Answer:
D: When one bulb burns out, all the other lights stay on
Explanation:
In series combination of light bulbs same current must flow through all the bulbs and hence if one bulb is burn out then current through all bulbs tripped to zero and all bulbs will turn off.
Now in parallel combination all bulbs are connected parallel to the source of energy due to which the bulbs will remain in circuit if any one bulb is burn out.
So here if we used combined circuit of the bulbs i.e. parallel then in that case if one of the bulb is burn out then it must show that rest of the other bulbs must glow.
so here correct answer would be
D: When one bulb burns out, all the other lights stay on

Organs are made up of different types of organs.
Answer:
F = 20 N
Explanation:
It is given that,
The fulcrum is 1 m from the left end, and 3 m from the right end. A block of 60 N is hung to the left end. We need to find the force needed on the right end such that it balances it. The torque acting on the left end is equal to the torque acting on another side. Let F is the force needed on the right end. So,
So, the force of 20 N is needed on the right end.
This is quite an opinonated question because everyone learns and retains information differently. For me personally, I learn best in physics by doing lots and lots and LOTS of practice problems. the more repetition you get with the material the easier it will be for you to tackle problems quickly. The repetitive practice will also stick the equations in your head for a very long time. Hope this helped! I wish you the best of luck on your exam!
