Suppose a wood fossil was found to be one eighth as C-14 radioactive as the same wood today. How old is it? (answer to the nearest 10 years, i.e. 5010 years, not 5011)
I'm not really sure how to complete this problem or what formula to use, if anyone can help I'd appreciate it, thank you!

The moon takes 27.32 days to go around the Earth. Find the moon's angular velocity and its linear velocity. The moon is 3.84 x 10^8 meters from Earth.
Find: a) the time of the flight b) horizontal displacement c) the maximum height the ball reached
Suppose you are transporting a viscous fluid through a set of 15.0 circular pipes, each with diameter 1.0 cm. If you now replace this set of pipes with one large circular pipe which has a cross sectional...
A vehicle landing on Mars has a vertical velocity toward the surface of 5.5km and a horizontal velicity of 3.5m/s a) what is the speed of the vehicle along the decent path b) what is the angle I...
a bomber flying at an angle 30degrees below the horizontal with 240m/s velocity drops a bomb. A rocket launcher 300m directly below the bomber fires a shell at exactly the same time bomb was dropped...
A car traveling at 10 m/s hits the brakes and comes to a stop in 12 m. What is the car's stopping distance if the speed is doubled?
As a bus accelerates, the passengers on the bus are jolted toward the back of bus. Explain what causes the passengers to be apparently pushed backward.
A) Eric is pushing a lever to lift a 20kg box which lies a distance of .5 meters from the fulcrum. Eric pushes down on the lever with 50N of force, what distance is Eric from the fulcrum? B)...
If a person who exerts 700 N of force has shoes that cover .04 m^2, what is the average pressure exerted on the ground by both feet? One foot?
A constant net force of 15 N acts on an object with a mass of 8 kg. As the mass of the object is increased, what will happen to the acceleration of the object? Explain.
A 900-lb block is being suspended and held stationary by two steel cables as shown. The first cable (to the left of the block) makes a 70 degree angle with the horizontal, while the second cable...
