Jim is playing with a 1–meter–long pendulum that is hooked 2 meters above the ground. He lifts the pendulum's bob to a height of 2 meters above the ground and then releases it. Potential energy is assigned zero value at the ground level. Which statement is true about this problem?

d. air pressure decreases as altitude increases.

the closer the planet is to the sun, the larger the gravity

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
