What has more water lakes or rivers? By comparison, freshwater comprises only 3% of the earth’s water, and surface water is only 0.3% of that 3%. Furthermore, rivers and lakes comprise 2% and 87%, respectively, of surface water. Thus, rivers contain only 0.00018% and lakes only 0.0078% of the earth’s water. Who has the most […]
How long does it take to settle a rear end collision?
How long does it take to settle a rear end collision? After reaching a settlement agreement, you might be wondering how long it will take until you receive your compensation. For cases with minor crashes and minor damages, cases typically take 30 to 90 days. If your case goes to court, it could take years […]
What is meant by Vsepr theory?
What is meant by Vsepr theory? The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. Repulsion between these pairs of electrons can be minimized by arranging them so that they point in opposite directions. Why is Vsepr […]
Why is the voltmeter connected in parallel with a resistor when measuring its voltage?
Why is the voltmeter connected in parallel with a resistor when measuring its voltage? A voltmeter is an instrument that measures the difference in electrical potential between two points in an electric circuit. In order for a voltmeter to measure a device’s voltage, it must be connected in parallel to that device. This is necessary […]
Which is used as the dielectric layer in MOS capacitor?
Which is used as the dielectric layer in MOS capacitor? An MOS capacitor is made of a semiconductor body or substrate, an insulator and a metal electrode called a gate. Practically the metal is a heavily doped n+ poly-silicon layer which behaves as a metal layer. The dielectric material used between the capacitor plates is […]
What is the formula of starch?
What is the formula of starch? The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form. What is the structure and function of starch? Starch is the form […]
What is the formula for calculating core area?
What is the formula for calculating core area? The equation you will need to use is: A = L x W. This answer will be in millimeters squared, and effective core area is always reported in millimeters squared (mm^2), so you have no factor conversion to make here. How do you find the cross sectional […]
How do we measure the depth of the sea?
How do we measure the depth of the sea? The depth of the ocean is calculated by knowing how fast sound travels in the water (approximately 1,500 meters per second). This method of seafloor mapping is called echosounding. Echosounders can use different frequencies of sound to find out different things about the ocean. What’s the […]
What will happen if we lose mangroves?
What will happen if we lose mangroves? Research shows that mangroves play a key role in carbon sequestration – removing about 1,000 tonnes of carbon per hectare – over thousands of years. The loss of mangroves contributes to nearly one-fifth of global emissions from deforestation. Climate change also affects their survival. How many mangroves are […]
