It can be concluded that John lives at the Arctic Circle.
<h3>
</h3><h3>Why sun don't sets at arctic circle?</h3>
The North Pole is inclined toward our star throughout the summer because of the slanted axis of the earth's rotation with respect to the sun. Because of this, the sun never sets over the Arctic Circle for a few weeks.
Norway. Norway, which is located in the Arctic Circle, is known as the Land of the Midnight Sun because there the sun never sets from May until late July. This implies that the sun doesn't set for around 76 days.

The potential energy of a 25 kg bicycle resting at the top of a hill 3 m high will be 735.75 J.
<h3>What is potential energy?</h3>
The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.
The potential energy is mainly depending upon the height of the object. when the cyclist is at the highest position, the height is maximum. Therefore, the potential energy is also maximum.
The potential energy is found as;
PE=mgh
PE=25 kg× 9.81 m/s² ×3 m
PE= 735.75 J.
Hence, the potential energy of a 25 kg bicycle resting at the top of a hill 3 m high will be 735.75 J.

-- Gravity adds 9.8 m/s to the downward speed of any object, every second ... as long as there are no other forces messing with it.
-- In 0.6 sec, gravity added (0.6x9.8)= 5.88 m/s to the downward speed of this ball.
-- This ball didn't start from zero. You threw it down with an initial speed of 1 m/s. So after 0.6 sec, with the help of gravity, its speed is
(1) + (5.88) = 6.88 m/s .
Pick choice-C .
Notice that we don't care how high it was off the ground when you threw it, just as long as it was high enough to keep falling for 0.6 sec without hitting the ground.
