A spring (k=0.02) is displaced by 0.5 mm. What is the mass of the object (assume we are on Earth)

If 21.2 kcals of energy is released by this reaction, how many kj does the reaction release? (1 cal 4.184 j)

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
