Grandfather clocks are designed so they can be adjusted by moving the weight at the bottom of the pendulum up or down. suppose you have a grandfather clock at home that runs fast. which of the following adjustments of the weight would make it more accurate?

a. raise the weight.
b. decrease the amplitude of swing by a small amount.
c. add more mass to the weight.
d. lower the weight.
e. remove some mass from the weight.

Partamos definiendo la expresión del período, el cual esta dada por

Where,

l = length

g = Gravity

Of these options gravity on earth remains constant, so the only variable to move is length.

The length is directly proportional to the period, the longer it is, the higher the value of the period of the object will be. If the object goes too fast, it is necessary to increase the length.

From the options given above when adding length it is also inferred that weight is added, so the correct option would be Raise the Weight

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
