Answer: 1
an object positioned at some height in a gravitational field
Explanation:
Gravitational potential energy of an object is the energy stored due to position of the object or position at certain height relative to zero position.
Gravitational potential energy can also be expressed as object position at some height above or below zero position in a gravitational field
I think 1 and 2 make sense. But 1 make more sense than 2
If an object changes direction while travelling will an object's displacement and distance travelled be different.
Some people believe that distance and displacement are simply different names for the same quantity. However, distance and displacement are not the same thing. If an object changes direction while travelling, the total distance travelled is greater than the displacement between those two points.
The magnitude of the displacement is always less than or equal to the distance because it is measured along the shortest path between two points.
When the direction of displacement does not change, the magnitude of the displacement and distance are the same. When a body travels in a straight line, for example, its displacement and distance are the same.

Answer:
hmm
Explanation:
By increasing the number of turns in the coil, strength of magnetic field, speed of rotation of the coil in the magnetic field and by decreasing the distance between the coil and the magnet the magnitude of the induced e.m.f. can be increased in generator/dynamo.
Answer:
accuracy refers to the deviation of a measurement from a standard or true value of the quantity being measured
