In a Daniell cell, the depolarizer, positive and negative electrodes are respectively

A bread toaster uses a current of 4A when plugged in a 240 volts line it takes 1 minute to toast slices of bread. What is the energy consumed by the toaster?

Two forces whose resultant is 100N are at right angles to each other. If one of them makes an angle of 30° with the resultant, find the magnitude of the other force.

A body of weight WN rests on a smooth plane inclined at an angle 6' to the horizontal. The component of the weight down the slope is

Two identical freight cars roll without friction (one at 1 m/s, the other at 2 m/s) toward one another on a level track. They collide, couple together, and roll away in the direction that

Two 5000-kg freight cars roll without friction (one at 1 m/s, the other at 2m/s) toward one another on a level' track. They collide, couple, and roll away together with a combined momentum of

Two identical freight cars roll without friction towards each other on a level track. One rolls at 2m/s and the other rolls at 1 m/s. After the cars collide, they couple and roll together with a Speed of

Two 5000-kg freight cars roll without friction (one at 1m/s, the other at 2m/s) toward each other on a level track. Thus one car's kinetic energy is 2500 J and the other's is 10,000J Before they collide their total kinetic energy is

Two 5000kg freight cars roll toward each other (one at 1m/s, the other at 2m/s) on a level track Thus before they collide one car's kinetic energy, is 2500 J and the other’s is 10,000 J. After they collide (and couple together) their total kinetic energy is

Two 5000-kg freight cars roll toward one another, (one at 1 m/s and the other at 2m/s) on a level track. Thus before they collide, one car's kinetic energy is 2500 J and the other's is 10,000 J. They collide and couple together. The kinetic energy turned into heat (mostly warming the couplers) in the collision is....

A 1-kg ball dropped from a height of 2m rebounds only 1.5 m after hitting the ground. The amount of energy converted to heat is about

A sandbag in outer space moves at 3m/s and collides and sticks to a half-as-massive sandbag initially at rest. Compared to the kinetic energy of the moving bag before collision, the kinetic energy of the coupled bags after collision is
