a Person weights 30 Lb on the moon where g=5.32 determine
a) the mass of the person and
b) the weight of the person.
A 2.80x 10^2 W electric immersion heater is used to heat a cup of water. The cup is made of glass and its mass is 3x10^2 g. It contains 250g of water at 15°C.
A mass (3kg) on a string lies on a horizontal frictionless surface tied to a central point. How fast can the mass move around the circle without breaking the string
A long, straight wire runs along the y-axis. The wire carries a current in the positive y-direction that is changing as a function of time according to i = 8 A + (0.2 A/s)t. A loop of wire is placed in the xy-plane near the y-axis. The loop has di..
The wavelength of the laser beam used in a compact disc player is 649 nm. Estimate the spacing between the slits of the grating
You travel from "point" Columbia to St. Louis in a car moving at a constant speed of 60 km/h. Then you travel back from St. Louis to Columbia the same distance moving at a constant speed of 120 km/h.
A positively charged particle of mass 7.60 10-8 kg is traveling due east with a speed of 40 m/s and enters a 0.39-T uniform magnetic field. compute the magnitude of the magnetic force acting on the particle
A spherical shell has an outside radius of 2.6cm and an inside radius of a. The shell wall has uniform thickness and is made of a material with density 4.70g/ cm3. The space inside the shell is filled with a liquid having a density of 1.23g/cm3.
A 10,000 kg railroad car is rolling at 1.5 m/s when a 4000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded
A very narrow hole is drilled all the way through the Earth (through its center) and evacuated (i.e. there is neither air resistance nor friction). A small object of mass m is dropped into the hole at the surface.
A can of soup has a mass 420 g, height 13 cm, and diameter 5.6 cm. Calculate the moment of inertia of the can if it takes 1.5 s to reach the bottom of the incline
A tank circuit in a radio transmitter is a series RCL circuit connected to an antenna. compute maximum inductance of the tank circuit
Relativistic reversal of events. Figures 37-25a and b show the (usual) situation in which a primed reference frame passes an unprimed reference frame, in the common positive direction of the x and x' axes, at a constant relative velocity of magnit..
