here in the given situation if monkey starts free fall at the same instant when veterinarian shoots towards it then we know that vertical component of motion of monkey and the dart will be same as under gravity
so here the dart will always hit the monkey because they both moves under same acceleration
so here for the angle we can use
now we have
H = 3 m
L = 87.5 m
now we will have
so angle will be 1.96 degree above the ground
The same bird on the tree has more gravitational potential energy. This is because it is at a higher distance from the ground as it is on the tree, than when it is on the ground.
Considering also the formula for Gravitational Potential Energy GPE = mgh
For the bird on the ground, h =0, therefore GPE = m*9.8*0 = 0
For that on the tree = mgh = m*9.8*h
Of course the one on the tree has a value greater than zero.
C. A narrow wind complains all day.
Personification is a figure of speech wherein animals, objects, and ideas are given human traits or characteristics.
The narrow wind, which is an unseen object, was given a human trait which is complains.
Answer:
The purpose of step 1 is to induce magnetism into the needle, so that it retains magnetism and behaves as a magnet after the process.
Explanation:
The method of production the needle magnet in the procedure is the single stroke. This process involves a continuous stroking of a magnetic object (e.g needle) repeatedly for a period or number of times with a permanent magnet. Thus, when the permanent magnet is removed, the object retains magnetism, and behaves like a magnet.
The importance of the stroking process is the turn a magnetic object to a magnet by inducing magnetism into it.
