Q.26
Q8,9,13,18,26 Please help me
Im kindof lousy at explaining dis 1Q13 ?
Projectile me aisa sab ata hain ?Im kindof lousy at explaining dis 1
Initial E = E(x) + E
Final E = E(x) only
So Final E = (1/2) Initial E
I thought it was answered by Zep.. something Copycat [/quote]Q.26
When charge Q is at position of q. It exerts a force of da electric field strength on da charge n its magnitute depends upon da strength of da electric field n da amount of charge on Q.
F = Eq
E = F/q
lol i wanted 2 write ( y ) instead ofProjectile me aisa sab ata hain ?
Wat [/quote]I thought it was answered by Zep.. something Copycat
Acha... sorry [/quote]dude Zepudee is da 1 whos asking da questions -_-
I deleted da old post cuz i qouted my own post by mistake[/quote]Acha... sorry
Q.9
Impulse (or change in momentum) = Force * time
Impulse = 60 * 0.5 = 30 Ns
Initial momentum of trolley = 30 kg * 3 m/s= 90 Ns
Impule (or change in mometum) = 30 Ns
So final momentum = 90 - 30 = 60 Ns
Final speed = final momentum/mass
Im kindof lousy at explaining dis 1
Initial E = E[x] + E[y]
Final E = E[x] only
So Final E = (1/2) Initial E
ur most welkum. btw i did find da speed, check out my post
Q.18
Pressure = F/A = W/A = mg/A = g * m/A
m/A = Pressure/g
Density = m/V = m/A * 1/h
Density * h = m/A
Denisty * h = Pressure/g
Denisty = (Pressure/g) /h
Density = Pressure/(g * h)
Density = 15 200/(10 * .8)
Density = 15 200/8
Density = 1900 kg/m³
Answer: B
yes ofcourse. dat wuz a crappy explanation anyway.Sorry Hadi, but can you please explain a bit more about this?
Volume = length * width * heightHadi Murtaza Oh ya, why Density=m/A*1/h? Heh heh
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.
