The technique known as potassium-argon dating is used to date old lava flows and thus any fossilized skeletons found in them, like this 1.8-million-year-old hominid skull. The potassium isotope 40K has a 1.28 billion year half-life and is naturally present at very low levels. 40K decays by beta emission into the stable isotope 40Ar. Argon is a gas, and there is no argon in flowing lava because the gas escapes. Once the lava solidifies, any argon produced in the decay of 40K is trapped inside and cannot escape.
What is the age of a piece of solidified lava with a 40Ar/40K ratio of 0.31?
An ion accelerated through a potential dif- ference of 177 V experiences an increase in kinetic energy of 6.03 × 10?17 J . Find the magnitude of the charge on the ion.
Write down an expression for the mass of the nucleus
When point charges q1 = +1.7 ?C and q2 = +8.7 ?C are brought near each other, each experiences a repulsive force of magnitude 0.30 N
Consider an LR circuit like that displayed in Figure 6.6 in Activity 2-1 in your lab manual. You measure the current through the inductor as a function of time, What is the total resistance of the circuit

A long rod, insulated to prevent heat loss along its sides, is in perfect thermal contact with boiling water (at atmospheric pressure) at one end and with an ice-water mixture at the other.
A rocket is launched at an angle of 52° above the horizontal with an initial speed of 103 m/s. The rocket moves for 3s along its initial line of motion with an acceleration of 32 m/s2. At this time, its engines fail and the rocket proceeds to move..
