The lower and upper fixed points of a
mercury-in-glass thermometer are
marked X and 180mm respectively.
On a particular day the mercury
meniscus in the thermometer rises
to 60mm. If the corresponding
reading on a Celsius scale is 20°C,
what is the value of X?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

What’s #16 asking me and how do i solve it?

Which of the following will cause an induced current in a coil of wire? the constant field of the earth passing through the coil a magnet resting near the coil a magnet being moved into or out of the coil a wire carrying a constant current near the coil
