Answer:
The current through the tube is 73.39A.
Explanation:
The relationship between the resistivity , the electric field , and the current density is given by
This equation can be solved for to get:
Since the current is
Now, for the tube of mercury , , and the area is ; therefore,
Hence, the current through the mercury tube is 73.39A.
Boyle’s Law states that volume increases with temperature
'C' and 'D' are the same statement, and none of the 3 choices
is good.
Electrical energy is produced in a generator, a solar panel, or
a battery, not in things with resistance.
From the generator or battery, current flows through a circuit of
one or more components.
The greater the resistance of a component, the more energy is
LOST as the current flows through it. The component dissipates
the energy in the form of heat.
The strength of the electric field is 1.035 * 10^7 N/C.
<h3>What is the electric field?</h3>
The term electric field refers to the region in space where the influence of a charge is felt. Now we know that the electric field is obtained form the formula;
E = F/q
E = electric field
F = electric force
q = magnitude of charge
F = 8.8 * 10^-3 * 10 m/s^2 = 0.088 N
q = -8.5 nc or -8.5 * 10^-9 C
E = 0.088 N/ -8.5 * 10^-9 C
E = 1.035 * 10^7 N/C

The answer is; nodes
A standing wave occurs when two waves with the same properties moving in the opposite direction, in the same media, interfere with one another. Nodes are points where the waves interact destructively causing an appearance of the wave standing still. The opposite of nodes is antinodes where they are points of maximum displacement due to constructive destruction.
