Oxygen and nitrogen are the two most common gasses in air. Both are diatomic. Knowing this, define why the spectrum of air is so complicated. (Think about the electrons moving from one energy level to another in the Bohr atom and expand this to the electrons in two atoms bound together.)
Two blocks, each of mass m = 1.4 kg, are pushed along the horizontal surface of a table by a horizontal force P of magnitude 4.7 N, Find the frictional force acting on the upper block
at some instant the velocity components of an electron moving between two charged parallel plates are vx 1.10 x 105 ms
A certain wire stretches 0.980 cm when an outward force of magnitude F is applied to each end. The same force is applied to a wire of the similar material however with tree times the diameter and with three times the length. By how much will the seco..
A 260(omega) resistor is in series with a 9.50×10?2H inductor and a 0.56 (mu)F capacitor. Compute the impedance of the circuit at a frequency of f1 = 500 Hz
A satellite of mass320kg is in a circular orbit around the Earth at an altitude equal to the Earth's mean radius. Calculate the gravitational force acting on it
On her return trip, she drives half the time at 43.0 and half the time at 74.0. What is Julie's average speed on the way to Grandmother's house. What is her average speed on the return trip
A 75 kilogram skier rides a 2830 meter long lift to the top of a mountain. The lift makes an angle of 14.6o with the horizontal. Determine the change in the skier gravitational potential energy
A projectile is fired at v0 = 394.0 m/s at an angle of θ = 64.2o with respect to the horizontal, How far will the projectile travel in the horizontal direction, R
secret agent samantha bond 51.00 kg has just ignited her jet powered skis at the foot of a 10.0 degree slope that rises
a spherical shell has inner radius rin and outer radius rout. the shell contains total charge q uniformly distributed.
A bullet of mass 8.80 x 10-3 kilogram, moving at 1250 m/s impacts a tree stump and penetrates 4.00 centimeter into the wood before coming to rest. If the similar force acted on the bullet and it had the equal impact speed but half the mass, calcul..
Compute the temperature at which a tungsten filament that has an emissivity of 0.35 and a surface area of 3.0 10-5 m2 will radiate energy at the rate of 15 W in a room where the temperature is 13°C.
