Why is an electromagnet considered to be a temporary magnet?
An electromagnet acts as a magnet only while electricity is passing through the coil. Once the electricity is turned off, the electromagnet ceases being a magnet. Electromagnets are much used in scrapyards. Attached to a crane, metal is picked up and deposited into railway wagons, or road haulage vehicles, to be sent for recycling.
A 8000 kg engine pulls a train of 5 wagons each of 2000 kg along a horizontal track if the engine exerts a force of 40000N and the track offers friction force of 5000N then calculate 1 the net acclera?
Ans. :- net acceleration = 40000 - 5000 = 35000 N.
What do you mean by Pendulum principle of transport?
Transportation costs are divided between two producing regions when mutually necessary for the supply of goods. That rule of transport is known as the pendulum principle. The significance of this policy is immense in the expansion of the iron and steel industry in the Lakes region of America. Rail wagons and ships never travel empty, as they travel from the Mesabi and adjoining Panch Lake areas to the Appalachian region with iron ore and to the lake area with coal from Appalachian. It is divided into the coal-producing industries of the Bay Appalachian and the locust-producing industries of the region. The iron and steel industry in Pittsburgh, Youngstone etc. benefited economically as a result of this pendulum policy.
What is the speed if electric current?
Three speeds can be distinguished here. 1. The random speed of individual electrons (whether there is a current or not) is about 1/5 the speed of light. Not entirely sure about this one; it would also depend on the temperature. 2. The systematic movement of electrons when there is a current (i.e., more electrons move in one direction than in the other) is extremely slow; usually a fraction of a millimeter per second. 3. The speed of the current itself is typically about 2/3 the speed that light has in a vacuum, or about 200,000 km/sec. Note that this is NOT the speed of individual electrons; rather, energy is transferred from one electron to the next. This IS the speed at which a signal can be propagated, for example in a network cable.

Why were the cattle trails so important and what impact did they have on Texas?
Before the arrival of the railway and modern road transport, cattle had to be driven from where they were reared to distant markets to be sold. Cattle drives could take several weeks. Once the railway arrived, the cattle would be driven to the nearest railhead and loaded onto cattle wagons - a much safer and speedier affair. So though the cattle trails were important, the coming of the railroad was even more important.
What is a wagonload?
A wagonload is an amount that can be loaded onto a wagon, the individual load of a single wagon, or a type of freight train service in which individual wagons have separate destinations.
