Q:

Brightness of bulb depends on voltage or current?

A) Current B) Voltage
C) Both A & B D) None
 
Answer & Explanation Answer: C) Both A & B

Explanation:

Brightness of bulb depends on both voltage and current. The brightness depends on power.

Since we know that  Power (P) = Voltage x Current = V I

So whether you increase the current or the voltage the brightness will increase.

 

Example Illustration:

 If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance).

 

Hence, the brightness of a bulb depends on power i.e, both voltage and current.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Everyone expected Mary Zophres to win for her retro-revival Technicolor clothes in La La Land — the eventual winner, Colleen Atwood for Fantastic Beasts and Where to Find Them, seemed surprised too. But as other awards began to slip away from the well-reviewed musical, a theme could be teased out. What is Fantastic Beasts if not a plea for equal treatment of people, magical or otherwise? Then, Arrival, a film about the inherent benignity of aliens (read immigrants) won for Best Sound Editing. Hacksaw Ridge, which is, in a way, an anti-guns movie, won in two categories. Fences, about an African-American father who fears racial discrimination, took home the Oscar for Best Supporting Actress. Earlier, Moonlight, featuring two minority communities (black and gay), won for Best Supporting Actor. This turned out to be one of those years the Oscar voter was underestimated. As a majority of voters are actors, there was the tendency to think they'd reward La La Land, a celebration of creation: the heroine wants to make movies, the hero wants to make jazz. It looked like the year of The Artist all over again.

 

What does the lead female actor in La La Land want to do?

A) Make jazz B) Make movies
C) Make music D) Make magic
 
Answer & Explanation Answer: B) Make movies

Which of the following statements is/are correct?

1.In June 2016, the LIGO group of scientists announced the detection of a second set of gravitational waves.

2.Gravitational waves were generated due to merger of two black holes at about 1.4 billion light-years distant.

3.Gravitational waves were inserted due to collision of two white dwarf stars at about 1.4 billion light-years distant.

Select the correct answer using the code given below.

 

A) 1 only B) 1 and 2 only
C) 2 and 3 only D) 1, 2 and 3
 
Answer & Explanation Answer: D) 1, 2 and 3

Explanation:

All are correct. Gravitational waves don’t get distorted or altered by interactions with matter as they go through space. gravitational waves have pure information about the objects and events that created them. The Government of India has given approval for the world’s third advanced Laser Interferometer Gravitational Wave Observatory (LIGO-India) to set up in India.
