The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

Work done is a measure of consuming energy or it is the capacity of doing a certain work and that also means the same . Work is something which we do which consumes or produces energy or there will be a net increase or decrease of energy. Net work done is the sum of work done by all forces.

To determine the total variable cost the company will spend to produce 100 units of product, the following formula is used: Total output quantity x variable cost of each output unit = total variable cost. For this example, this formula is as follows: 100 x 37 = 3,700.

1 Answer. Work is done only when a certain force is applied on a object and the object moves a certain distance on the direction of the applied force. hence work done is zero when the direction is perpendicular.

Let us calculate the work done in lifting an object of mass m through a height h, such as in Figure 1. If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh.

Work = Mass * Gravity * Height The equation above shows how to calculate the work done. As you can see, your work will be the same – no matter which path you take - because your mass doesn't change during the trip. Gravity doesn't change. The final height is the same.

To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply a typical 40 hour work week by 52 weeks. That makes 2,080 hours in a typical work year.

['The job requires= 12 x 18= 216- man-days.', 'In 6- days(6 x12)= 72-man - days of work was completed.', 'The remaining (216–72)= 144 man-days will be completed by (12+4)= 16- men in = 144/16= 9- days.']

To get the Percent Completed, we divide the Total Number of Working Days Completed by the Total Number of Working Days. To get the Expected Progress we look at Todays Date Line within the Gantt, and for each task we calculate what percentage of the Task should be complete by Todays Date Line.

First, multiply your weight by the number of minutes you exercised. For example, if you weigh 140 lbs. and lifted weights for 35 minutes, the formula would be 140 x 35 = 4900. Then multiply this number by the intensity value to get the number of calories burned.

Calculate the kilowatt-hours (kWh) required to heat the water using the following formula: Pt = (4.2 × L × T ) ÷ 3600. Pt is the power used to heat the water, in kWh. L is the number of liters of water that is being heated and T is the difference in temperature from what you started with, listed in degrees Celsius.

Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.

A completes a work in 16 days. So percentage of work done by A per day is 100/16 which is 6.25%. After 12 days the percentage of work completed will be (14.58*6) which is 87.48. On 13th day A will start to work, hence after 13 days work completed will be 87.48+6.25 = 93.73.

Insert milliamp hour (mAh) and voltage (V) and click on Calculate to obtain Watt hours (Wh). Formula is (mAh)*(V)/1000 = (Wh). For example, if you have a 300mAh battery rated at 5V, the power is 300mAh * 5V / 1000 = 1.5Wh.
