DOUBLE POINTS
1. For athletes, a focus on body mechanics improves the effectiveness of their efforts.
A.
True
B.
False
2. How does Newton’s second law of physics apply to lifting weights?
A.
Lifting weights requires the proper form and net force.
B.
Without force or motion, the weights are an unbalanced force.
C.
It requires more force to move weights, and this builds muscles.
D.
Weights are an immovable object, and the force is provided by muscles.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

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?
