When a small stone is dropped into a pond of still water what happens?
When that pebble is dropped in the pond, it pushes water out of the way. The water has nowhere to go but to the side and up, creating a circular peak around the drop point. This peak falls again, under the forces of gravity and surface tension, pushing the water beneath it out of the way.
When a pebble is dropped into a pond of still water what happens Mcq?
1. When a pebble is dropped into a pond of still water, what happens? Explanation: When a pebble is thrown in still water, a circular pattern of alternate crests spread out. The kinetic energy makes the particles to oscillate which comes in contact with it.
What is the most fundamental property of wave Mcq?
The most fundamental property of the wave is frequency because it is the only physical quantity that is independent of the nature of media through which the wave is propagating.
How much energy must a photon have if it is to have the momentum?
How much energy must a photon have if it is to have the momentum of a 10Mev proton? To have the same energy as a 10MeV proton, a photon must have 10MeV… because you just specified the energy of the proton when you said it had 10MeV.
What color is the absence of light?
Black
What 3 colors do the 3 cones respond to the best?
In 1965 came experimental confirmation of a long expected result – there are three types of color-sensitive cones in the retina of the human eye, corresponding roughly to red, green, and blue sensitive detectors.
Is light really white?
Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light.
Is pure white a good wall color?
Sherwin Williams Pure White is one of the best all-purpose shades of white paint for interiors. It’s bright and clean without being stark and cold – a great white for walls, trim and cabinets. Unless you’ve been living under a rock, you’ll know that white is majorly in when it comes to home painting trends.
What is the whitest white from Sherwin Williams?
2. Sherwin Williams Extra White SW 7006. Extra White is said to be Sherwin Williams most WHITE white as it’s a bit cooler looking (I might beg to differ, there’s a different one that wins in my books).
