a truck A moving with a velocity of 30m/s collides with a
stationary trolley B of mass 0.5tonnes after collision the
two bodies were automatically connected.find their common
velocities after collision if the mass of truck is 1.2tonne.
a ball of mass 500g moving with a velocity of 10m/s
collides with another ball of mass 250g.after the
impact,the second ball moved off with a velocity of 8m/s
calculate the final velocity of the first ball.

An ice-box is built of wood 1.75 cm thick, lined with cork
3 cm thick. If in the steady state the temperature of the
inner surface of the cork is 0 ºC and that of the outer
surface of wood is 12 ºC, what is the temperature of the
wood-cork interface? The thermal conductivities of wood and
cork are 0.2 W/m-K and 0.04 W/m-K respectively

I just want to convert the voltage into current i.e.
suppose I have 750V & 1A AC power then I want to convert it
into 12V & 62A DC power only difficulty is that I don't
want to use the tranceformer. Simply to say, I want to make
the step-down without using tranceformer. Please, give me
some ideas.
And also I want the relation between Magnetic Induction &
Weight of the body can be levitated. Or I can say, how much
of magnetic induction requires to lift 500gms weight?
I am heartily thankful to you.
