Answer:
the displacement would be 32 m
Explanation:
there is no formula for displacement, but you can use the velocity formula as you have the velocity and time so it looks like:

with x being the displacement

Explanation:
We have given wavelength of the photon 
Plank's constant 
We know that energy of the photon is given by

We know that energy of photon is also given by



Answer:
Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet (see the picture below). The compass needle aligns with the Earth's magnetic field direction and points north-south.
