What is difference between igneous and sedimentary rocks?

What is difference between igneous and sedimentary rocks? There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. What are the […]

What does a negative angular acceleration indicate to you?

What does a negative angular acceleration indicate to you? Negative angular velocity(ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration(α) is a “push” in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Is clockwise positive or […]

How much forest is cut down for agriculture?

How much forest is cut down for agriculture? Rainforests across the world are in great danger. Food and Agriculture Organization’s 2016 State of the Forests report revealed that 7 million hectares of forest are lost annually while agricultural land expands by 6 million. Does agriculture affect rainforest? Agricultural use of some rainforest land proves to […]

Does plasma have an indefinite shape?

Does plasma have an indefinite shape? Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. Which state of matter has a high density and […]

Fungus, plural fungi, any of about 144,000 known species of organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike […]

What is the formula for calculating efficiency?

What is the formula for calculating efficiency? The formula to calculate work efficiency is the ratio of output to input expressed as a percentage. The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. How do you calculate the maximum […]

Does higher entropy mean more stable?

Does higher entropy mean more stable? A system which is more disordered in space will tend to have more disorder in the way the energy is arranged as well. The entropy has increased in terms of the more random distribution of the energy. In essence . . . “a system becomes more stable when its […]

What is diode resistant?

What is diode resistant? Hence, diode resistance can be defined as the effective opposition offered by the diode to the flow of current through it. Ideally speaking, a diode is expected to offer zero resistance when forward biased and infinite resistance when reverse biased. What is the reverse resistance of a diode? Reverse resistance is […]
