In a certain clock, a pendulum of length l1 has a period t1 = 0.95s. the length of the pendulum
is adjusted to a new value l2 such that t2 = 1.0 s. what is theratio l2/l1?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .
