BUT HOW WILL IT GLOW IF S1 IS NOT CONNECTED??

Ans 3:

Class : Class 8
But it will still remain as an open circuit... there may not be continuous flow of electricity 🤷‍♀️

Ans 4:

Class : Class 7
but s1 is closed so then the current can come to x too. no?

Ans 5:

Class : Class 8
Bulb Y will still continue to glow if both the switches are open because bulb Y is directly connected to the battery and both of its terminals are connected to the battery. The answer to the given question is option b.

Ans 6:

Class : Class 6
The answer is (B) because there are no switches in the ire that are being connected to bulb Y. Hence, bulb Y can glow but bulb X can't because S1 is not closed.

The answer should be A. I understand what you are saying but look they told that the planets C and D are gases. They did not asked how big they are but they asked are they made up of gases. So the answer should be A since C is the largest.

Ans 2:

Class : Class 8

Ans 3:

Class : Class 5
'c' is jupiter which is the biggest the answer is 'd' . Saturn is the second biggest planet . if they were asking about the biggest heavenly body in our solar system then options 'a' and 'd' would have been correct as the sun is the biggest heavenly body in our solar system and Jupiter is second

Class : Class 5
Planet D is Uranus which is mostly rocky and icy. I do not understand why it is not A and D. someone please clarify.

Ans 6:

Class : Class 6

Ans 7:

Class : Class 5
The planet c is Jupiter the Largest and in a option it is given 2nd largest so it is incorrect but in c option it is written that a and b are made up rocks and it is also incorrect . So the answer should be a and c both .please update the question

Ans 8:

Class : Class 5
Sorry for the misconception , the answer is d

Ans 9:

Class : Class 8
You're right!!!!!LAVANYA...

Ans 10:

Class : Class 4
I didn't understand that d is Uranus and it's called the ice giant then why option d is saying that c and d are made up of gases. as per my understanding two options are incorrect, A and D.
