A0.600 m long pendulum is used to determine the acceleration due to gravity on a distant planet. if 20 complete oscillation are completed and 35.5 seconds, the acceleration is a) 7.52 m/s squared b) 9.81 m/s squared c) 30.5 m/s squared d) 42.0 m/s squared

Answer :

Explanation :

It is given that,

length of pendulum, l = 0.6 m

Number of oscillation, n = 20

time, t = 35.5 seconds

so, Time period,

we know that the time period of pendulum is given by

or

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
