The 200-mm test tube also contained some water (besides the metal) that was subsequently added to the calorimeter (in part a. considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique error?

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.
