2) The amount of blood in a person’s body depends on their body weight. A person weighing 120 pounds has about 20 pints of blood in their body.
Which equation below represents the relationship between pints of
blood, b, to a person’s weight, w?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

The energy produced as a result of this flow of electrons from atom to atom is called

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
