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 […]
What are the 4 types of materials?
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?
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 […]
Which is an empirical formula?
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?
How many watts is a 1HP motor?
What is the role of the mantle in plate tectonics?
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?
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 has the least density?
What has the least density? The first chemical element with the lowest density is Hydrogen and the highest density is Osmium. What is the lightest strongest metal? Magnesium Which metal is less dense water? lithium, sodium and potassium are less dense than water so they float on the surface of the water. the metals move […]
What is the difference between an active and a passive wheel speed sensor?
What is the difference between an active and a passive wheel speed sensor? Passive sensors are larger and less accurate than active sensors and only start to operate when the wheel reaches a certain speed, therefore they have limited operation at lower speed. Active sensors require an external power source to operate and work in […]
