Does heat affect electricity? Temperature affects how electricity flows through an electrical circuit by changing the speed at which the electrons travel. This is due to an increase in resistance of the circuit that results from an increase in temperature. Likewise, resistance is decreased with decreasing temperatures. How can you heat your home without electricity? […]

Is the control group the independent variable?
Is the control group the independent variable? The independent variable is “controlled” or held constant in the control group. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an […]
What is the efficiency ratio formula?
What is the efficiency ratio formula? Definition of efficiency ratio The efficiency ratio is calculated by dividing the bank’s noninterest expenses by their net income. Banks strive for lower e fficiency ratios since a lower e fficiency ratio indicates that the bank is earning more than it is spending. What is the formula for productivity? […]
What is one effect of the uneven heating of Earth caused by the sun?
What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]
What happens to the stopping distance if velocity of a car is doubled?
What happens to the stopping distance if velocity of a car is doubled? When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four. This piece of information will be important for determining your total stopping distance. What […]
