Q. The concrete wall of a building is 0.11 m thick. The temperature inside the building is 23.2°C, while the temperature outside is 0.0°C. Heat is conducted throughout the wall. When the building is unheated, inside temperature falls to 0.0°C, and heat conduction ceases. However, the wall does emit radiant energy when its temperature is 0°C. The radiant energy emitted per second per square meter is the same as the heat lost per second per square meter due to conduction. What is the emissivity of wall?
A steel aircraft carrier is 370 m long when moving through the icy North Atlantic at a temperature of 2°C. By how much does the carrier lengthen when it is travelling in the warm Mediterranean Sea at the temperature of 21 °C.
A ship sets out to sail to a point 148 km due north. An unexpected storm blows the ship to a point 148 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive angl..
The radius of Venus's orbit is 0.72 times that of Earth's orbit. How much stronger is the Sun's gravitational field at Venus than at the earth.
What is the electric potential between the two terminals. A capacitor is formed by placing a 20 cm long charge carrier charged to +10nC placed 5cm away from and parallel to a 20 cm long charge carrier charged to -10 nC. Find the electric field at 1..
A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one o..
