Two identical springs (neglect their masses) are used to "play catch" with a small block of mass 110g (see the figure ). Spring A is attached to the floor and compressed 10.0cm with the mass on the end of it (loosely). Spring A is released from rest and the mass is accelerated upward. It impacts the spring attached to the ceiling, compresses it 2.00cm , and stops after traveling a distance of 30.0cm from the relaxed position of spring A to the relaxed position of spring B.
Determine the spring constant of the two springs (same since they are identical).
Assuming no heat loss to the surrounding environment, determine the minimum duration of time necessary for a 100 W aquarium tank heater to raise the temperature of 20.0 gallons of water by a difference of 10.0°C.
Kahlinium is an H-like atom consisting of an electron and the positive Casimir particle, what would be the wavelength of the first line of the Lyman emission series for this atom
The dipole moment of a water molecule in liquid water is 6.2×10-30 C•m, and the effective diameter of the water molecule is 2.8×10-10 m. In an earlier homework problem the effective dipole charge separation for water was calculated as 1.9×10-11 m.
