Answer:
B. Spring balance - a device used for measuring the weight or force of gravity acting on an object.
Explanation:
A Force is any interaction that changes the motion or position of an obkpjectbthatbit is interacting with. Whenever there is an interaction between two objects, there is a force exerted by each of the objects on one themselves.
Forces are generally divided into contact forces and non-contact over field forces.
In contact forces, the two objects physically in contact with each other. Examples of contact forces are push or pull forces, frictional forces, tensional forces, spring forces, etc.
Non-contact forces are forces in which the two objects interacting do no need to be physically in contact with one another. Examples include, gravitational forces, magnetic forces, electrical forces, etc.
Instruments used in measuring forces are known as force gauges.
From the instruments listed above:
A. A ruler is an instrument used in measuring length
B. Spring balance is a device used for measuring the weight or force of gravity acting on an object.
C. A thermometer is an instrument used in measuring temperature
D. A windbvane is an instrument used in measuring wind direction.

Answer:
Natural selection is a process in which organisms are fit to adapt and live in the environment. Natural selection was an idea developed by Charles Darwin, Darwin contributed this idea when he was studying birds and tortoises at the Galapagos Islands. He then wrote his famous book, <em><u>O</u></em><em><u>r</u></em><em><u>i</u></em><em><u>g</u></em><em><u>i</u></em><em><u>n</u></em><em><u> </u></em><em><u>o</u></em><em><u>f</u></em><em><u> </u></em><em><u>S</u></em><em><u>p</u></em><em><u>e</u></em><em><u>c</u></em><em><u>i</u></em><em><u>e</u></em><em><u>s</u></em><em><u>.</u></em> Evolution is also very similar, evolution is a process in which organisms reproduce and mutate in order to survive and adapt. As you can see, natural selection and evolution are alike in many ways.

Well thats because things changed in science. Newtons law of gravity (which was all things that come up must come down) evolved once scientist figured out that in space things float around. Science always evolves weather it's in a year or a day, but if your asking about HOW it evolved, thats something different. Hope I'm helping you!
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties.
