A pendulum makes 50 complete swings in 2 min 40 second . what is time period for 1 complete swing?

3.2 seconds

Explanation:

50 swings = 2 mins 40 secs

= 50 swings = 2 x 60 + 40 secs

= 50 swings = 160 secs

= 1 swing = 160 / 50 secs

= 1 swing -= 3.2 secs

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

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
