The director James Cameron recently went in a submersible 1 man submarine to the bottom of the Mariana trench. Find out how deep he went and determine the percent change in water density due to depth, using the bulk modulus. Consider only pressure changes.
The diagram below depicts a cross section of coaxial conductor with an inner wire of diameter di and an outer conducting sheath of inside diameter do, and some material placed in the space between the two wires.
A parallel-plate capacitor with plates of area 441 cm2 is charged to a potential difference V and is then disconnected from the voltage source. When the plates are moved 5.02 mm farther apart, the voltage between the plates increases by 81.0 Volts. W..
Suppose you are old and as a last act want to see for yourself what it is to cross an event horizon (knowing you cannot come back). To get there, though, you have to survive the tidal forces.
A system receives 107 joules in the form of heat energy in a specified process and it produces work of 4*10^6 joules. The system velocity changes from 10km/s to 25 km/s and its elevation changes from 20m to 12m. The mass of the system is 50 kg. Deter..
A very long solenoid of radius a and height h has N closely wound turns of coil. Suppose there is an increasing current I(t) that runs through the coils. Consider a point P inside the solenoid (i.e. at r
A magician pulls a tablecloth from under a 200 g mug located 30.0 cm from the edge of the cloth. The cloth exerts a friction force of 0.140 N on the mug, and the cloth is pulled with a constant acceleration of 2.90 m/s2. How far does the mug move rel..
Air which may be treated as an ideal gas, is compressed from 100 kpa to 1500 kpa in a quasisatatic manner so that it obeys the relation ....pV^1.3 = constant determine the amount of work necessary to compress 100kg of air. The initial temperature ..
A 40 kg sheave a OF RADIUS R=350 mm. and cenral radiusof gyration k=250 mm carries a 160 kg load b and is suspended by a cable and a spring of modulus k=1.2 kN/m. if the system is relased from rest in the positon show the spring is stretched 100 mm d..
For the beam and loading shown, write the equation of he shear and bending-moment curves and determine the magnitude and location of the maximum bending moment
You are in charge of evaluating the safety (hazard) of a low water crossing. Traffic surveys show that the "Aaverage"vehicle using the crossing is semi-rectangular in shape (10 ft long, 5 ft wide, and 4.0 ft high - not including the distance from the..
An object moves 2.95m in the +x-direction under the influence of a 125N force directed 52 degrees above the x-axis. Find the work done on the object
A 24kg chimpanzee hangs from the end of a horizontal, broken branch of length L0 = 1.4m , What is the shear modulus for this branch
A body is moving with velocity of 8m/s. After 5 Seconds the velocity of the body becomes 18m/s. Find the acceleration of the body
Under ambient conditions (T=300K), the intrinsic electron concentration of silicon is 1.45*10^10 cm^-3. Calculate the band gap energy of the semiconductor
A worker pushes a sled with a force of 50 N over a level distance of 7.0 m. what net work is done on the sled
For a spherical celestial object of radius R, acceleration due to gravity g at a distance x from the center of the object is g = g0R2/x2, where g0 is the acceleration due to gravity at the object's surface and x > R.
For the following questions, express your answers in terms of q. (a) How much charge ends up on sphere C? (b) What is the total charge on the three spheres before they are allowed to touch each other? (c) What is the total charge on the three sphe..
