What does the plot show about the relationship between the two variables? Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation . If the data points make a straight line going from the origin out to high x- and y-values, then the variables are […]

How much does concrete expand in hot weather?
How much does concrete expand in hot weather? An average value for the coefficient of thermal expansion of concrete is about 10 millionths per degree Celsius (10×10-6/C), although values ranging from 7 to 12 millionths per degree Celsius have been observed. Does concrete absorb water? Yes, concrete can absorb water because it’s porous like a […]
What can I use instead of flux to solder?
What can I use instead of flux to solder? Here’s this Soldering Flux Alternative You Must Check Out! Petroleum jelly is one of the best flux alternatives you can use. Many people have found that petroleum jelly works just as well as commercial flux. The truth is that you don’t have to use commercial flux, […]
In which entropy is maximum?
In which entropy is maximum? The principle of maximum entropy states that the probability distribution which best represents the current state of knowledge about a system is the one with largest entropy, in the context of precisely stated prior data (such as a proposition that expresses testable information). Can entropy be infinity? Since no finite […]
What is the role of commutator in electric motor?
What is the role of commutator in electric motor? The commutator assures that the current from the generator always flows in one direction. On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil […]
Why acceleration is zero at mean position in SHM?
Why acceleration is zero at mean position in SHM? Acceleration is zero because at that point, it is the mean position, which means it is the equilibrium position. Hence, the spring is not compressed (or extended) or the pendulum suffers no tangential force. It is not that velocity is maximum, that’s why the acceleration is […]
Which quantity is constant?
Which quantity is constant? A constant-quantity is a constant value of some physical-quantity, like 3 meters or 55 miles per hour. Constant quantities are distinguished from function-quantities, which map some quantities to other quantities. Which physical quantity is constant everywhere? The physical quantity which remains constant in uniform circular motion is Speed. Uniform circular motion […]
What landforms are created by glacial erosion and deposition?
What landforms are created by glacial erosion and deposition? Glaciers cause erosion by plucking and abrasion. Valley glaciers form several unique features through erosion, including cirques, arêtes, and horns. Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers. What are three landforms created by glaciers that have […]
What are the factors affecting kinetic energy?
What are the factors affecting kinetic energy? 1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy. What is expression of kinetic energy? The kinetic energy of a body is […]
