Q. A rectangular block of ice 14.0 m on each side and 1.4 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m3.
How many penguins of mass 22.0 kg can stand on the ice before they get their feet wet?
Q. Two blocks with masses m1 = 17.3 kg and m2 = 98.6 kg, are free to move. The coefficient of static friction between the blocks is 0.62 but the surface beneath m2 is frictionless.
What is the least force F necessary to hold m1 against m2?
A dynamite blast at a quarry launches a rock straight upward, and 2s later it is rising at a rate of 15m/s. assume air resistance has no effect on the rock, analyse its speed (a) at launch and (b) 5s after launch.
The needle of a sewing machine moves up and down in the same hermonic motion its driving force comes from a rotating wheel that is powered by an electric motor. how do you imagine that theup-and-down needle comapres with the period of the rotating..
Calculate the threshold wavelength, in nm, of a metal if that metal emits an electron with a kinetic energy of 6.32 × 10-19 J when illuminated with light that has a frequency of 1.97 × 1015 Hz.
A lighthouse that rises h1 = 43.6 ft above the surface of the water sits on a rocky cliff that extends $d$ = 20.0 ft from its base, as shown in the figure below. A sailor on the deck of a ship sights the top of lighthouse at an angle of $theta$ = 29...
A wire is stretched between two posts. Another wire is stretched between two posts that are four times as far apart. The tension in the wires is the equal, and they have the same mass.

On a dry day, just after washing your hair to remove natural oils and drying it in detail, run a plastic comb through it. Small bits of paper will be attracted to the comb. Describe why.
A plano convex lens of focal length 16 cm is fixed on the side of the box with convex surface outside an object is placed at 26 cm from the lens find the position of the image while (1) the box is empty (2) field with water.
If a drop is to be deflected a distance = 0.28 by the time it reaches the end of the deflection plate, what magnitude of charge should be given to the drop? Imagine that the density of the ink drop is 1000 and ignore the effects of gravity.
What is Johns resultant displacement
