How did Bernard Palissy discover the water cycle? Palissy was the first person to consider the water cycle. When he observed some coastal areas, he found out it had salt water and fresh water. He presumed the fresh water was coming from the rainfall. How did we discover the water cycle? The Earth’s water cycle […]
Do 2 of the same elements make a compound?
Do 2 of the same elements make a compound? A compound is a unique substance that forms when two or more elements combine chemically. A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds. Types of compounds include covalent and ionic […]
Why are clouds flat on bottom and fluffy on top?
Why are clouds flat on bottom and fluffy on top? As warm air rises, the water vapour remains invisible until the air cools enough for it to condense into water droplets. Providing that more air feeds in from below, new cloud will form there and preserve the flat bottom. The existing cloud is pushed upwards, […]
Can you hack radio frequency?
Can you hack radio frequency? In fact, some hackers are even capable of using radio signals to hack into an unconnected device and steal confidential corporate data. Researchers in Israel have developed a technology that extracts information from a machine using radio frequencies and wireless communications. What are the basics of radio? Radio waves are […]

What is Laplace nebular theory?
What is Laplace nebular theory? Nebular Hypothesis, an explanation of how the solar system was formed, proposed by Pierre Simon de Laplace in 1796. Laplace said that the material from which the solar system was formed was once a slowly rotating cloud, or nebula, of extremely hot gas. The most serious concerns the speed of […]
What is a maximum load moment?
What is a maximum load moment? Load Handling And Composition On A Forklift – Part III: Maximum Load Moment. The pivot point on a sit-down counterbalanced forklift is the axle of the front wheels. It is this Load Moment that determines how much overturning force is being applied to the forklift (Load moment = Weight […]
Which type of copper wire plain or insulated is used in designing an electro magnet?
Which type of copper wire plain or insulated is used in designing an electro magnet? Answer. The copper wire used in an electromagnet is insulated with a coating of nonconductive insulation like plastic or enamel in order to prevent the current from passing between the wire turns. The windings of the wire multiply the effect […]
