Q. A ship sets out to sail to a point 182-km due north. An unexpected storm blows the ship to a point 158-km due east of its starting point. How far must it now sail to reach its original destination?
Q. If the gas in the container absorbs 275 joules of heat, has 125 joules of work done on it, and then does 50.00 joules of work, what is the increase in the internal energy of gas?
A solid cylinder with mass and radius, rotating with angular speed about an axis throughout its center, is set on the horizontal surface for which the kinetic friction coefficient is.
A circular wire loop of radius 0.50 m lies in a plane vertical to a uniform magnetic field of magnitude 0.40 T. If in 0.10 s the wire is reshaped from a circle to a square, but remains in the plane, what is magnitude of the average induced emf in t..
A car drives north at 42 mi/h for 10 {rm min} and then turns east and goes 5.0 {rm mi} at 62 mi/h. at last, it goes southwest at 30 mi/h for 6.0 {rm min}.
The deflection plates in an oscilloscope are 10 cm by 2 cm with a gap distance of 1 mm. A 100 volt potential difference is suddenly applied to the initially uncharged plates through a 950 ohm resistor in series with the deflection plates.
Agree on the mass of the earth knowing that the mean radius of the moon's orbit about the earth is 248,910 mi and that the moon requires 28.32 days to complete one full revolution about earth.
A discussion of why the ideal gas law is expected to fail at low temperatures and how its failure may affect your estimation of absolute zero.
What is the minimum pressing force that must be used.
solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 x 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and insulating coat on the wire is negligibly thin.
The spheres are given the same electric charge Q and it is found that they come to equilibrium when each string is at an angle of 5 with the vertical. Each string is 30 cm long.
A spherical balloon of volume 4.03 x10^3 cm3 contains helium at the pressure of 1.15 x10^5 Pa. How various moles of helium are in the balloon if the average kinetic energy of the helium atoms is 3.60 x10-22 J.
A spacecraft receding from he earth at 0.97c transmits data at the rate of 1*104pulses/s. At what rate are they received.
At t=0 a grinding wheel has an angular velocity of 20.0 rad/s. It has the constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.20 s. From then on, it turns through an angle 435 rad as it coasts to a stop at cons..
