When finding between Y and Z, the other two would be in series and in parallel with the 5 Ω one.How to do this? ans is C
Same steel means same Young Modulus. The difference will be in extension.
Momentum before collision: 8+4=12
None. They are just a mixture of properties of solids, liquids and gases.View attachment 54368
I know the answer is C but which states do A B and D represent?
Find the percentage uncertainty in diameter and multiply it by 3 as radius is cubed in the formula of volume. Add the percentage uncertainty in mass.can anyone help me with question no. 6. the answer is D

Thank u sooo much, you are such a big helpFind the percentage uncertainty in diameter and multiply it by 3 as radius is cubed in the formula of volume. Add the percentage uncertainty in mass.
Thank youDensity = Mass/Volume
Volume of sphere = 4/3*pi*r3
Percentage uncertainty of diameter = 0.02/2.20*100 = 0.909%
Percentage uncertainty of mass = 0.005/0.506*100 = 0.988%
Since the diameter has to be halved to find the radius and then cubed, we multiply the uncertainty by 3.
Therefore, 3(0.909) + 0.988 = 3.7%
Could you please explain why?No, it has nothing to do with that. The element with the greatest mass to charge ratio has the lowest speed.

Could you please explain why?
There's a formula for it too.It's simple common sense. Imagine a particle with a large mass but a small charge. It has a bigger inertia, so it would have a lower speed.
Thanks! But even if Q is moving fastest, it's at equilibrium position, so why won't its displacement be zero?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
