How are the two variables associated with each other? Association between two variables means the values of one variable relate in some way to the values of the other. Association is usually measured by correlation for two continuous variables and by cross tabulation and a Chi-square test for two categorical variables. What can be used […]
What type circuit connection should a light bulb be connected to maintain maximum brightness?
What type circuit connection should a light bulb be connected to maintain maximum brightness? Answer. Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go […]
What will happen if you dip blue litmus paper to a lemon juice?
What will happen if you dip blue litmus paper to a lemon juice? If you dip blue litmus paper into lemon juice, it turns red. Because lemon juice is acidic, it makes blue litmus paper turn red. Because soapy water is alkaline, it turns red litmus paper blue. And pH represents the acidity or alkalinity […]
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 […]
Where is surface area used in real life?
What is difference between balanced and unbalanced force?
What is difference between balanced and unbalanced force? If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of […]

What is difference matter and substance?
What is difference matter and substance? Answer. anything which occupies space and has mass is called matter. But the that has specific composition and chemical characteristics is substance. What is the substance of matter? substance: A form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom […]
Does heat affect electricity?
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? […]
Which two factors are needed to calculate the velocity of an object?
Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Speed, the […]
