It is reasonable because the ripples in the rock show how old and how fast the water went to make the rock. It also describes the time that it has been there, depending on how many years ago it was.
( I tried. I'm not that great at any kind of science )
Sometimes, you can play sport for a longer time than you should. You should always stop and take a little break and always drink water. Also, if something starts to hurt, stop, let someone responsible know and take a break.
Answer:
11.625 Ohm
Explanation:
Let V be the Voltage charge of the loop, as this is constant we know that before the resistor addition the current I is:
V/R1 = 1.9 or V = 1.9R1
After the resistor addition to series R = R1 + 3.1
I = V/R = V/(R1 + 3.1) = 1.5
We can substitute V = 1.9R1
1.9R1 = 1.5R1 + 1.5*3.1
0.4R1 = 4.65
R1 = 4.65/0.4 = 11.625 Ohm
Answer:
Only electrons
Explanation:
When a current flows through a metal wire, the moving charges are electrons since electric current is the flow of electric charge in an electric circuit. This electric charge are therefore electrons.
