Image with alt text: A grid is shown with a rectangle drawn on it. The rectangle is 8 units long and 6 units wide, labeled with 8 and 6 respectively. Scale: 1 box = 5 feet
Answered by GPT 3.5
To convert the scale drawing from a scale factor of 1 box = 6 inches to a scale factor of 1 box = 12 inches, we need to determine the new length of the boxes in the new drawing.

The given length in the original scale drawing is 10 boxes. As the original scale factor is 1 box = 6 inches, the actual length would be 10 * 6 = 60 inches.

Now, we want to find the length of the boxes in the new drawing, where the scale factor is 1 box = 12 inches. To do this, we need to divide the actual length (60 inches) by the new scale factor (12 inches).

60 inches / 12 inches = 5 boxes

Therefore, the length of the boxes in the new drawing will be 5.

The correct response is:

5

Resistance is measured in units called ohms.
Answered by GPT 3.5
To clarify, resistance is affected by three factors:

1. Length: The longer the material, the higher the resistance.
2. Thickness: Increasing the thickness of a material decreases its resistance.
3. Temperature: An increase in temperature usually increases the resistance of a material.
