Is it better to leave lights on? You should leave the lights on because it takes more energy to turn them back on than you’ll save by turning them off. FALSE! Fluorescent lights do take a small surge of power when turned on, but this is significantly smaller than the amount saved by turning them […]

How do you classify a biome? Biomes. A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome. What are three […]

Is smoke a mixture or solution? Is smoke a element compound or mixture? Smoke is a collection of airborne solid and liquid particulates and gases emitted when a material undergoes combustion, so we can say that smoke is the mixture. What is smoke an example of? Smoke is an example of solid aerosol in which […]

How often should you workout to see results? If you really want to see results reflected on the scale and continue to make progress over time, you need to commit to working out at least four to five days per week. But remember, you’ll build up to this. To start, you might only want to […]

What is an algorithm heuristic give an example? Christophides’ algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look […]

Is a black hole faster than light? Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light. Can we ever travel faster than light? Albert Einstein’s special theory of relativity famously dictates that no known […]

What are 10 examples of biodegradable? Answer Food waste. Paper waste. Human waste. manure. sewage. Sewage sludge. Hospital waste. Slaughterhouse waste. What is the most environmentally friendly bag? Paper bags have some advantages over plastic bags when it comes to sustainability. They are easier to recycle, and, because they are biodegradable, they can be used […]

Why noble gases are chemically inert? Explaining the inertness of noble gases The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions. Is oxygen inert or reactive? Element […]

How many volts does a wind turbine produce? 600V How much electricity does a 1mw wind turbine produce? One MW is equivalent to one million watts. The production of power over time is measured in megawatt-hours (MWh) or kilowatt-hours (kWh) of energy. A kilowatt is one thousand watts. Production of power at the rate of […]

What parts make up a generator? Main components of a generator Engine. Alternator. Fuel System. Voltage Regulator. Cooling and Exhaust Systems. Lubrication System. Battery Charger. Control Panel. Can a motor generate electricity? You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its […]
