According to Keplers 3rd Law, how would a planets orbital period change if the planets...
1. Mass halved?
2. Eccentricity doubled?
3. Distance from the sun quadrupled?
A broad source of light (λ=589 nanometer) illuminates normally two glass plates 12 centimeter long hat touch at one end, Find how many bright fringes appear over the 12 centimeter distance
The angular speed of an automobile engine is increased at a constant rate from 1100 rev/min to 4200 rev/min in 16 sec. Find its angular acceleration in revolutions per minute-squared
A cylinder with a piston contains 0.250 mol of oxygen at 240000 pascal and 355 kelvin. The oxygen may be treated as an ideal gas. The gas first expands isobarically to twice its its original volume. It is y then compressed isothermally back to its..
Two long, straight wires are parallel and are separated by a distance of d = 0.230 m, The top wire in the sketch carries current I1 = 3.80 A, toward the right, and the bottom wire carries current I2 = 7.00 A, what are the magnitude and direction of t..
The largest fusion bomb ever detonated (called the Tsar Bomba) was tested by the Soviet Union in 1961. How many kilograms of matter were converted to energy
The sensor in the torso of a crash-test dummy records the magnitude and direction of the net force acting on the dummy. If the dummy is thrown forward with a force of 570N while simultaneously being hit from the side with a force of 2400-N, what f..
An alpha particle (charge +2.0e) is sent at high speed toward a gold nucleus (charge +79e). What is the elctrical force acting on the alpha particle when it is 2.0e-14m from the gold nucleus?
A force of 400.0 N is exerted on a 1,250 kg car while moving a distance of 3 m. How much work was done on the car
A laser beam impinges on the top surface of a 2cm thick parallel glass which has an index of infraction of n=1.50 at an angle of 35 degrees. How long is the path during the glass?
Figure 19-26 shows two paths that may be taken by a gas from an initial point i to a final point f. Path 1 consists of an isothermal expansion (work is 60 J in magnitude), an adiabatic expansion (work is 38 J in magnitude), an isothermal compression ..
What is modify in frequency ff - fi
an alternating rc circuit is constructed from a 331+/- 3 uF capacitor and a 15+/-.15 ohm resistor connected in series with an alternating voltage source that has a frequency of 100 Hz. Determine phase angle between the supplied EMF and the current..
