Starting from Newton’s law of universal gravitation, show how to find the speed of a man-made satellite in its orbit around the earth from the earth-satellite distance of 3.5 × 108 m and the earth’s...

Jupiter has a radius of about 10.0 earth radii, and a mass 325 times the Earth’s mass. Estimate the gravitational field on the surface of Jupiter compared to that on the Earth. Show your work.

The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 2.23 105 Pa (32...

2. A 75.0 kg astronaut is training for accelerations that he will experience upon reentry. He is placed in a centrifuge (r = 10.0 m) and spun at a constant angular velocity of 15.3 rpm. Answer...

1. A 22 kg child on a sled slides down a 100 m long, 13 m high hill. If the coefficient of friction between the sled and the snow is .05, how fast is the child going at the bottom of the hill? 2...

1. A ball is dropped from an unknown height and allowed to bounce until it comes to rest. Each bounce is lower than the previous one. Does the law of conservation of energy hold true for...

I'm really confused. This makes no sense. How does a north pole in a magnet point to the Earth's magnetic North in the Arctic when the same poles are supposed to repel

By how much must their temperatures be raised in order for the brick and the can to have exactly the same height?

A 1.5 kg book is held against the wall by an applied force. The applied force is 60° above the horizontal. Given that the static coefficient of friction between the block and the wall of 0.65, determine: a)...

A block of mass m is pulled by force F (originating from the top left corner of the block) in an upward direction with *angle θ above the horizontal, across a rough surface...

The reaction occurs at 900 mmHg and the formula for the reaction is: C2H5OH+O2===> CO2+H2O

i need to know the velocity of the man that has ran a 5k in 32 minutes in meters/

How do I solve this AP Chemistry problem?

What volume will 1.23g of CO2 occupy at 45°C and 678 mmHg?

Suppose that a spring has a natural length of 20 cm, and that 7 J of work is needed to stretch from a length of 30 cm to 50 cm. How far beyond its natural length will a force of 28 N keep the spring...

In the investigation of the electronic absorption spectrum of a particular element, it is found that a photon having a wavelength of 500nm provides just enough energy to promote an electron...

The horizontal boom supporting the sign is of uniform construction and weighs 50 N. If the sign weighs 150 N, the angle between the force exerted by the hinge on the boom and the boom is approx...

a) a 0.50 kg ball thrown straight up with a velocity of 30 m/s. b) a 2000 kg railway car moving south at 10 m/s. c) an electron of mass, 9.1 x 10-31 kg moving at a velocity of 1 x 107 m/s...
