cool, another one please
the power in the resistor can be calculated by P=(I2)*R → 1.51899A*3.4Ω = 5.16456W
ok its 130.749 mWh
Here:Tom was looking at the image of newsprint using a concave lens by holding it close to the page of the newspaper. The actual height of the words on the newspaper is 3.0 mm.

The vertical drop takes time ...t = 2.12√(l/g)Which, is greater than for the circular path.
