The sun radiates energy at the rate of 6.5 x 10 to the power of 7 w/m squared.Assuming that the sun radiates as a black body(which approximate true), find its surface temperature.
A copper ball 2 cm in radius is heated in a furnace to 400 degree celsius. if its emissivity is 0.3, at what rate does it radiates?
Nitric acid reacts with silver metal: 4HNO3+3Ag yields NO+2H2O+3 AgNO3. Calculate the number of grams of NO formed when 10.8 g of Ag reacts with 12.6g of HNO3.
) A 4.8 kg block attached to a spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0 s, the block has a displacement of -0.90 m a velocity of -0.80 m/s and an acceleration of +2.9 m/s^2. The force constant of the spring is closest to:
The diameter of an electric cable is normally distributed, with a mean of 0.9 inch and a standard deviation of 0.02 inch. What is the probability that the diameter will exceed 0.92 inch? (You may need to use the standard normal distribution table. Round your answer to three de...
Suppose that people's heights (in centimeters) are normally distributed, with a mean of 170 and a standard deviation of 5. We find the heights of 60 people. (You may need to use the standard normal distribution table. Round your answers to the nearest whole number.) (a) Ho...
