If the force applied to a cart
increases, then the acceleration of the cart increases
when the mass of the cart is held constant, because
force and accelerationſ are directly proportional to each
other according to newton's second law.

How do you tell if someone actually cares about you? and just say they do?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?
