While taking photographs in Death Valley on a day when the temperature is 51.0°C, Bill Hiker finds that a certain voltage applied to a copper wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if...
Two small silver spheres, each with a mass of 12.0 g, are separated by 1.00 m. Calculate the fraction of the electrons in one sphere that must be transferred to the other to produce an attractive force of 3.00e4 N (about 3 tons) between the spheres. (The number of electrons per atom of silver is...
OK So:
2.2t=(m+1/2)(640nm) and 2.2t=m(569 nm)
How do I solve for m?
I tried solving the second equation for t and then plugging it into the first but still no luck...
A thin film of oil (n = 1.10) is located on a smooth, wet pavement. When viewed perpendicular to the pavement, the film appears to be predominantly red (640 nm) and has no component of wavelength 569 nm. How thick is the oil film?
I have tried using 2nt=(m+1/2)wavelength but am having...
Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 80.0° (with respect to the normal to the surface). The apex angle of the prism is 60.0°.
Use the value of n from Figure 35.20, to calculate the following angles.
(a) the angle of refraction at the first...
It says that the reservoir is at 0 degrees, so I didn't think that would necessarily be the final temperature of the argon cause I thought some of the heat from the argon would be exchanged as well...but maybe I am totally wrong here
A rigid tank of small mass contains 50.0 g of argon, initially at 200°C and 100 kPa. The tank is placed into a reservoir at 0°C and is allowed to cool to thermal equilibrium. Calculate the following:
(a) the volume of the tank
(b) the change in internal energy of the argon
(c) the energy...
During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 20.3 atm. Assume that the process is adiabatic and the gas is ideal with (gamma)= 1.40.
(a) By what factor does the volume change?
Vfinal = (ans)*Vinitial
(b) By what factor does...
In a crude model of a rotating diatomic molecule of chlorine (Cl2), the two Cl atoms are 2.00x10^-10 m apart and rotate about their center of mass with angular speed = 1.40x10^12 rad/s. What is the rotational kinetic energy of one molecule of Cl2, which has a molar mass of 70.0 g/mol?
I have...
A thermal window with an area of 6.00 m2 is constructed of two layers of glass, each 4.00 mm thick and separated from each other by an air space of 3.00 mm. If the inside is at 20.0°C and the outside is at -38.0°C, what is the rate of energy transfer by conduction through the window?
i am...
A sample of helium behaves as an ideal gas as energy is added by heat at constant pressure from 273 K to 383 K. If the gas does 23.0 J of work, what is the mass of helium present?
I tried this and think u use m=Q/c*change in T, but not sure where to go from there
Gas in a container is at a pressure of 1.20 atm and a volume of 8.00 m3.
(a) What is the work done by the gas if it expands at constant pressure to twice its initial volume?
wrong check mark J
(b) If it is compressed at constant pressure to one quarter of its initial volume...
