Why do ceramics have a high melting point? Ceramic Materials have high heat capacity and have both ionic and covalent bonds. The ability of a material to absorb heat from its surrounding isits heat capacity. Since ionic bonds are strong and unidirectional the melting point of ceramics is higher. What are the properties of ceramics? […]

How do you control shrinkage in injection Moulding? By changing temperatures, pressures, and packing and cooling times, it is possible to mitigate shrinkage. By applying pressure to a liquid plastic, the molecules can be compressed into a smaller volume which enables more material to be injected into the mould to compensate for shrinkage. How do […]

What process do engineers use to solve problems? Engineers will often use reverse-engineering to solve problems. For example, by taking things apart to determine an issue, finding a solution and then putting the object back together again. Engineers know how things work, and so they constantly analyse things and discover how they work. How can […]

How do you calculate output speed? Calculating Output Speed Using Pulley Diameters and Input Speed RPM Output/RPM Input = Multiplication Factor. On a belt-driven fan the two primary speeds required are the RPM of the Motor and the RPM of the fan. Formula. RPM Input/RPM Output = Diameter Out/Diameter In. Formula. RPM Input/RPM Output = […]

Which research misconduct most likely occurred? Which type of research misconduct most likely occurred if someone intentionally removes data points from the data set in order to generate a deceptive conclusion? This situation most likely involves falsification. Falsification includes deceptively changing or omitting data. What is the most appropriate process for research collaborators to use? […]

How do flight times work with time zones? Airline departure and arrival times are always given in terms of the local time zone – that is, the time zone at the airport in question for each segment of the trip. So if you’re flying from the West Coast of the United States to the East […]

How many times the human heart beats in a minute class 10? Answer. On an average, a human heart beats for approximately 8- time in a single minute. If we talk about the total heartbeat rate in a day then it will be equivalent to 115000 times that will be equal to a total of […]

What happens when you increase the temperature of a thermistor? When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse. What are thermistors made of? Thermistors are made from semiconductor materials, typically metallic oxides, using cobalt, manganese, or nickel. The temperature–resistance relationship in […]

How do you make clay bricks stronger? Mud Bricks If the amount of sticky clay is more, then bricks will develop cracks during drying. Similarly if sand is more, then bricks will become weak. Mud raw bricks are dried slowly in a shade. To make raw mud bricks stronger, grass is mixed in soil and […]

What fluids are called Newtonian? Water, air, alcohol, glycerol, and thin motor oil are all examples of Newtonian fluids over the range of shear stresses and shear rates encountered in everyday life. Single-phase fluids made up of small molecules are generally (although not exclusively) Newtonian. Are all fluids non-Newtonian? In reality most fluids are non-Newtonian, […]
