There is a nut on the bottom of the pendulum to adjust the speed. Turning it clockwise speeds it up, counter clockwise slows it down
A longer pendulum will result in a longer period. The clock would go slower.
The longer a pendulum is, the more time it takes a pendulum takes to complete a period of time. If a clock is regulated by a pendulum and it runs fast, you can make it run slower by making the pendulum longer. Likewise, if the clock runs slow, you can make your clock run faster by making the pendulum shorter. (What a pendulum actually does is measure the ratio between time and gravity at a particular location, but that is beyond the scope of this answer.)
TRUE
730 minutes slow (12.167 hours slow, so basically half a day slow) In other words it would be correct if it didn't say PM or AM.
The clocks would read 16 minutes earlier than the actual factual time. Sadly, you haven't told us what time it really is. Incidentally, a clock can be 16 minutes 'behind', but it can't be 16 minutes 'slow'. If a clock is 'slow', then the amount of time it loses depends on how long it's been running since it was set, and would be expressed in units of "minutes per hour", or some other such dimensionless ratio.
If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.
To slow down a swinging clock pendulum, one must make it longer. In mechanical clocks, the majority of the mass of the pendulum is contained in the "bob" (a disk or weight) usually at the bottom of the pendulum. If you lower the pendulum bob, the pendulum is lengthened and the pendulum runs slower. This is usually done by turning a nut on a threaded portion of the pendulum just below the bob. Make sure the bob drops as you lower the nut or nothing will change. To raise the rate of the pendulum (make it run faster), you just turn the nut the opposite way.
A slow pendulum clock is sp[eeded up by decreasing the effective length of the pendulum. The weight on the pendulum is usually mounted such that it can be slid up and down the swinging arm. Sliding the weight up slightly decreases the effective length of the pendulum, and slightly increases the rate at which the clock runs. It should be done only in tiny adjustments, because the size of the change might not even be noticeable until a day or two later.
pendulum's slow down during summers because the pendulum expands and it moves faster during winters because the pendulum contracts
You would do it by adjusting the pendulum. By moving it slightly down, you should slow it down. It may take a while to find the correct length.
A longer pendulum will result in a longer period. The clock would go slower.
The pendulum will lose energy, due to friction.

The pendulum of a clock is usually constructed with some sort of clamp or sliding catchthat permits sliding the weight up and down the stick, raising or lowering its center of massand thus changing its effective length.-- If the clock is running too fast, and has to be turned back a few minutes every now and then,make the pendulum slightly longer, by sliding the weight down a bit on the stick. This makesthe pendulum swing slightly slower.-- If the clock is running too slow, and has to be turned a few minutes ahead to catch up everynow and then, make the pendulum slightly shorter, by sliding the weight up a bit on the stick.This makes the pendulum swing slightly faster.
Air resistance.
During the summer the pendulum which is generally made of metal, expands due to the rise in temperature. this causes the pendulum to move slower and hence the clock becomes slower.
