Two force F1 and F2 act on a particle. F1 has magnitude 6N and in direction 045°, and F2 has the magnitude 7N and in direction 154°. Find the magnitude and direction of their resultant.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

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

technology is the application of the knowledge gained by science.

the answer is 100. i just did this lesson and got a 100% on it. : )
