Answer:

A ray coming from the object parallel to the principle axis after reflection from the mirror would pass through focus or refracting through the lens would converge or appear to diverge from focus.
An incident ray passing through the focus would reflect/refract parallel to the principle axis.
A ray passing through the pole of the lens would transmit through it.

A ray which is incident at an angle to the mirror or lens would reflect or refract respectively and the angle of reflection or refraction would follow the laws of reflection or Snell's law of refraction respectively.

The important point is in image tracing:

1) The rays travelling from very far, meet at focus after interaction with the lens/mirror.
2) The rays travelling through focus are parallel to the principal axis.
3) The object must be kept facing the front part of the mirror.

The capacitors in each circuit are fully charged before the switch is closed. Rank, from longest to shortest, the length of time

8_murik_8 [283]

The concept used in this is circuit analysis using the simplification of resistors and capacitors.

Explanation:

The time constant for each of the circuits in figure A, B, C, D and E. Therefore, rank the length of time the bulbs stay lit from longest to shortest by using the value of time constant for each circuit. The rank of the time constant of the circuit is C > A = E > B > DC > A = E > B > D.

Capacitance is the central concept in electrostatics and constructed devices called capacitors are essential elements of electronic circuits.

If more charge is placed on the conductor the voltage increases proportionately. The ratio of the charge to the voltage is called the capacitance C of the conductor C= q/v.

The resistance increases if you add resistors in series and decreases if you add them in parallel. on the other hand the capacitors increases if it is added parallel and decreases if added in series. hence the circuit longest time constant takes longest time to discharge.

To compare the hearing capacities of 5 of his friends, Ravi designs a simple experiment. He places a CD player at the end of a l

aliya0001 [1]

Answer:

A) having each person listen to just 1 song instead of 5.

Explanation:

Ravi could accurately use the outcome to compare the hearing capacities of his friends by this experiment if appropriate precautions are observed.

Playing 5 well known songs simultaneously could result to the interference of sounds when each participant moves away from the player. Which could naturally cause the variation in volume of the songs played with respect to the increasing distance.

Therefore, the reliability of the result from this experiment can be increased if each person listen to just 1 song instead of 5 at a predetermined volume. Each participant would be able to focus on hearing a song during the experiment.

A hot piece of iron is thrown into the ocean and its temperature eventually stabilizes. Which of the following statements concer

777dan777 [17]

Answer:

E. The ocean gains more entropy than the iron loses.

Explanation:

When there is a spontaneous process , entropy of the system increases . Here hot iron is losing entropy and ocean is gaining entropy . Net effect will be gain of entropy . That means entropy gained by ocean is more than entropy lost by iron .

Hence option E is correct .
