the electric conductivity of gold is very high
The car has a 12 mile head start, going 80 mph, so his distance is:dcar=80∗t+12
The is going at 108 mph, so his distance is:dcop=108t
Setting them equal to each other we get:80t+12=108t⇒12=28t⇒t=1228=37
So 3/7 of an hour.about 25.7 mins.
The crust. The crust dude! Have you seen the layers of the earth?
There are four states of matter: solid, liquid, gas and plasma. Solid has a shape and volume of its own. A liquid takes the shape of the container does not occupy entirely the volume of the container. For gas, it takes the shape of the container as well as taking the volume of the container. In this case, if the system is only composed of gas, the statement given is true.
