TRUEFriction is the reason more force is needed to push an object across a rough surface.

The modern periodic table arranges elements based on properties. These properties include valence electrons of the elements and density for example.

forms that can be read by computers are now used to eliminate human error when evaluating and calculating data.

Abstract classes are to be extended until to a concrete class.

Can have both abstract & non abstract methods.

An Abstract class can not be instantiated.

A non abstract class can be extended to an abstract class.

If At least one abstract method present in a class then that class must be abstract.

abstract & final modifiers can never be together.

abstract classes can have both abstract methods & non abstract methods.

Mathematical Figures Are Universal &&;nd Can Be Understood By Other Scientists

making measurments

a stratified random sample

Thay collect data with a graph

experimentation or observation

:)

measurements should be made precisely to ensure accuracy (:

For one particular study, yes. But it is not possible for all data collection across the whole world for all purposes.

measurements used in data collection involve the use of mathematics

Resistance from air.

Yes, definitely. Not by the computer, but by the information/data/numbers typed in by a human using the keyboard.

Measurement is involved.
