2. A refrigerator has a coefficient of performance equal to 6.00. The refrigerator takes in 150 J of energy from a cold reservoir in each cycle.
(a) Find the work required in each cycle.
J
(b) Find the energy expelled to the hot reservoir.
compute how much charge must be placed on the surface of a sphere of radius 0.31 m for the electric potential just above the surface to be 100 V. Assume that the charge is uniformly distributed.
What is rms speed of the atoms at temperature
What is the temperature of the outside air. What are the components of the displacement vector from camp to summit? What is its magnitude? select the x axis east, y axis north, and z axis up.
compute the magnitude of the magnetic force exerted on it.
An electric vehicle starts from rest and accelerates at a rate of 1.7 m/s2 in a straight line until it reaches a speed of 27 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 until it stops. (a) How much time elapses from start to stop? (..
Iced tea is made by adding ice to 2.4 kg of hot tea, initially at 70?C. How many kg of ice, initially at 0?C, are required to bring the mixture to 10?C? (Lf = 3.33×105 J/kg, cw = 4,186 J/kg•? C)
An insulated Thermos contains 110cm3 of hot coffee at 90 °C. You put a 12g ice cube at its melting point to cool the coffee. By how many degrees has the coffee cooled once the ice has melted and equilibrium is reached? Care for the coffee as thoug..
A test charge of +2*10^-7 C is located 5cm to the right of a charge +1*10^-6 C and 10 cm to the left of a charge -1*10^-6 C. The three charges lie on a straight line
A cylindrical container 1.1 tall contains mercury to a certain depth. The rest of the cylinder is filled with water.If the pressure at the bottom of cylinder is two atmospheres, what is the depth.
A 4.6-{\rm Hz} wave with an amplitude of 20cm and a wavelength of 30cm travels along a stretched horizontal string. How far does a given peak on the wave travel in a time interval of 0.55s ? The answer is dpeak = .76m. How would your answer to par..
A 300kg piano slides 4.10 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.4. Determine the force exerted by the man.
A ranger in a national park is driving at 41km/h when a deer jumps onto the road 66 m ahead of the vehicle. After a reaction time of t s, ranger applies the brakes to produce an acceleration of -3.20m/s2. What is the maximum reaction time allowed ..
