = 18000 seconds Now all you do in divide the number of joules by the number of seconds to work out the power. So that's 7500/18000 = 0.41666666666... approximately, 0.42Js-1(2dp) and thats the same as 0.42W (2dp)

How many joules are required to push a box 10 meters with a force of 5 N?

A joule is a neuton metre. i.e. 10*5 = 50 joules are required.

If distance is 50 meters and time is 5 seconds what is the speed?

If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.

How much work is done by 10 newton to push 5 meters?

10 x 5 = 50 newton-meters = 50 joules

What is 350 seconds in minutes and seconds?

It is: 350/60 = 5 minutes and 50 seconds

How many minutes are in 350 seconds?

There are 5 minutes and 50 seconds.

How much power does a person weighing 500 N need to climb a 3 meter ladder in 5 seconds?

Work = 500 x 3 = 1,500 joulesPower = (work/time) = 1,500/5 = 300 watts = about 0.4 horsepower (rounded)

How many seconds are in 5 minutes 50 seconds?

60 sec = 1 min. 60 x 5 = 300sec + 50 sec = 350sec

A toaster on 220 V line draws a current of 5 A How much heat does it generate in 10 minutes?

First calculate the power: P = I2R. Power will be in watts. Then multiply power x time to get the total amount of energy transferred. If the time is in seconds and the power in watts, the energy will be in joules. (In this case you need to convert the time to seconds first.)

Exert 100 J in 50 s and your power output is?

power is how many Joules are used every second. So if we use 100J in 50s then we must be using 2J per second (you deivde everying by 50 to get that). Watt is the unit of power! (that's not a question) so our answer is 5 watts.

What if your exert 800 N of force in moving a piano 10 meters in 5 seconds how much power do you expend?

Work = (800 newtons) x (10 meters) = 8,000 newton-meters = 8,000 joulesPower = (work) / (time) = (8,000) / (5) = 1,600 watts

What fraction of a minute is 50 seconds?

It is: 50/60 = 5/6 simplified

What is 5 minutes and 40 seconds plus 8 minutes and 50 seconds?

14 minutes and 30 seconds.

What is the kinetic energy of an object that has a mass of 4 kg and a velocity of 5 ms?

Kinetic energy = (1/2)mv2, where m is mass and v is velocity.In this case, mass is 4 kg and velocity is 5 m/s, so K = (1/2)(4)(5)2 = 50 Joules.(The units of energy are Joules, as long as everything is measured in kilograms, meters, and seconds.)

How many watts of motor are required for 30 kg material?

If it's to lift 30 kg, it depends how far it is to be lifted and how quickly the lift takes to complete. To lift 30 kg through 10 metres requires 30 x 9.8 x 10 joules of energy, that is 3000 Joules. To do that in 10 seconds needs 300 watts, which would be about half a horse power motor. To do it in 5 seconds the power would be 600 watts - a 1 horse power motor.
