3b. grace drives her car with a constant speed
of 56 miles per hour. how long will she take
to travel a distance of 224 miles?

Where do magnetic lines of force enter earth?

What is the freezing point of radiator fluid that is 50% antifreeze by mass? kf for water is 1.86 ∘c/m.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
