The force applied to the physics cart is manipulated. This is the variable.

The cart accelerates due to the force applied to the cart. Acceleration is therefore the
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
.

What is the magnitude of the resultant vector round your answer to the nearest tenth

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Contains chemical energy. a. heat b. light c. natural gas
