Homework Statement
I don't understand voltage and electrical energy. So Voltage is power/unit of current. also V=RI. In power lines, the power losses are minimised by using large amounts of voltage. From P=VI, I gets smaller. But ohms law says current will increase. HUH?
Power loss = RI^2...
Ahh it's good to know that there are students here that are at my level. It's pretty awsome that there are people who are highly experienced in one or more areas contributing in this forum.
I honestly don't see how this knowledge(or more like understanding) is going to benefit you.
From all I know...Integration is the process of finding areas, volumes etc under curves. The fundamental theorem of calculus is able to use the primitive of the curve to find the area under the curve...
I'm still doing school maths, but I can see how complex numbers can be used to represent force vectors if you know what I mean. So I guess it really useful in physics
Hey Bill K. Isn't the mass increase seen from an another reference point will only be apparent? The person inside the spacecraft will not notice any mass change.
im so confused lol
Can someone please clear this up for me?
Lets say the distance of Point A from Earth is 10.4 light years. Some spacecraft is traveling 0.95c.
So. The person in the spacecraft will see Earth contract but Earth will see the spacecraft contract in length too. The thing I'm confused on is...
