A 2.0kg block of wood sits on a table. A 3.0 g bullet, fired horizontally at a speed of 360m/s , goes completely through the block, emerging at a speed of 250m/s .
What is the speed of the block immediately after the bullet exits?
A particle of charge +15 µC and mass 2.00 10-5 kg is released from rest in a region where there is a constant electric field of +280 N/C
An oxygen bubble at the bottom of a lake 20. m deep has a volume of 1.20 cm^3, calculate the initial pressure inside the bubble at the bottom of the lake
Travelling at a speed of 17.10 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.740. What is the speed of the automobile after 1.81 s have el..
How much higher would the ball have gone in a vacuum. The time constant of an RC circuit is 4.8 s. How much time t is needed for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
Light passes through a 230 lines/mm grating and is observed on a 1.0m wide screen located 1.3m behind the grating. Three bright fringes are seen on both sides of central maximum.
Five clocks are being tested in a laboratory. Exactly at noon, as determined by the WWV time signal, on successive days of a week the clocks read as in the following table.
With a particular grating a doublet of the two wavelengths 731.3 and 732.1 nm is viewed in the third order at 9.3° to the normal, find the grating spacing in nanometers
What is the distance between the centers of the two slits? Describe answer in m.
suppose you are outdoors in the Boundary Water Canoe Area of Northern Minnesota. You have in your hand the empty tube from a roll of paper towel. Outline the mathematical steps you would take to help you achieve an accurate estimate of the stars i..
A cylinder is rolling along the ground without the slipping at 7m/s. It comes to a hill and begins going up. Assume no losses to friction, how high vertically would it go before it stops?
A current with sinusoidal time-dependence, whose peak value is 9.55 A and frequency is 255 cycles per second, Calculate the average power dissipated by the loop
Two identical point charges (q = +6.90 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.45m. A test charge (q0 = -3.20 x 10-8 C), with a mass of 5.20 x 10-8 kg, is released from rest at one of the corners of the s..
