Is water soluble in water? Liquids are miscible or immiscible… So, water does not dissolve in water. What are 2 things that would not dissolve in water? Many substances will not dissolve in water, including oil, paraffin wax and sand. What can water not dissolve? Sugar, sodium chloride, and hydrophilic proteins are all substances that […]
Which Colour has lowest frequency?
Which Colour has lowest frequency? red Is red light hotter than blue light? Red light has a longer wavelength than blue light; this means, blue light has a higher frequency than red light. Since there is more energy in higher frequencies, theoretically, blue light is warmer than red light. Since there is more energy in […]
Can a DC motor run on AC?
Can a DC motor run on AC? The AC series motor you describe is a universal motor, and will work fine on DC. The speed characteristics will be a little different, since when running on AC there’s a significant reactive drop in the field windings that reduces the available driving emf. Can you charge DC […]
What is forward bias?
What is forward bias? Forward biasing means putting a voltage across a diode that allows current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction. Why is the base emitter junction forward biased? Forward bias on the emitter to base junction causes the electrons to flow from […]
What is the rule for adding and subtracting sig figs?
What is the rule for adding and subtracting sig figs? When you add or subtract, you assign significant figures in the answer based on the number of decimal places in each original measurement. When you multiply or divide, you assign significant figures in the answer based on the smallest number of significant figures from your […]
How husbands miss their wives?
How husbands miss their wives? Improving your relationship with your husband is the best way to make him genuinely miss you. You can start by considering his point of view instead of focusing only on your own. It’s human nature to think about our own individual needs, but good husbands and wives also think about […]

Sometime around 12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming. Where did first farmers come from? Farming is thought to have originated […]
Where is rich in ozone?
Where is rich in ozone? Most ozone (about 90%) is found in the stratosphere, a region that begins about 10-16 kilo- meters (6-10 miles) above Earth’s surface and extends up to about 50 kilometers (31 miles) altitude (see Figure Q1- 2). Where is skin the thickest? Epidermis varies in thickness throughout the body depending mainly […]
What increases resistance in a wire?
What increases resistance in a wire? Resistance increases with the temperature of the wire. The hotter wire has a larger resistance because of increased vibration of the atomic lattice. When a material gets hotter the atoms in the lattice vibrate more. What’s the relation between current and resistance? The relationship between current, voltage and resistance […]
What element has 40 protons and 53 neutrons?
What element has 40 protons and 53 neutrons? Zirconium – Element information, properties and uses | Periodic Table. What if there were no electrons? You would become plasma as there are no electrons to form molecules. You wouldn’t exist unless you were plasma. Meaning you would die. Nothing other than plasma would exist in such […]
