The rate at which a car uses perol (at a certain speed) is 0.024 golm? Cáczasu that the car would travel if the petrol tank contains 30 litres 1 gal= 231 inch' and mil is mile

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

technology is the application of the knowledge gained by science.
