How will the image appear if an object is held extremely close to a concave mirror?

If an object is held extremely close to a concave mirror, the image will appear magnified, upside down, and virtual. The image will be located beyond the focal point of the mirror.


Who do words look different when you hold them up to a mirror?

Words appear different when held up to a mirror because the mirror reflects images as a mirror image, causing the text to appear backwards. This occurs because the mirror reverses the direction of the light that bounces off the text before it reaches our eyes.


Why is the leaf held at a right angle to the light source?

The leaf is held at a right angle to the light source to maximize the surface area exposed to sunlight for photosynthesis. This position ensures that the chloroplasts in the leaf receive optimal light energy for the process of photosynthesis to occur efficiently.


How did the revolutions of the motor compare when the solar cell was held to an incandescent light source vs the sun as a light source?

The revolutions of the motor were likely lower when the solar cell was held to an incandescent light source compared to the sun as a light source. This is because incandescent light sources emit less intensity and different spectrum compared to sunlight, resulting in reduced power generation by the solar cell and, in turn, fewer revolutions of the motor.


What color best attract heat and why?

Heat as radiation is best attracted to and held by dark colors, because they have low reflectivity. Stand in the sun on a hot summer day with a black shirt on, then with a white shirt on - the difference is immediately apparent.
