Kinetic energy=1/2mv^2
=1/2(142*10^-3)(42.9)^2=130.6=131J
Answer:
C is the best answer because we all know that clock is part of our daily lives but we don't know the about its background
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
Using the equation for period length for a pendulum, you get 32.829 meters.
