My worldview is someone who doesn't exist. Someone who isn't real but i want them to BE real. It's not possible to have someone who is alike you. Who is there for yo when you need them
There all diffrent speeds
You just said that the EMF across the circuit is 7V. So the voltage is 7 volts.
Potential Energy (PE) is found using the equation <em></em><em>mgh</em>, where
m = mass,
g = force of gravity,
h = height
Since we are using the metric system, our force due to gravity will be 9.8m/s^2. Plug in what we know, and we get
(1200kg)(45m)(9.8m/s^2)=PE
Multiply those three variables together, and you will get your potential energy, in Joules! Good luck!
