and can someone please explain how to find the Current if only the resistence and total voltage is given? and I am confused on how to identify when some thing is a series or parallel when both are in a circuit together like this?

is I1 and I3 .22A too because 0.22+0.22+0.22=0.65

i did the question but I am not sure if they are right. i wrote my answers on the attachment

renewable- solar thermal energy,unlimited non-renewable= heat from electric stoves, heater, flames these thermal energies cannot be replenished and are limited resources examples of how it produces energy is through solar thermal, and heating up water that is later turned into electricty. i...

oops i meant as is it an efficent energy? i thinks it effiecent for an energy but I am not sure if I am right

so can i say its both depending on its cirumstance say why? is thermal energy efficient? i googled this question but i kept on getting thermal energy efficiency which is different from what I am asking. can you please help me? my project is due tomorrow!

im not talking about geothermal energy because my teacher gave us topics and mine is thermal energy and i did some research but i still don't get it if its renewable or nonrenewable because i got mixed answers when i researched about it. and are there any advantages for this energy? i think...

This the definition mean the amount of heat energy that you have to put into a substance that will make a change of state but not raise the temperture of it. But I don't know how to apply it to the question

When doing an experiment to find the specific latent heat of fusion of liquid nitrogen, you find that 100 kJ of heat must be removed to freeze 3.8kg of nitrogen at its freezing point. What value will you get for the specific latent heat of fusion of nitrogen? Power=100kj M=3.8kg I don't...

Is it V=sqrt2k/m

But how do I use that to find speed? Is there a formula for that

I know the total mechanical energy for A which is 8820J

some children go tobogganing on an icy hill. They start from rest at the top of the hill as shown in the diagram. The toboggan and children have a combined mass of 90 kg. If friction is small enough to be ignored, determine: The speed of the toboggan at B A is at 10m B is at 0 C is at 3m...

Thanks got it!

At the moment when a shot putter releases a 5.00 kg shot, the shot is 2.00 m above the ground and traveling at 15.0 m/s. It reaches a maximum height of 8.00 m above the ground and then falls to the ground. Assume that air resistance is negligible. a. What was the potential energy of the...
