It is the middle of winter and the weatherman forecasts a cold, overcast but dry day with average temperatures of -2°C. However, he highlights the presence of a strong wind with a wind chill factor that will make it feel like -l0°C. What is meant by the term 'wind chill'? How can it be quantified? - discuss its physical o ...continues
A floating spherical shell in water
A hollow spherical iron shell floats almost completely submerged in water. The outer diameter is 54.0 cm, and the density of iron is 7.87 g/cm3. Find the inner diameter. I have no clue how to start or solve this problem. Thanks for the help!
A pressure problem using different areas
A hydraulic press for compacting powdered samples has a large cylinder which is x = 11.8 cm in diameter, and a small cylinder with a diameter of y = 1.96 cm (see figure). A lever is attached to the small cylinder as shown. The sample which is placed on the large cylinder, has an area of 4.09 cm2. What is the pressure on th ...continues
Assuming the density of seawater is 1.03 g/cm3, find the total weight of water on top of a nuclear submarine at a depth of 185 m if its (horizontal cross-sectional) hull area is 3200 m2. In atmospheres, what pressure would a diver experience at this depth? Do you think that occupants of a damaged submarine at this depth could ...continues

Forces, Fields and Energy - Gravitational Fields
The distance between the centres of the Earth and the moon is 3.8 x 10^8 m. Assume that the moon moves in a circular orbit about the centre of the Earth. Estimate the period of the orbit to the nearest day. *Mass of earth = 6.0 x 10^24 kg *1 day = 8.6 x 10^4 seconds *Distance between the centres of Earth and Moon = 3.8 x 10^8 ...continues
Surface Temperature of the Sun
The amount of radiant power produced by the sun is approximately 3.9 x 10^26 watts. Assume the sun is a perfect blackbody sphere with a radius of 6.96 x 10^8 meters, find its surface temperature (in Kelvins).
