As you all know, the Hydrogen atom consists of one electron and one proton. In the Bohr model of the Hydrogen atom, the electron orbits the proton in a circular orbit of radius 0.529 E-10 m. This radius is known as the Bohr Radius.
Calculate the smallest amount of kinetic energy the electron must have in order to leave its circular orbit and move to infinity far from the proton?
A 30.0 capacitor initially charged to 30 is discharged by a 1.40 resistor. How long does it take to reduce the capacitor's charge to 2.00.
A child slides across a floor in a pair of rubber-soled shoes. Thefriction force acting on each foot is 20.0 N. The footprint area ofeach shoe sole is 14 cm2, and the thickness of eachsole is 5 mm. Find the horizontal distance by which the upper a..
Assume that the temperature of the bullet doesn't change appreciably, how much ice is melted as a result of the collision.
Quarks carry spin 1/2. Three quarks bind together to make a baryon (such as the proton or neutron); two quarks (or more precisely a quark and an anti-quark) bind together to make a meson (for example the pion or the kaon). Suppose the quarks are i..
A 1.00-kg beaker containing 1.80 kg of oil (density = 916 kg/m3) rests on a scale. A 1.90-kg block of iron is suspended from a spring scale and is completely submerged in the oil. Determine equilibrium readings of both scales.
At what speed does the speed of the ball change relative to the cab floor (sign and magnitude)?
what is the smallest value d can have before the string breaks?
