The pendulum equation is t = 2pi * sqrt(l/g).
a) what variables should you plot against each other in order to prove that the period of the pendulum does not depend on its mass? what will the shape of this graph be?
b) what variables should you plot against each other to prove that the period depends on the gravitational field strength as shown by the equation?

0.55x745.7j and a calculator

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

amplitude
