Please help me !
If a 3.0j of work is done in raising 175 g apple , how far is it lifted?

The formula for calculating work done against gravity is W = mgh, where W is the work done, m is the mass of the object, g is the acceleration due to gravity, and h is the height the object is lifted.
The direction of work done against gravity is determined by the direction in which the force is applied. If the force is applied in the same direction as the displacement, the work done is positive. If the force is applied in the opposite direction of the displacement, the work done is negative.
Yes, work can still be done against gravity when an object is not moving. This is because work is defined as the product of force and displacement, not the actual movement of an object. If a force is applied to an object against gravity, but the object does not move, work is still being done.
The unit of measurement for work done against gravity is joules (J). This is the same unit used to measure energy and is equivalent to 1 newton-meter.
Yes, the work done against gravity can be zero if the object is not moved or if the force applied is perpendicular to the displacement. In these cases, there is no component of force acting in the direction of the displacement, so no work is being done against gravity.
