The piston diameters in fig. p1-58e are d1 = 10 cm and d2 = 4 cm. when the pressure in chamber 2 is 2000 kpa and the pressure in chamber 3 is 700 kpa, what is the pressure in chamber 1, in kpa?

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) .

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

What are two different ways you could find the value of a? explain these methods.
