Can you give me the equation of impulse?
We need not calculate magnitude of impulse here, one experiencing larger impulse will rise higher.
i thnk both balls have same impulse dnt u thnk?
impulse roughly can be said as change in momentum. That is a hint.
yeah n p=mv is the realation
If a balls has risen higher, it means it must have greater initial velocity at the bottom ?
Two wires lie in the plane of paper and carry equal current in opposite direction as shown. At a point midway between the wires, the magnetic field is ?
You mean the direction ?
yeah the magnetic field is it out of the paper? its zero into the paper or at the bottom of paper?
You must be knowing right hand thumb rule ?
yeah but i just didnt remember it
isnt it zero?
Nop it isnt
Both will add up,
y? they are in opposite directions they cancel the effect n become zero
if they are in same then they will be added up
or it will be out of the paper?
You got to revise your right hand thumb rule to understand that, for same direction, magnetic fields cancel in between.
it will be zero :)
The coefficient of static friction between car’s tires and a level road is 0.80. If the car is to be stopped in a maximum time of 3.0 s, its maximum speed is (a) 2.4 m/s (b) 23.5 m/s (c) 7.8 m/s (d) 2.6 m/s whch equation will be applied here?
A body moving with uniform acceleration has velocities 20 m s -1 and 30 m s -1 when passing through points A and B. Then wht the velocity mid-way between A and B is ?
. A monkey of mass 20-kg rides on a 40-kg trolley moving with constant speed of 8 ms -1 along a horizontal track. Frictional forces can be neglected. If the monkey jumps vertically with respect to the moving trolley to grab the overhanging branch of a tree, the speed of the trolley after the monkey has jumped off is
