A rock weighing 98 newtons is pushed off the edge of a bridge 50 meters above the ground What was the potential energy of the rock before it began to fall?

Kinetic Energy = 1/2 x Mass x Velocity2
As the velocity while the rock is on the bridge's edge is 0, it does not have any kinetic energy:
Therefore the answer is zero.

Can bungee jumping have gravitational potential energy and how?
Yes, potential energy is an energy something has because of its position in a gravitation field. Thus the jumper standing on the bridge before the jump has gravitational potential energy. When the jumper jumps the gravitational potential energy is converted into kinetic energy (the energy something has because of it motion) an is also stored in the rubber band as elastic strain energy. When the energy stored in the rubber band exceeds the kinetic energy the jumper halts and bounces back and the energy in the rubber is re converted into potential energy. The jumper oscillates on the rubber rope until the energy loss due to friction and wind resistance uses up the potential energy present in the system at the start of the jump and the jumper hangs still from the rope.

A truck weighing 300000N crosses a bridge When it reaches the centre the support forces on the left and right sides of the bridge are each 400000 What is the weight of the bridge alone?
500000N or 500000/9.81= 50968 Kg
What was the name of the bridge before the confederation bridge?
Before the Confederatration Bridge was built it was a ferry, so the bridge had no prior name. The locals call the bridge the "fixed link"

What is weighing bridge?
A weighing bridge is usually a large, flat, rectangular metal plate, set at road level, on which a lorry can be parked to get the lorry's weight. An empty lorry may be weighed on entering a business premises (tare weight) and then weighed when loaded before leaving to give the gross weight. The difference between the gross and the tare will give the net weight of the load put on the lorry. It will also ensure that the lorry is not overloaded, which is a road-traffic offence.
What was used before the Golden Gate Bridge was built?
Before the Golden Gate bridge was built they had to use a Ferry to get across the river(the glolden gate strait)

What is the principle of Carey foster's bridge?
the principle of wheatstone bridge is,there is a potential fall is directly proportional to the length of the wire, and this fall is also equalt to the fall accross the resistances applied in parallel to the battery. It is a form of wheatstone bridge.
