JUU C. An eagle of mass 4.3 kg moving with speed 7.8 m/s is on a collision
course with a second eagle of mass 5.6 kg moving at 10.2 m/s in a
direction perpendicular to the direction of the first eagle. After they
collide, they hold onto one another.
i.
Find their speed after collision
[6]
ii.
Find their direction after the collision
[3]​

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

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

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
