Hogden is conducting an experiment to determine how much force it takes for a nail to puncture a tire, causing a flat. He uses f

ive identical nails and tests them on five identical tires filled with equal amounts of air. He hits each nail one time, applying a different force each time. His results are recorded below. Trial Force (lbs) Result nail 1 15.0 no flat nail 2 30.0 no flat nail 3 45.0 no flat nail 4 60.0 flat nail 5 75.0 flat What can Hogden conclude from his results? A. It takes exactly 60.0 pounds of force on the nail to cause a flat. B. It takes exactly 45.0 pounds of force on the nail to cause a flat. C. It takes between 60.0 and 75.0 pounds of force on the nail to cause a flat. D. It takes between 45.0 and 60.0 pounds of force on the nail to cause a flat.

A long corridor has a single light bulb and two doors with light switch at each door.
Zigmanuir [339]

Answer:

The answer is below

Explanation:

Let A represent the first switch, B represent the second switch and C represent the bulb. Also, let 0 mean  turned off and 1 mean turned on. Since when both switches are  in the same position, the light is off. This can be represented by the following truth table:

A                    B                       C (output)

0                    0                        0

0                    1                          1

1                     0                         1

1                     1                          0

The logic circuit can be represented by:

C = A'B + AB'

The output (bulb) is on if the switches are at different positions; if the switches are at the same position, the output (bulb) is off. This is an XOR gate. The gate is represented in the diagram attached below.
