Molecular Orbital Theory vs Valence Bond Theory: Conductivity
How much tension does your bicep exert to support not only your arm, but also a 12N weight in your hand?
The smaller cylinder has mass m and radius b. A small perturbation sets the small cylinder in motion, causing it to roll down the side of the large cylinder.
A beam of electrons traveling with speed 7 × 10 ^7 m/s passes through a slit of width 1 × 10 ^(-5) m. Because of the uncertainty in the lateral position
Suppose optical radiation (of wavelength 2.6 × 10^-7 m) is used to determine the position of an electron to within the wavelength of the light.
If we have a uniform diving board, with a length 5.0 m and mass 54 kg, is supported at two points; one support is located 3.4 m from the end.

If its initial angular speed was 3410 rpm, what is the magnitude of its angular deceleration?
What torque must be applied to this object to give it an angular acceleration of 1.27 rad/s2 if it is rotated about the x axis?
Physicists use laser beams to create an "atom trap" in which atoms are confined within a spherical region of space with a diameter of about 1 mm.
Distinguish risk and uncertainty. Distinguish a priori and statistical probabilities.
A series RCL circuit is a resonance and contains a varible resistor that is set to 175 ohms. The power delivered to the circuit is 2.6 W.
