400

According to the Law of Conservation of Mass, Products must have

What is the same mass as the reactant

400
on a graph showing speed, a straight, slanted, upward line represents
an object moving at constant speed

A race car is travelling 300 miles in 2 hours. Is this enough information to tell the car's velocity? Why or why not?
no, the car's direction of motion is not given
400
is the Earth experiencing acceleration?
Yes, it is constantly turning on its axis (rotation) and moving around the sun (revolution)
400
what do we call the x and y axis values?
What are coordinates
500

Most of the mass of an atom is located here 

nucleus

500
on a graph showing speed, a horizontal line represents
an object that is at rest
500
Why could it be important to use velocity instead of speed when you describe how a storm is moving?
In order to keep everyone safe, we need to know how fast the storm is moving (speed) as well as what direction it is moving in (velocity). That way people in the path of the storm can make necessary preparations.
500
name the 3 forms of acceleration
