1. If one could repeat the same experiment in the lab located on the Moon (different weight of the measured objects), then would the density result be different? If yes, then explain how much different. If not, then why the result would be same?
2. Consider two objects that have exactly the same shape and dimensions. The first object has a larger density than the second object. Both object are completely immersed in water. Is the buoyant force acting on the first object greater than or equal to the buoyant force acting on the second object? Explain.
A smooth block on a frictionless surface is attached to a spring, pulled to the right a distance of 4 cm and the released. Three seconds later it returns to the point of release.
Water flowing through a garden hose of diameter 2.73 cm fills a 22.0 L bucket in 1.20 min. What is the speed of the water leaving the end of the hose?
Space probes require power systems that can remain functional over long periods of time. One innovative design for a small electrical power source uses the energy released by the alpha decay of curium-244.
Find the magnitude of the resultant displacement from the starting point. Answer in Units of paces.
Mitch is driving the Batmobile (which he stole). He is driving at a constant velocity of 40 m/s. What is the acceleration of the Batmobile
Jet propulsion is when a jet of fluid is used to propel an object. This is an example of conservation of momentum because
A box is pushed across the floor against a constant frictional force. The box is pushed across the room to the east in 30 seconds and returned to its starting point (pushed to the west) in 60 seconds.
By accident, a large plate is dropped and breaks into three pieces. The pieces fly apart parallel to the floor, with v1 = 2.80 m/s and v2 = 1.85 m/s. As the plate falls, its momentum has only a vertical component, and no component parallel to the flo..
An isolated conductor of arbitrary shape has a net charge of +9.5 x10-6 C. Inside the conductor is a cavity within whichis a point charge q = +2.4 x 10-6 C. InCoulombs, what is the charge on the outer surface of the conductor?
A counterweight of mass m = 4.20 kg is attached to a light cord that is wound around a pulley, compute the net torque on the system about the axle of the pulley
an object is 19 cm in front of a diverging lens that has a focal length of -9 cm. how far in front of the lens should
A rock is tossed straight up with a velocity of 40.0 m/s.When it returns, it falls into a hole 11.5 m deep. What is therock's velocity as it hits the bottom of the hole?
