A hydrogen atom consists of a single proton and a single electron. Experimentally it is found that it takes 13.6eV of energy to strip the electron from the proton. Assuming the particles are bound together by the Coulomb force with the e- undergoing circular motion about the proton and that classical physics applies; calculate the size of the hydrogen atom.
Assuming that the pass was thrown at the optimal 45 ^circ angle, evaluate what was the speed at which the ball left the quarterback's hand?
What is magnitude of the linear acceleration of the hoop . Elucidate using Newton's Second Law of Motion, why you can throw a golf ball further than a bowling ball, still though you throw both at the similar angle and with the same amount of force.
A 20.00 kg wood ball hangs from the 1.10 long wires. The maximum tension the wire can withstand without breaking is 600 N. A 0.710 kg projectile travelling horizontally hits and embeds itself in the wood ball. What is the largest speed this projectil..
A boy whirls a stone using an r-m long string in a horizontal circle h m above the ground. The string broke, and the stone flies off horizontally and strike the ground x m away.The velocity with which the stone flies off the circle is? The centrip..
Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health, What is the resistivity of the leaf tissue
What is the least coefficient of friction between the beam and the wall for the beam to remain in static equilibrium.
On your wedding day your lover gives you a gold ring of mass 3.98 g. 59 years later its mass is 3.73 g. On the average how many atoms were abrated from the ring during each second of your marriage? The atomic mass of gold is 177 u.
A damping force acts on the egg, and the amplitude of the motion decreases to 0.101 in a time of 5.00 compute the magnitude of the damping constant b.
A stunt man whose mass is 70kg swings from the end of a 4.50m long rope along the arc of a vertical circle. Assume that he starts from rest when the rope is horizontal, find the tensions in the rope that are required to make him follow his circula..
Find out the energy dissipated by friction. Find the coefficient of kinetic friction between the tires and the road.
This is because of the average release of about 0.03 J per kilogram each year. Show that at 500 C increase in temperature for a thermally insulated chunk of granite takes about 13.3 million years. (Assume that the specific heat of capacity c of g..
