Why does the coin appear to be nearer the surface of water?
When a coin is placed in water, light rays travel from water to air and get refracted. This refraction makes the coin appear to be nearer the surface of the water than it actually is. This is due to the change in speed of light as it moves from water to air, causing the coin to appear to be at a different position than its actual physical location.
Cones filled with this placed on guests heads at parties?
The cones were filled with perfumed wax.
What is placed inside the balloon that form its shape?
The balloon is filled with a gas.
When a pencil is placed in a glass of water the pencil appears broken at the surface of the water. This is because the light?
bends as it passes from air into water, causing the pencil to appear broken. This phenomenon is known as refraction.
Contact lenses are placed on what surface of the eye?
Contact lenses are placed on the cornea of the eye, which is the transparent front surface covering the pupil and iris.
What is the shape of a drop of oil placed in the surface of water?
A drop of oil placed on the surface of water will typically form a near-perfect circle due to surface tension forces that minimize the surface area of the liquid.
What is the name of cones filled with this placed on guests'heads at parteis?
Party hats or cone hats.
What will happen to a needle place in water?
A needle placed in water will float due to surface tension. The surface tension of water allows the needle to be supported on the surface rather than sink.
A potato cube is placed in a beaker filled with hot salt water and another potato cube is placed in a beaker filled with cold salt water?
The hot saltwater will cause the potato cube to absorb the water due to osmosis, while the cold saltwater will cause the potato cube to release water. The difference in temperature affects the rate of osmosis – higher temperatures increase the rate, while colder temperatures decrease it.
Why does a straw appear to be bent when placed in a glass of water?
When light travels from one medium to another, such as from air to water, it can change direction. This change in direction is called refraction. As light passes through the water and into the air inside the straw, it refracts again, causing the straw to appear bent at the water's surface.
Where should the fulcrum be placed to balance a heavy load?
The fulcrum should be placed closer to the heavy load to balance it. By positioning the fulcrum nearer to the heavy load, more leverage can be generated to lift the load with less effort.
Why does the red crab appear black as it placed very deep in the water?
