ratio will be P1^2xM2/p^2xM1.... but as by law of conservation of momentum … initial momentum=0.. so p1=-p2.....hence final and the correct answer is M2/M1...

As per my knowledge there is no need of taking 30 degree but if it earth should rotate 17 times faster then that of all other planets then body lying on equator become weightless ....that`s it
yes it will have constant kinetic energy because the mass m is moving with angular velocity omega in a circular path as we know k.e. in circular path is 1/2*I*omega 2 therefore k.e. remins constant
@ yusuf below i am explaining the recoil velocity of the gun derivation , suppose m1 is the mass of the bullet m2 = mass of the gun . v1 = velocity of the bullet v2 = velocity of recoil of gun before ...
let m be the mass for 1 m length chain then 25 cm length the mass would be: = > m/4 balacncing the forces we get, f = mg/4. u*(3m/4)*g = mg/4 u= 1/3
The answer of this easy question is A or B or C or D as the gun fire a certain speed which is constant and the acceleration acting downward
The answer for above question shall be ------------------------------------------------------------------------------ Sqrt (2h/g)
dear student or sir a small mistake occured in your typing. velocity is considered in m/s and acceleration is considered in m/s^2. so I solve velocity in this question given conditions in the...
ANS: 2m/s 2 equate the torque I alpha = force * r (r = radius of wheel) 0.1*a/r = 2*10* r ( a = accelaration) therefore a=2m/s 2 ( r = 0.1m)
let total distance be x meter b/w A and B. them to mid – point the eqns. are: (x/2) = 7*t1 + 0.5at1^2..............(1) and v = 7 + a*t1 For M to B (x/2) = (a*t1 + 7)*t2 + 0.5*a*t2^2...............(2) ...
As the pocess is isothermal chanege in Internal energy would be zero and hence temperature remains costant that is T. From ideal gas eqn. PV =nRT 1.5 * 2.5*1000 = 2000/32 * 0.0821 * T we get T =...
Work Done in Polytropic process = > xRT/(1 – n) = > (1000/32) * 0.0821 * 300/(1 – 1.3) = > -2565.625 Joule. From Q = U + W U = mC(T2 – T1) as Temp. is constant. U = 0. Hence Q = W = – 2565.25 Joule.
The component of the vector A along B geometrically is: Bcos(theta) = (A.B/|B|).(Bcap) = 5/(2)½ (i + j) option is correct.
Yes, beacuse when resultant force is perpendicular to the velocity then, the Power that is: dot product of force and velocity would be zero. as the angle is 90 degree. Hence with zero Power there...
Hi Gaurang, I use the Android app, HashLearn, to get my doubts cleared by IIT tutors on HashLearn. You should definitely try it. :)

The loops are closed therfore, The total work done by each loop would be zero. Hence it is a closed loop. The net Work Done is zero for closed loop as change in Volume is zero being volume constant.
at 3 seconds , h = 60*3 – 0.5g*9 = > 135 meter. P.E. = mgh = >1350m K.E = 0.5m*3600 = > 1800m % = 1350m/1800m * 100 => 75%
I THINK QUESTION IS INCOMPLETE plz check and cend again 1/2 c theta^2, WHAT IS THIS KINDLY SEND AGAIN ASAP I AM WAITING TO HELP U
plz send the image . then i will better understand & then i will try to help u. i am waiting for figure given in the question. if u dont know how to attach or send figure then ask me.
