The mass at time t of a radioactive substance is m (t) = m (0) ekt, where m (0) is the initial mass and k=-0.000135. The mean life M of an atom in this substance is M=-k∫∞0tektdt=

A boeing 727-200 jet taking off from lansing airport accelerates from rest for 31.0 s before leaving the ground. its acceleration is 2.19 m/s2. assuming that the acceleration is constant, calculate the plane's speed at take off.

A ray of light bends upon entering a new medium. What is this phenomenon called?

What is the persistent fear of snow falling

Tom stops using a new skin cream for five days to determine if the cream is the cause of a recent rash. What stage of the scientific method is Tom using?

Use your observations to determine qualitatively how the strength of the electric interaction between charged objects depends on the distance between them. Explain your reasoning (this is trickier than it might seem at first).

Far from any other masses, two masses, m1 and m2, are interacting gravitationally. The value for the mass of m1 suddenly doubles. What happens to the value of the gravitational force that mass m2 exerts on mass m1?

Which of the outer planets are most like Earth? How?

The pressure inside a champagne bottle can be quite high and can launch a cork explosively. Suppose you open a bottle at sea level. The absolute pressure inside a champagne bottle is 6 times atmospheric pressure; the cork has a mass of 7.
