Physics Grade 11 Newton's Law of Gravitation
Calculate Jupiter's mass given the acceleration due to gravity at the north pole is 28.328 m/s^2 and the radius of Jupiter at the pole is 66,850 km.
M calculated = kg
There is a +4.00nC at the origin. A second charge is placed at(-4.00 cm, 0). this second charge reduces the electrical field tozero at the point (+10.0cm, 0). what is the value of the charge?
Two converging lenses have the same focal length of 5.00 cm. They have a common principal axis and are separated by 23.2 cm.
A simple harmonic oscillator has a potential energy of 25x2 Joules, a kinetic energy of 0.5v2 Joules where x is the displacement in meters and v the instantaneous velocity in m/s. determine the maximum instantaneous velocity
Two small concentric conducting shells produce a radically outward electric field of magnitude 49,000 N/C a distance of 4.10 meter from the center of the shells. compute the amount of charge on the outer surface of the larger shell
A rod of length 30.0 cm has linear density (mass per length) given by l 5 50.0 1 20.0x, What is the mass of the rod
The pilot of an airplane executes a loop-the-loop maneuver in a vertical circle. What is the pilot's apparent weight at the lowest point if his true weight is 160 lb
A refrigerator has a coefficient of performance of 2.10. Each cycle it absorbs 3.40 104 J of heat from the cold reservoir. How much mechanical energy is required each cycle to operate the refrigerator?
A block is released from rest at the top of a frictionless ramp (inclined plane) that makes an angle of 25° with respect to horizontal. What is the length of the ramp D1
A Geiger counter registers a count rate of 8,000 counts per minute from a sample of a radioisotope. What is the half-life of the radioisotope
Oscilloscopes are found in most science laboratories. Inside, they contain deflecting plates consisting of more-or-less square parallel metal sheets, what is the strength of the electric field between the plates
A twelve turn coil 10 cm in diameter has its axis parallel to a magnetic field of 0.5 T which is produced by a nearby electromagnet. The current in the electromagnet is cut off, and as the field collapses, an average emf of 8 V is induced in the c..
A parallel-plate capacitor has circular plates and no dielectric between the plates. Each plate has a radius equal to 2.3 cm and the plates are separated by 1.1 mm. Charge is flowing onto the upper plate (and off of the lower plate) at a rate of 5..
