To bring something to a stop the same force that was applied to speed it up can be used to stop it. If a greater force is used it will stop quicker.
To find the answer for this question, you simply need to divide 20 by 8, which is the speed he is traveling.
20 / 8 = 2.5
The football player will run 20 yards in 2 1/2 seconds.
Hope that helped! =)
It makes calculations with very large and small numbers easier.
Scientific notation is a system used in order to It makes calculations with very large and small numbers easier. It is useful as it allows very large number that would take a lot of space to write otherwise, and it allows them to be calculated easier. for example is a incredible large number, but written in this form is immediately understandable and useful for calculation.
true
Explanation:
this is because melting point and boiling point decreases down the group because they are held together by attractions between positive nuclei and delocalised electrons
The correct answer is
C. The battery
The battery is a device that provides a potential difference in the circuit, and so an electromotive force (e.m.f.) which pushes the electrons in the circuit from the negative pole towards the positive pole of the battery, so they move through the circuit. Therefore, it provides electrical energy.
