Why would black and ground wires test good on volt meter but black and white wires barely test at all and not work.?

The white wire is loosely connected or not connected somewhere between where you are testing and the source. The first place I would look is a loose screw on the white conductor in the panel.

Why does a light turn when you place black to black and white to ground wire?
You don't say "turn off" or turn on". Light should be connected black to black and white to white and ground to ground. If you connect white to ground it will work, but you are then using the ground wire for an unintended purpose. Neutral is bonded to Ground at the panel. Current on ground wire could cause ground loops and may cause GFCI to trip if you have them in your house.
Should the black wire be bonded to the ground?
It depends on the color coding standards for what country you are in. In the US, the answer is no. The Neutral (white wire) is grounded at the service entrance to the building. The black wire should have roughly the same voltage to the neutral and to the ground. Something to be aware of: If you are using a meter and checking for continuity between the black wire and ground, it may tell you that they have continuity if the breaker is on.
Can you connect a 3 wire 120 Volt with ground to a 2 wire House wire has black and white and ground Appliance has black red white and ground?
To answer this question fully the type of appliance has to be stated and its voltage.

How do you install a swag kit with two wires to a light with three wires?
I am guessing that your 3 wires are black (hot), white (neutral) and bare or green wire (ground). Connect black to black, white to white and ground wire to the metal case of swag kit.

Single Phase 240 120 Volts AC a test meter placed across black wire and Ground wire will read what?
Answer for USA, Canada and countries running a 60 Hertz supply service.A test meter across black and ground in a 120/240 split phase system should read about 120 volts. Note, however, that ground is not the correct reference point; neutral is the correct reference point, and the meter should be connected across black and white, or red and white, or red and black. This is because the ground connection is a protective earth ground, not intended to carry current. Since ground and neutral are tied together at the distribution panel, you might expect them to have no potential difference, but impedance in the conductors will result in a voltage drop across neutral, biasing the voltage seen between hot and ground, as opposed to hot and neutral.

Is it normal to measure 70volts from black to bare ground and 40volts from white to bare ground at an outlet?
No, the white should be approximately zero and the black approximately 110-120, assuming the "bare ground" refers to a bare conductor attached to electrical ground.

What kind of Hornet has a black and white striped tail that lives in the ground?
The bald-faced hornet is a black and white hornet that you can find hovering close to the ground. These hornets are common across the United States.

How do you wire a wire to a wire?
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
There are only 3 phases that come into house main fuse box so where does ground and neutral come from?
It is very rare to have three-phase electricity coming into a residence. One of the wires is probably the neutral (It will be white or black with white stripes.) The ground comes in from a ground rod near the main, and connects to the ground coming from the meter, AND (If the main fuse box is the first disconnecting means,) the neutral and ground bars have to be bonded together in the box.
