You drink a small glass of water that is 99.9999%pure water and 0.0001% some poison. Assume the glass contains about a 1,000,000 million trillion molecules, which is about 30mL. How many poison molecules did you just drink?
A stone with a mass of 2.40-kg is released from rest and falls toward Earth (near the surface of the Earth). Use the impulse-momentum theorem to compute its momentum after falling for4.00 seconds.
An Electromagnetic Car Alarm, Your latest invention is a car alarm that produces sound at a particularly annoying frequency of 3500Hz. What value of inductance should you choose for your car alarm circuit
A string under a tension of 58.5 N is used to whirl a rock in a horizontal circle of radius 2.75 m at a speed of 20.5 m/s on a frictionless surface, What is the breaking strength, in newtons, of the string
A 0.840-kg block oscillates on the end of a spring whose spring constant is k= 42.0 N/m. What is the fractional decrease in amplitude per cycle
A student notes that the length of a 12-inch long ruler held by her teacher (who is moving relative to her) is the same as that of her meter stick (when oriented parallel to his ruler). Find their relative speed
A skier starts from rest at the top of a hill that is inclined at10.4°with the horizontal. The hillside is 245 m long, and the coefficient of frictionbetween snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient..
Suppose in a situation like m1 = 200g were at the 20-cm position and m2 = 100g at the 65-cm position. Would there be a problem in experimentally balancing an equilibrium system with m3 = 50g? Explain. If so, how might the problem be resolved?
The two blocks (m = 30 kg and M = 100 kg) in the figure below are not attached to each other. The coefficient of static friction between the blocks is µs = 0.49, but the surface beneath the larger block is frictionless.
a)What is the angular velocity of the earth (regarded as a particle ) about the sun and b)its average linear speed in its orbit. c) What is the acceleration of the earth with respect to the sun
In a diffraction experiment, light of 600 nm wave length produces a first-order maximum 0.350 mm from the central maximum on a distant screen. A second monochromatic source produces a third - order maximum 0.870 mm from the central maximum when it pa..
A 1.2 MHz ultrasonic beam is used to scan body tissue. If the speed of sound in a certain tissue is 1540 m/s, what size is the smallest detail that can be resolved
