light
100
what is the path of electricity?
substation-transformer-junction box-outlet-lamp
100
what falls faster with no friction? - basket ball - golf ball - same rate
same rate
100
what is the chemical equation for sugar salt water carbon dioxide
salt-Naci sugar-C6Hi2O6 water-h2o carbon dioxide-co2
100
what type of light can penetrate your skin
gamma rays or x rays
200
what happens if a electrical circuit is not complete?
the power is not going to be deliverd
200
give two examples of forces
-opening a door -hitting a base ball
200
how do you find acceleration
acceleration=final speed- initial speed divided by time examples of acceleration= -slowing down -speeding up -changing directon
200
what is a chemical change
a change in matter that produces one or more new substances is a chemical change. ex: burning paper
200
how would solar panels affect your power grid
it would increase
300
what happens if the circuit is complete
it will turn on
300
what is the first newton law
an object at rest and an object in motion will stay unless acted by an unbalanced force (basically inertia)
300
what would happen to the line on a speed vs time graph if the object traveling stops suddenly?
its going to drop suddenly
300
what is a physical change?
any change that alters the form or appearance of a substance but dosent make the substances into another substance ex: ice-water-vaper or rip paper
300
what is visible light, infrared light, and ultraviolet light?
visible- they are the only waves we can see they are the rain bow red- long purple- short infrared- longer than visible light, more energy, and we cant see but we feel the heat ultraviolet- they are slightly shorter than violet light and carry large amounts of energy
400
what conducts electricity
-copper -metal
400
what is th 2 and 3 newton law
2- force=mass times acceleration 3- for every action there is an equal and opposite reaction
400
what are gamma rays
they are produced by radio activity and they have a short wave length and a high frequency and carry large amounts of energy
500
what is a transformer on a pole
it lowers the voltage
500
what is inertia
an object will stay at rest and an object will stay moving un less acted upon an unbalanced force
