a. m/s
b. m/s2
c. m2/s
d. kg-m/s2
Answer: Momentum is mass times velocity (P = m*v)
Explanation: Momentum is defined as the "amount of movement"
The momentum of an object moving can be calculated as:
P = m*v
where P is momentum
m is the mass of the object
v is the velocity of the object.
Notice that momentum has a given direction (the same of the velocity) so it is a vector.
b. blue, yellow, and white are primary colors.
c. they are complementary colors of light.
d. they are both primary colors of light.
Answer: The correct answer is c.
Explanation: According the RGB color model, the light of the two complementary colors will combine to form a white light. This happens because the complementary colors combine at full intensity.
Complementary colors according to RBG color model is:
From the above information, we conclude that blue light and yellow light are complementary colors of light and hence, the combination of two will produce white light.
Answer:D) Gamma rays
Explanation:
Energy of a photon= h( Planck constant) * f (frequency)
So we take a look at the electromagnetic spectrum i am attaching and see which wave will have the highest frequency.
As a note frequency is inversely proportional to wavelength so highest energy is also shortest wavelength.
Therefore the highest energy are gamma rays
Hope this helps
Among the options provided, gamma rays from a star radio produce the highest energy photons. This is due to the larger energy differences in gamma rays. The radiation emitted by a microwave oven, a heat lamp, local station waves, or a doctor's X-ray are of lesser energy comparatively.
The source that produces the highest energy photons among the options provided is 'gamma rays from a star radio'. This is because gamma rays are part of the electromagnetic spectrum and known for having short wavelengths and high energy. In fact, the energy of gamma rays is much larger than the energy released by a microwave oven, a heat lamp, radio waves from a local station or even a doctor's X-ray machine.
Nuclear energy shells in gamma rays have energy differences that are millions of times larger than electromagnetic radiation from electronic transitions. In contrast, examples like a microwave oven work with much smaller energy scales, producing electromagnetic radiation that is absorbed by water molecules, leading to an increase in the molecules' rotational energies.
Microwaves and heat lamps emit infrared radiation, doctors use X-rays, and local stations emit radio waves. However, none of these have as much energy as gamma rays, which can be produced in stars, among other places. Gamma rays are the most energetic form of light and are created by the hottest and most energetic objects in the universe, such as stars and black holes.
