Which is the rate at which heat is transferred from one surface to another? The units on the rate of heat transfer are Joule/second, also known as a Watt. This equation is applicable to any situation in which heat is transferred in the same direction across a flat rectangular wall. It applies to conduction through […]

Do you need flux to solder? Yes, you can solder without flux. While it is helpful in the process of soldering as the flux helps break down the oxides on the metal, it is not needed. Also, most solder nowadays come with a rosin core which does the job of flux helping breaking down oxides. […]

How can a flying Aeroplane be in dynamic equilibrium? Spacecraft flight dynamics involve three main forces: propulsive (rocket engine), gravitational, and atmospheric resistance. Propulsive force and atmospheric resistance have significantly less influence over a given spacecraft compared to gravitational forces. What are the 3 axis of rotation in an aircraft? Regardless of the type of […]

How do you calculate pressure in a manometer? Manometers. One of the most important classes of pressure gauges applies the property that pressure due to the weight of a fluid of constant density is given by p = hρg. What is the formula for calculating atmospheric pressure? Atmospheric pressure is the pressure caused by the […]

Can you get in trouble for uploading to Course Hero? Looking at Course Hero notes to get ideas from past students about what they understood from the course and their study/revision notes etc is not misconduct. Uploading your own study notes you have from a course is not misconduct. Is using Course Hero illegal? The […]

How do you figure volume of a cylinder? The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . How do you find volume with diameter […]

Who are construction design teams? The design team involves the professionals that are required to design the works and perhaps to ensure the completed works satisfy the project brief. Who are the members of a construction team? Construction team members have more than one preferred team roles and that the most preferred team role of […]

How do you set a range on a multimeter? You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you’ve measuring a 12V battery, use the 20V setting. What does the range button […]

How is the change in entropy affected by temperature? Affecting Entropy If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases. (4) When a liquid becomes a gas, its entropy increases. What […]

Is it possible for two screw dislocations of same sign to annihilate each other explain your answer? It is possible for two screw dislocations of opposite sign to annihilate one another if their dislocation lines are parallel. What is the difference between the angle of Burgers vector and dislocation line in edge dislocation? Explanation: The […]
