Lightning can be studied with a Van de Graaff generator, which consists of a spherical dome on which charge is continuously deposited by a moving belt. Charge can be added until the electric field at the surface of the dome becomes equal to the dielectric strength of air. Any more charge leaks off in sparks as shown in the figure below. Assume the dome has a diameter of 40.0 cm and is surrounded by dry air with a "breakdown" electric field of3.00 106 V/m.
(a) What is the maximum potential of the dome?
kV
(b) What is the maximum charge on the dome?
C
In the experiment you will observe well defined "bumps" in the string, and you will measure their length. What is the relation between this length and the wavelength of the wave
Use the value of the Sun's luminosity (3.90×10^26 watts, or 3.90×10^26 joules per second) to calculate what mass of hydrogen the Sun will convert into helium during its entire main-sequence lifetime of 1.2×10^10 years.
Compute the y-component of acceleration
A massive steel cable drags a 25-kg block across a horizontal, frictionless surface. A 90.0 N force applied to the cable causes the block to reach a speed of 4.5m/s in 1.5s. What is the difference in tension between the two ends of cable.
Compute the force of gravity between a newborn baby (mass = 4 kg) and the planet Mars (mass = 6.4 x10^23 kg), when Mars is at its position closest to Earth (distance = 8.0 x10^10 m).
A 0.5970-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water, calculate the final temperature of the puddle once it settled to equilibrium
A 500 turn solenoid with a length of 20 cm and a radius of 3.0 cm carries a current of 3.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the same radius as the solenoid. Find when the curre..
A river has a steady speed of 0.25m/s. A student swims upstream a distance of 1 km and swims back to the starting point. If the student can swim at the speed of 1.4m/s in still water.
During an adiabatic process, the temperature of 3.62mol of a monatomic ideal gas drops from 460C to 215C a) Find the work done by the gas. b)Find the heat the gas exchanges with its surroundings. c)Find the change in its internal energy.
define How long are the skid marks. calculate the time it takes the sled to go 21 m down the slope.
A gas expands from I to F. The energy added to the gas by heat is 442 J when the gas goes from I to F along the diagonal path. What is the change in internal energy of the gas.
