Q. A tank of water 3.00m deep sits on a table 1.00 m tall. A hole is located 2.0m from the bottom of the tank. Water flows out of hole and strikes the ground. Where does it strike the ground?
Q. An unstable nucleus with a mass of 19.0 x10-27 kg initially at rest disintegrates into three particles. One of the particles, of mass 4.1 x10-27 kg, moves along the positive y-axis with a speed of 9.0 x10^6 m/s. Another particle, of mass 7.5 x10-27 kg, moves along the positive x-axis with a speed of 1.0 x10^6 m/s. (Assume that mass is conserved.)
Find out the third particle's speed.
Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. What is the translational speed of the frozen juice can while it reaches bottom.
A particular organ pipe can resonate at 231 Hz, 385 Hz, and 539 Hz, but not at any other frequencies in between. Is it an open or a closed pipe? What is the fundamental frequency of this pipe.
A convex spherical mirror with a radius of curvature of 14.5 cm creates a virtual image one half the size of the real object. Where is the object.
A bat emits a sound whose frequency is 91.20 kHz. The speed of sound in air at 20 degrees Celcius is 343m/s. However the air temperature is 38.8 degrees Celcius, so the speed of sound is not 343m/s. imagine that air behaves like an ideal gas, and ..
A 0.27 kg rock is thrown perpendicularly upward from the top of the cliff that is 32 m high. When it hits the ground at the base of cliff, the rock has a speed of 29 m/s. suppose that air resistance can be ignored, find out A) initial speed of the ro..
The train comes to a stop 6.0 m from the point at which it was released. What is the magnitude of train's acceleration after its wheel begins to stick.
he driver finds that the car bounces up & down with maximum amplitude when he drives at a speed of 4.2 m/s (approx 9.4 mph). The car then stops & picks up three more 110 kg passengers. By how much does the car body sag on its suspension when these ..
