- Janice is grilling a steak for her July 4th barbecue dinner. The steak initially weighs 300 grams and is 25 mm thick. After grilling it for a while, she considers the steak done, and measures it again: it now weighs 215 grams, and is 15 mm thick. For both the cooked and uncooked steak, she uses the thumb-test to determine the done-ness, i.e. she uses her thumb (area ~5cm2) to push down with a force of 5 N. The uncooked steak compresses by 7 mm, and the cooked steak by 2 mm. Calculating elasticity What is the elasticity of the raw steak? Express your answer in Pascals but without including the units in your answer. What is the elasticity of the cooked steak? Express your answer in Pascals, but without including the units.The total consumption of electrical energy in the United States is about 1.0 1019joules per year.What is the average rate of electrical energy consumption in watts?If the population of the United States is 300 million, what is the average rate of electrical energy consumption per person?The sun transfers energy to the earth by radiation at a rate of approximately 1.0 kW per square meter of surface.

- The weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out of existence. Under such extreme conditions, protons and electrons are squeezed to form neutrons, giving birth to a neutron star. Neutron stars are massively heavy - a teaspoon of the substance of a neutron star would weigh 100 million metric tons on the Earth. a) Consider a neutron star whose mass is twice the mass of the Sun and whose radius is 13.3 km. (The mass of the Sun is 1.99-1030 kg.) If it rotates with a period of 2.57 s, what is the speed of a point on the Equator of this star? Submit Answer Tries 0/99 b) What is the value of g at the surface of this star? Submit Answer Tries 0/99 c) Compare the weight of a 1.30-kg mass on the Earth with its weight on the neutron star. How many…Write your answer in 4 decimal places. DO NOT round off intermediate values. The variation of temperature in a plane wall is determined to be T(x)=110-48x where x is in m and T is in °C. If the thickness of the wall is 0.75 m, the temperature difference between the inner and outer surfaces of the wall is °CThe specific heat of copper is 0.093 cal/(g.°C) and the specific heat of gold is 0.031 cal/(g.°C). If 9.5 cal is supplied to one gram of copper and one gram of gold, the RATIO of temperature increase of gold to that of copper is:
- The digital thermometers that we use in the lab today are similar to the ones that we use in our homes, but several years ago scientists used to use glass thermometers that contained a thin column of mercury to measure temperature. Why do you think we no longer use the mercury thermometers in the lab?A closed heavy steel chamber is filled with water at 10°C and at atmospheric pressure. If the temperature of water and the chamber is raised to 40°C, what will be new pressure of water? The coefficient of thermal expansion of the steel is 1.17 x 10-5 per C, assume the chamber is unaffected by the water pressure. Use specific weight of pure water as a function of temperature and pressure for conditions where g = 9.81 m/s².
