What kind of datatype is being input for number1 number2 number3? The datatype for number1, number2 and number3 it will be integer and even the output will be integer. the programmer will decide whether to convert integer to float or not. What is the line continuation symbol used in python to tell the interpreter that […]

What is the coefficient of X? A number used to multiply a variable. Example: 6z means 6 times z, and “z” is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: x is really 1x. Sometimes a letter stands in for the number. What is the coefficient […]

What is vertical position in welding? A “vertical weld” is defined as a weld that is applied to a vertical surface or one that is inclined 45 degrees or less (fig. 7-35). Welding on a vertical surface is much more difficult than welding in the flat or horizontal position due to the force of gravity. […]

What are the requirements for heat transfer to occur? Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower […]

How do you calculate gravitational potential energy? Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh. How do you find height with potential energy and mass? The formula for potential energy depends on the force acting on the two objects. For […]

How do you calculate the shear force of a beam? The shear stress at any given point y1 along the height of the cross section is calculated by: where Ic = b·h3/12 is the centroidal moment of inertia of the cross section. The maximum shear stress occurs at the neutral axis of the beam and […]

What is encryption techniques? Encryption is the method by which information is converted into secret code that hides the information’s true meaning. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers. What is encryption used […]

What is the equation of the line with an X intercept of and ay intercept of 1? Since the x-intercept is -2, the point (-2,0) lies on the graph of the line. Since the y-intercept is 1, the point (0,1) also lies on the line. Therefore, the slope, m, is equal to (1-0) / (0-(-2)) […]

What is the difference between 4-20mA and 0 10V? Thank you for this question! 4-20mA is better for noise resistance (provided you run it properly in a shielded cable grounded at one end). 0-10V is better for troubleshooting. To troubleshoot a current loop, you have to have a multimeter capable for reading DC current in […]

What is the probability that a card randomly drawn from a standard deck of 52 cards is not a king? 4852 What is the probability of drawing a black card or a face card? A card that is a black face card is drawn. There are 6 black face cards, so the probability is 6/52 […]
