Which is a balanced equation for this reaction? a. fe + h2so4? fe2(so4)3 + h2 b. 2fe + h2so4? fe2(so4)3 + h2 c. fe + 3h2so4? fe2(so4)3 + 3h2 d. 2fe + 3h2so4? fe2(so4)3 + 3h2

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
