(II) V is a vector 14.3 units in magnitude and points at an angle of 34.8" above the negative x axis (a) Sketch this
vector. (b) Find V, and V,. (c) Use V, and V, to obtain
(again) the magnitude and direction of V. [Nore: Part (c)
is a good way to check if you've resolved your vector
Correctly.

Ingrid wrote the hypothesis below. if the temperature of a liquid increases, the density of the liquid decreases because the particles move farther apart. what are the variables in her hypothesis?

What happens to atoms and chemical bonds during a reaction?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
