Q. A 45 dB sound wave strikes an eardrum whose area is 4.9 multiplied by 10-5 m2.
(a) How much energy is absorbed by the eardrum per second?
(b) At this rate, how long would it take your eardrum to receive a total energy of 1.0 J?
Q. A 38.00 g bullet is fired with a speed of 180.0 m/s into a 5.000 kg sandbag pendulum that is free to swing. To what maximum vertical height will the pendulum rise?
A 2.10kg snowball is fired from a cliff 8.55 m high with an initial velocity of 11.90 m/s, directed 47.0° above the horizontal. (a) Using energy techniques, find speed of the snowball as it reaches the ground below the cliff. What is that speed (b) i..
A simple harmonic oscillator consists of the block of mass 1.90 kg attached to a spring of spring constant 196 N/m. while t = 3.00 s, position and velocity of the block are x = +0.129 m and v = +3.415 m/s.
Two vectors A and B have the similar magnitude of 100 N (they represent forces of equal strength). What is the magnitude of the resultant vector of A and B if they are parallel and pointing in opposite directions.
Find the minimum volume of concrete (y = 23.6 kN/m3) needed to keep the gate (1 m wide) in a closed position; l = 2 m. Note the hinge at the bottom of the gate. Explain briefly.
A parallel-plate capacitor is charged to an electric potential of 337 V by moving 3.95×1016 electrons from one plate to the other. How much work is done in charging the capacitor.
Calculating magnetic flux, induced current & magnetic field.

A cube of ice is taken from the freezer at -8.7^circ C and placed in a 114 g aluminium calorimeter filled with 329 g of water at room temperature of 20.0 ^circ {rm C}. The final situation is observed to be all water at 15.0^circ C.
A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
How long does the total trip last
Find the typical speed for a tsunami. (Note down that in the open ocean, tsunamis generally have amplitude of less than a meter, allowing them to pass ships unnoticed. As they approach shore, however, water depth decreases and the waves slow down. Th..
