What is the inverse of tan?
What is the inverse of tan? Inverse tan is the inverse function of the trigonometric function ‘tangent’. It is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle. Based on this function, the value of tan 1 […]
What is the physical property of filtration?
What is the physical property of filtration? Physical separation methods, such as filtration and distillation, are based on the difference in particle size and on the boiling point of the substances in the mixture, respectively. These are properties that can be observed and measured without changing the material itself. What kind of mixture can be […]

What are the 3 ways machines make work easier?
What are the 3 ways machines make work easier? Background Information. There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. Why is no machine 100 efficient? A machine cannot […]

What keeps the sun from exploding?
What keeps the sun from exploding? The inward pressure that keeps a star from exploding is the gravitational attraction of the gas mantle surrounding the core (which is most of the volume of the Sun, and is very hot but does not burn itself). Why does the sun not explode like a hydrogen bomb? The […]
