An electron gun inside a computer monitor sends an electron toward the screen at a speed of 1.20 × 108 m/s. If the mass of the electron is 9.109 × 10–31 kg, illustrate what is the magnitude of its relativistic momentum?
What was the speed of the car before impact
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
What speed limit should be posted for the curve. How long (in {rm ns}) does it take light incident vertical to the glass to pass through this 9.0 {rm cm}-thick sandwich.
A generator uses a coil that has 140 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), find out the length of the..
A 0.015 kg bullet traveling horizontally at 400.2 m/s strikes a 4.1 kg block of wood sitting at the edge of a table. The bullet is lodged into the wood. If the table height is 1.2 m, how far from the table does the block hit the floor.
Two negative chrges are placed on the x-axis. A charge of -11.4 micro coulmbs is placed at x=0cm and another charge of -5.4 m/C is placed at x=119cm. where on the x axis is the total field between the two charges zero? Answer in cm
A person carries a long pole of mass 10kg and length 3.40 m at the angle of 60 degrees. Find the magnitude of the torque on the pole by reason of gravity.
A firefighter at a distance d from a burning building directs a stream of water from a fire hose at angle θi above the horizontal as shown in Figure. If the initial speed of the stream is vi. At what height h does the water strike the building?
Three astronauts, propelled by jet backpacks, push and guide a 114 kg asteroid toward a processing dock, exerting the forces, with F1 = 32 N, F2 = 52 N, F3 = 39 N, θ1 = 30°, and θ3 = 60°. What is the (a) magnitude and (b) angle (measured relative ..
In a certain region of space, the electric field, E, is constant in direction (say horizontally in the +x-direction), but its magnitude decreases.
A sled weighing 1.0 X 10^2 N is held in place on a frictionless 20.0 degree slope by a rope attached to a stake at the top. The rope is parallel to the slope. What is the normal force of the slope acting on the sled.
