The kiloton, which is used to measure the energy released in an atomic explosion, is equal to about 4.02 x 1012 J (approximately the energy released in the explosion of 1,000 tons of TNT). Recalling that 1 kilocalorie of energy raises the temperature of 1 kg of water by 1 oC and that 4,184 Joules is equal to 1 kilocalorie, then ---- x 108 kg of water initially at 1 oC can be heated up by 60 oC by a 49 kiloton atomic bomb.
You are in a hot air balloon (yes, another balloon problem!) rising from the ground at a constant velocity of 2.70 m/s upward. To celebrate the takeoff, you open a bottle of champagne, expelling the cork with a horizontal velocity of 4.00 m/s rela..
A strip of copper 3.0 cm wide carries a current I = 28.5 A to the right, What is the direction of the average magnetic force on the conduction electrons
Calculate the energy content of 1 kg of natural uranium assuming complete fission. Estimate an average energy per fission. Compare this to the energy in 1 kg of coal (reference all values assumed).
The specific heat of a 98 g block of material is to be determined. The block is placed in a 25 g copper calorimeter that also holds 60 g of water. Determine the specific heat of the block
I am working on a project where we need to find an optimal transfer for a spacecraft from LEO to the L4 LaGrange point in the Earth-Moon system. In order to calculate the delta V for the arrival at the LaGrange point, we need to know the "veloci..
In a muonic atom, the electron is replaced by a negatively charged particle called the muon. What is the shortest wavelength of the Lyman series in a muonic hydrogen atom
A step-down transformer has a turns ratio of 1:10, and its primary is connected across the terminals of a standard 120-V wall socket. What power P is dissipated in the resistor
Mrs. Smith has returned to work and feels well. She does not know why she needs to have periodic blood tests due to the warfarin. What is your explanation to Mrs. Smith.
An unknown mass of tin is heated to a temperature of 202 C. It is placed into 200 g of water which is in a 100 g copper cup initially at 10 C. How much heat is gained by the cup and the water
In the experiment, if the accelerating voltage is 300 V and the radius of the beam path is 3.2 cm, what is the Lorentz force on a single electron
A high-intensity desk lamp is rated at 75 W, but its bulb requires only 9 V. The lamp contains a transformer that converts 110 V household electricity. What is the resistance of the bulb when it is on
Ocean waves pass through two small openings, 21m apart, in a breakwater. You're in a boat 69m from the breakwater and initially midway between the openings, but the water is pretty rough. You row 37m parallel to the breakwater and, for the second tim..
