Activity In this activity, you will use Hubble's law, v=Hod, and the definition of velocity, v= $, to calculate the approximate age of
the universe, t. Consult the math review e if you need help with scientific notation, exponents, or solving one-step
equations.
Part A
so that
To find time, the age of the universe, you must first isolate the variablet. Rewrite the velocity equation v=
you are solving for time.

Natural forces that can alter ecosystems include seasons and climate changes. t or f

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?
