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 happens if a torch is shone at 90 degrees under water. would it refract?
If the torch light is fully underwater it could be held at any angle between 180 degrees before it refracted, as refraction involves light passing between two media with different densities. If water is constantly the same density it will not bend the light.
What color does gold leaf appear when held up to the light?
When held up to the light, gold leaf appears as a shiny, metallic gold color.
Can you think of creating a shape that would give a circular shadow if held in one way and a rectangular shadow if held in another way?
Yes, a shape that could achieve this is a cylinder with a circular base. When held upright, it would cast a circular shadow, and when laid flat, it would cast a rectangular shadow due to the shape's profile and orientation relative to the light source.
Why must a magnifying glass be held so that light from the sun forms a small circular dot?
A magnifying glass needs to be held so that the light from the sun forms a small circular dot because this concentrates the sun's rays in a small area, increasing the intensity of the light and heat. This focused light is what allows the magnifying glass to create enough heat to ignite objects like paper or dry leaves.

How is a tagged stamp noticed when collecting?
The simplest way is to expose the stamp to various wavelengths of ultraviolet light. They stamps will glow. Often the tagging can be seen with the eyes if the stamp is held at an angle to the light.
How much light passes through two polarizing filters held at right angels to each other?
None
What job was held by most workers in the united states at the founding of the country?
farm worker source- got it right on a quiz (By Solomon Zelman)
Is flashlights a common noun?
Yes, "flashlights" is a common noun. It is a general term used to refer to a portable hand-held electric light source.
How do you remove the license place light assembly on a 2005 mustang?
If you look under were the plate is the light is held in by 2 plastic screws just get a flathead screwdriver and separate them and light assembly will come right out
What is a Dutch angle?
A Dutch Angle is when a camera shot is take while the camera is held at an angle. Rather than vertical lines appearing in parallel to the edges of the picture, they appear at an angle.
What does torch mean?
A torch is a stick or stick-like structure, which is on fire at the top, and held at the bottom, that is used either as a source of light, or to set fire to other things.
If two polaroid filters are held with their polarization axes at right angles to each other the amount of light transmitted compared to when their axes are parallel is?
When two polaroid filters are held with their polarization axes at right angles to each other, no light is transmitted as the filters block all light waves aligned with their polarization axes. When their axes are parallel, the maximum amount of light is transmitted because all light waves can pass through without being blocked.
Who is pictured in the watermark which you can see to the right of Lincoln when you look at a series 1999 US 5 bill held up to the light?
Uh, Lincoln
What is an angle grinder?
