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 […]

What are the four principles of sound? Since sound is a wave, it has all of the properties attributed to any wave, and these attributes are the four elements that define any and all sounds. They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration. […]

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 […]

What are the 3 types of thermal energy transfer? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]

What are the 4 types of materials? Materials can be classified into four main groups: metals, polymers, ceramics, and composites. What are the 5 types of inventory? 5 Basic types of inventories are raw materials, work-in-progress, finished goods, packing material, and MRO supplies. Inventories are also classified as merchandise and manufacturing inventory. What is EOQ […]

What happens when a material is deformed Why? When a sufficient load is applied to a metal or other structural material, it will cause the material to change shape. This change in shape is called deformation. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its […]
