Write down two examples of where ramps are used

Inclined planes are widely used to move heavy loads over vertical obstacles.

Explanation:

examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
