You can visualize the process if you think about a trip in your car. if you tell a friend that you are 140 miles away from your starting point and traveled at 70 miles per hour, your friend would know you had been traveling 2 hours. you know this from the relationship: distance (d) - velocity (v) * time (t) d=v. t or t=d/ (eq. 3) question 12. we can now determine when the universe "started its trip." use the distance and velocity of one of the galaxies and eq 3. finally, convert your answer to billions of years (show your work and conversion, with units). confirm that this answer is roughly in range of your answer to question 5.18 pts age (seconds) = age (years) = billion yrs

this one:

as we gain mass the force of gravity on us increases.

pls mark me as the ! : d

iron would move it is magnetic there is a mag field around the current in the wire

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
