three_resistors_are_arranged_in_a_circuit_as_shown_above1559105724.PNG image

Three resistors are arranged in a circuit as shown above. The battery has an unknown but constant emf ε and a negligible internal resistance.

Now, determine the equivalent resistance of the three resistors.

A) 12 Ω B) 10 Ω
C) 16 Ω D) 15 Ω
 
Answer & Explanation Answer: A) 12 Ω

Explanation:

From the given circuit,

three_resistors_are_arranged_in_a_circuit_as_shown_above1559105964.PNG image

The resistors R1 and R2 are in parallel connection and R3 is in series with R1 & R2

The equivalent resistance of R1 and R2 is

Req = (12 × 4)/(12 + 4) = 3 Ω.

Adding R3 in series with the pair gives

R = Req + 9

R = 3 + 9

R = 12 Ω.

Q:

In Germany the Mittle Land Canal runs from the 

A) Elbe to the Wesser B) Rhine to the Wesser
C) Order to the Elbe D) Rhine to the Order
 
Answer & Explanation Answer: D) Rhine to the Order

Explanation:

In Germany an important system of canals has been built in the low lying land between the Baltic Heights and the mountains in the southern part of the country. The Channels cut by these Ice-age rivers and later abandoned, have made it comparatively easy to join up the present river by canals which assist considerably in the movement of heavy goods in the north German Plain

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

It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us."

Is that going to be a great day, or what?

All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German. As complex as all this sounds, it could turn out to be relatively simple.

What will be possible in the future?

A) Personalised DNA chips for people to assess their own inherited predispositions B) You are at great risk for heart disease
C) You will not be able to determine what food you should eat D) You will be unable to adjust your diet
 
Answer & Explanation Answer: A) Personalised DNA chips for people to assess their own inherited predispositions
