An object is situated to the left of a lens. A ray of light from the object is close to and parallel to the principal axis of th

e lens. The ray passes through the lens. Which one of the following statements is true?
The ray passes through a focal point of the lens only if the lens is a converging lens.

The ray passes through the lens without changing direction, no matter whether the lens is converging or diverging.

The ray crosses the principal axis at a distance from the lens equal to twice the focal length, no matter whether the lens is converging or diverging.

The ray passes through a focal point of the lens only if the lens is a diverging lens.

The ray passes through a focal point of the lens, no matter whether the lens is converging or diverging.

Answer:

The ray passes through a focal point of the lens only if the lens is a converging lens.

Explanation:

By the principles of geometric optics, we know that all rays parallel to the principal axis of converging lens, change its direction to a point situated in the axis of the lens. This last point is know as the focal point.

Hence, the only truth choice is:

The ray passes through a focal point of the lens only if the lens is a converging lens.

I attached an image to illustrate this situation

Kim’s experiment showed that chicken eggshells were stronger when she gave the hen feed, to which extra calcium had been added.
astraxan [27]

The step of this scientific method is "draw conclusion".

<h3>What is scientific method?</h3>

The scientific method is the process of objectively establishing facts through testing and experimentation.

The basic scientific process or scientific method involves the following;

  • making an observation
  • forming a hypothesis
  • making a prediction
  • conducting an experiment
  • analyzing the results and
  • drawing conclusion.

Thus, if Kim’s experiment showed that chicken eggshells were stronger when she gave the hen feed, to which extra calcium had been added. The step of this scientific method is "draw conclusion".

A charged object traveling 7 m in a uniform electric field of 5 N/C experiences a 4 J increase in Kinetic Energy.
Travka [436]

To solve this problem it is necessary to apply the principles of conservation of Energy in order to obtain the final work done.

The electric field in terms of the Force can be expressed as

E = \frac{F}{q} \rightarrow F=Eq

Where,

F = Force

E= Electric Field

q = Charge

Puesto que el trabajo realizado es equivalente al cambio en la energía cinetica entonces tenemos que

KE = W

KE = F*d

In the First Case,

4 = (qE)d\\q = \frac{4}{Ed}\\q = \frac{4}{5*7}\\q = 0.1142C

In Second Case,

KE = q E'd

KE = (0.1142)(40)(7)

KE = 31.976J

The total energy change would be subject to,

\Delta KE = 31.976-4

\Delta KE = 27.976J

Therefore the Kinetic Energy change of the charged object is 27.976J
