How do you solve word problems? A proven step-by-step method for solving word problems is actually quite simple. Read the problem out loud to yourself. Draw a Picture. Think “What do I need to find?” List what is given. Find the key words. Solve. Check your work. Is there a Photomath for word problems? Photomath […]

What type of bond would form between CL and C? Each atom in HCl requires one more electron to form an inert gas electron configuration. Chlorine has a higher electronegativity than hydrogen, but the chlorine atom’s attraction for electrons is not sufficient to remove an electron from hydrogen….Polar Covalent Bonds. Structural Unit1 Bond Moments (D) […]

What is importance of nucleus? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm. What is Nucleus explain? […]

What is the difference between batteries in series and batteries in parallel? In a series connection, batteries of like voltage and amp-hour capacity are connected to increase the voltage of the overall assembly. In a parallel connection, batteries of like voltages and capacities are connected to increase the capacity of the overall assembly. Why are […]

Is it hard to hit a homerun off a tee? Yes. Any major league player who can hit home runs can hit a ball over the fence off a tee. If he can do it on his size-appropriate field, a major leaguer could EASILY do it. Easily. Does hitting off a tee help? As unexciting […]

How many km can be driven in a day? You should not drive for more than 9 hours a day, excluding breaks. For every 4.5 hours driving you should take breaks amounting to 45 minutes. For long-distance driving, this means you can drive around 500 miles safely in a day. Are long drives bad for […]

Which is an empirical formula? An Empirical formula is the chemical formula of a compound that gives the proportions (ratios) of the elements present in the compound but not the actual numbers or arrangement of atoms. This would be the lowest whole number ratio of the elements in the compound. What is the empirical formula […]

How do you prove two vectors are perpendicular? Remember that two vectors a and b are perpendicular to each other if their dot product is zero. Here in your case , say a = (i + 2 j + 4 k ) and b = (2i – j ) then it is easy to see […]

How many watts is a 1HP motor? 746 watts How fast is a 212 Predator engine? This engine is a performer right out of the box, and should get your go kart running anywhere from 20 mph all the way up to 35mph in its stock form. How many cc is a 15 hp engine? […]

What is the role of the mantle in plate tectonics? The Earth’s mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Because subducted plates are relatively cool, they decrease the temperature of nearby mantle, leaving relatively warm mantle in the regions between […]
