Why is it called a watt? The watt is named after James Watt, an 18th-century Scottish inventor., The watt (symbol: W) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. […]

Is Diamond a luminous object? A diamond isn’t luminous object. It doesn’t have light of it’s own. Although it is a great thing to reflect the light that falls on it. That purity is what allows the diamond to show the dispersion of light and that’s the beauty. Is Earth a luminous body? It is […]

Does the right side of the brain control? Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving. What is the newest drug for bipolar disorder? 18, 2015 (HealthDay News) — A new antipsychotic drug […]

Can you manipulate more than one variable? The short answer to whether scientists can use more than one manipulated variable in their experiments is “yes.” But just as important as the answer to this question is understanding why scientists would want to include two manipulated variables. How many control variables can you have? Similar to […]

What do you do if you hit black ice? Deal with a black ice encounter. If you do hit black ice, your first reaction must be to remain calm and avoid overreacting. The general rule is to do as little as possible and allow the car to pass over the ice. Do not hit the […]

What is the lifespan of a neutron star? 1 million years Can you touch a neutron star? So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star. And if it collects enough mass it would collapse […]

How are metamorphic rocks classified? Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. The other minerals have been crushed and deformed into a fine-grained matrix (Mtx). What are metamorphic […]

What is an example of a isolated system? A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. An isolated system does not exchange energy or matter with its surroundings. Is an isolated system? In physical science, an isolated system is either […]

Does higher volume mean higher density? Density is determined by an object’s mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density. It is about how heavy something is compared to the same amount (volume) of water. Are volume and mass […]

What is the ratio of molecules in 1 mole? 1 mole of any compound is the Avogadro’s number, 6.023×1023 . And, 1 mole of HNO3 = 6.023×1023 molecules. Now, both compounds have the same number of molecules. The ratio of molecules between both the compounds is 1:1 . Which is the correct formula to calculate […]
