ii. Superior/inferior trochoid with rolling circle radius 20 mm and generating circle radius 25 mm/ 15 mm respectively.
A certain lightbulb has a tungsten filament with a resistance of 18.0 when cold and 138 when hot. Find the temperature of the hot filament
A blue car with mass mc = 442 kg is moving east with a speed of vc = 22 m/s and collides with a purple truck with mass mt = 1213 kg that is moving south with a speed of vt = 12 m/s. find the magnitude of the initial momentum of the car
A mass m1 = 3.8 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 5.5 kg which hangs freely from the string, What is the tension in the string as the block falls
From the difference in mass of a hydrogen atom (Appendix B) to the mass of a proton and an electron (Table 1.5), estimate the binding energy of the electron in the hydrogen atom. Compare this to the ionization energy of the ground state electron a..
A ball is traveling horizontally over a volleyball net when a player "spikes" it, driving it straight down to the ground. What is the magnitude of the impulse from the spike
An electron is located on a pinpoint having a diameter of 5.30 µm. What is the minimum uncertainty in the speed of the electron
A duck has a mass of 2.6 kg. As the duck paddles, a force of 0.11 N acts on it in a direction due east. In addition, the current of the water exerts the force of 0.12 N in a direction of 44° south of east. When these forces begin to act, the velocity..
The larger the mass of a star, the shorter its Main Sequence lifetime becomes. Estimat the Main Sequence lifetime of a star with a mass of 6 Msolar
How much higher would the ball have gone in a vacuum. The time constant of an RC circuit is 4.8 s. How much time t is needed for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
