Determine work should the total external force
A 6100-kg satellite is in a circular earth orbit that has a radius of 2.7x10^7 m. A net external force must act on the satellite to make it change to a circular orbit that has a radius of 5.6x10^6 m. What work must the net external force do?

Suppose that the magnetic field of the Earth were due to a single current moving in a circle of radius 2910 km through the Earth's molten core. The strength of the Earth's magnetic field on the surface near a magnetic pole is about 6.0·10-5
How much fuel would it take to provide this much energy if all the rest energy of the fuel could be transformed to kinetic energy of the spaceship?
An electron moving in a one- dimensional infinite square well of width L is trapped in the n = 5 state. Calculate the probability of finding the electron between x = 0.1 L and 0.4 L to two significant figures.
An inductor with an inductance of 2.90H and a resistor with a resistance of 6.00 Ohms are connected to the terminals of a battery with an emf of 5.00V and negligible internal resistance. A) Find the initial rate of increase of the current in the c
The potential at location A is 419 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 787 V, and when released from rest from this spot, the particle arrives at B
A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 5.0 m/s at the end of 2.0 s. At that instant, the kinetic energy of the system is 100 J and each mass has moved a distance of 5.0 m. Determine
As a 15000 kg jet plane lands on an aircraft carrier, its tail hook snags a cable to slow it down. The cable is attached to a spring with spring constant 60000 N/mIf the spring stretches 30 m to stop the plane, what was the plane's landing speed?
After this time the electric field is turned off and the ball returns to the surface. Find the height in meters which the ball is able to be lifted off the surface. I got .0215 m but it is wrong.
These structures were all unknown until the invention of the electron microscope. Explain why light microscopes cannot reveal them.
At one time, television sets used "rabbit-ears" antennas. Such an antenna consists of a pair of metal rods. The length of each rod can be adjusted to be one-quarter of a wavelength of an electromagnetic wave whose frequency is 65.0 MHz. How long i
