Folded layers of rock can form a wavelike pattern of troughs and crests. the layers near the crest (i. e. the upward fold) form a) a syncline. b) a tension zone. c) an anticline. d) a thrust fault.

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) .

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage
