Si: A + B = C – D es una ecuación física donde A, B, C y D son magnitudes físicas entonces [ A ] = [ B ] = [ C ] = [ D ]

Answer:

[A] = [B] = [C] = [D] por el Principio de Homogeneidad Dimensional y el uso de operaciones de adición y sustracción.

Explanation:

Por el Principio de Homogeneidad Dimensional, A, B, C y D deben tener las mismas magnitudes físicas para la realización de operaciones de adición y sustracción. Es decir:

[A] + [B] = [C] - [D], donde [A] = [B] = [C] = [D]

A wire carries a current of 10 amps in a direction of 90 degrees with respect to the direction of an external magnetic field of
Oksi-84 [34.3K]

Answer:

15 N

Explanation:

The magnetic force on a piece of current-carrying wire is given by:

F=ILB sin \theta

where

I is the current in the wire

L is the length of the piece of wire

B is the magnetic field strength

\theta is the angle between the direction of B and I

In this problem:

I = 10 A

B = 0.3 T

L = 5 m

\theta=90^{\circ}

Substituting into the equation, we find

F=(10 A)(0.3 T)(5 m) sin 90^{\circ}=15 N

What is the meaning of the word solar in the article "Fire Up the Sun"?
SpyIntel [72]

Answer:

B) Caused by the Sun

Explanation:

If you look at a picture of a solar system, you will see the sun in the middle. The sun is the powerhouse of the solar system. So that means that the sun is the biggest star and can provide enough light to reach earth and keep it lit.

Is it possible for a system to have negative potential energy? a) No, because this would have no physical meaning.b) Yes, as lon
boyakko [2]

Answer: c) Yes, since the choice of the zero of potential energy is arbitrary.

Explanation:

Potential energy depends on the frame in which you are looking at the system.

For example, the potential energy of a lifted object can be written as:

U = mgh

where m is the mass, g is the gravitational acceleration and h is the height of the object.

But the height depends on where we have the zero if the zero is in the ground, then and h = 5m, then the potential energy is positive, but the 0 is the ground of a cliff, and the object is falling down the cliff, then we will have a negative value for h, which implies that we have negative potential energy.

This means that if we want to make the potential energy equal to zero, we must apply kinetic energy to the object (for example, grabbing it and throwing it upwards). On the other hand, if the potential energy is positive, this means that the object will "produce" kinetic energy as the potential energy starts to decrease. For example, an object that is dropped from a three (with an initial kinetic energy of zero) and only potential energy, and as the object falls to the ground the potential energy goes to zero and transforms completely in kinetic energy.
