Is the normal force equivalent to the weight of an object?

Physics
1 answer:
Greeley [361]3 years ago
4 0

Answer:

No.

Explanation:

If there are no applied forces, normal force is usually equivalent to the weight of the object but if there are outside force (force that makes the object to move) especially if it's inclined, then the inclined force would then affect the normal force.

What do the movements of stars and galaxies tell astronomers about how the universe formed?
natulia [17]
This could be Hubble's law, or something related to it. I think there's a possibly Doppler RED SHIFT in the optical spectra of stars etc as observed on the earth. It seems that they are accelerating away from the earth, and that the further away they are the faster they are moving.
It seems that this has been connected to the idea of "The Big Bang" theory of the origin of the universe which seems to have superceded Professor Sir Fred Hoye's Steady State theory of the universe.
There's some Special Relativity in this lot, too.

Which structures allow for the removal of wastes from the developing fetus?
castortr0y [4]

The fetus relies upon its mother as it develops. These are some of the things it needs:

<span>protection against knock and bumps, and temperature changes oxygen for respiration nutrients (food and water) </span>

The developing fetus also needs its waste substances removing.

The fetus is protected by the uterus and the amniotic fluid, a liquid contained in a bag called the amnion.

what happens to light when it falls upon a material that has a natural frequency equal to the frequency of the light?
mixas84 [53]

The energy from the light is transferred to the material, causing it to vibrate and absorb the light.

What is energy?
In physics, energy is the quantitative quality that is transmitted to the a body or a physical system, and is discernible in the work performed as well as in the form of light and heat. The law of conservation states that although energy can change its form, it cannot be created or destroyed. Energy is indeed a conserved quantity. The International System of Units' (SI's) joule is the measurement unit for energy (J). A moving object's kinetic energy, a solid object's elastic energy, chemical energy caused by chemical reactions, and the potential energy that an object stores (for instance because of its position inside a field) are examples of common forms of energy.

When light falls upon a material that has a natural frequency equal to the frequency of the light, the light will be absorbed by the material. This is due to resonance, which occurs when the frequency of the light matches the natural frequency of the material. The energy from the light is transferred to the material, causing it to vibrate and absorb the light.
