Q 12 & 25 please?

12)
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
initial momentum is (m)(-2v) + (3m)(v) as they;re travelling in opposite directions. total initial momentum = 3mv-2mv = mv
after collision, both stick hence the masses added, momentum after collision = (4m)(V)
initial = final
mv = 4mV
V = mv/4m both the *m* cancelled out, so V = v/4

25)
f=500Hz V=340m/s
V=f λ
so, lambda comes 0.68m
one wavelength means 360 ⁰ i.e, 2π
unitary method,
0.68 : 2π
0.17 : X
so, X = π/2

Check your statement of entry.

PM and AM hi likha hain......... time nai likha :/

 

[Jelleh Belleh]

PM and AM hi likha hain......... time nai likha :/

Is this your first paper you're giving during AM timing?

 

[Thought blocker]

yup...

 

[Jelleh Belleh]

yup...

All my AM exams were at 8:30, I don't know if it's different for other timezones, but definitely get to your centre by 8. Or earliest time possible, in order to avoid any risks.
