Sarah weighs 500 newtons. she climbs a set of stairs 6 meters high. how much work does she do? 83 j work equals force times distance. 0.012 j work equals force times distance. * 3,000 j work equals force times distance. 6,500 j work equals force times distance.

Work equals force times distance. 3,000 J

Explanation:

Work Done By A Force

When some force is applied and a displacement is achieved, the work done by the force is given by

Note that the work is a scalar magnitude as the result of the dot-product of two vectors. If the force and the displacement are parallel, then the vectors can be replaced as its magnitudes F,x and the work is

The dot product becomes a simple arithmetic product, i.e force times distance.

Sara weighs 500 Nw and she climbs up a 6 meter set of stairs. She needs to lift her weight up, so the force is the weight and the distance is the height of the stairs, thus

Work equals force times distance. 3,000 J

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
