Q. A light spring with a spring constant of 80.0 N/m rests vertically on a table. A 2.00 g balloon is filled with helium (0°C and 1 atm pressure) to a volume of 5.00 m3 and connected to the spring, causing the spring to stretch and expand. How much does the spring stretch when the balloon-and-spring system is in equilibrium? (The density of helium is 0.179 kg/m3)
Q. How much internal energy is generated when a 30.0-g lead bullet, traveling at 6.00 102 m/s, comes to a stop as it strikes a metal plate?
All distant galaxies are moving away from us. Describe why this does not imply that we are at the center of universe.
On another planet the simple pendulum consisting of a 0.154 kg mass suspended on a 1.20 m long string has a period of 3.860 seconds. What is acceleration on this planet.
What is the kinetic energy
A conveyor belt at a quarry lifts 2,000 kg of sand per minute up a vertical distance of 12 meters. The sand is at first at rest, then moves at a speed of 0.20 m/s along conveyor belt. What is the instantaneous power generated by this machine .
A hot wheels track has a spring loaded launcher. A 100g car is pushed into the launcher, which compresses the spring by 2cm. The cars initial velocity after launching is 3m/s.
