Answer:
![\boxed {\boxed {\sf 120 \ Joules}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20120%20%5C%20Joules%7D%7D)
Explanation:
Work is equal to the product of force and distance.
![W=F*d](https://tex.z-dn.net/?f=W%3DF%2Ad)
The force is 8 Newtons and the distance is 15 meters.
![F= 8 \ N \\d= 15 \ m](https://tex.z-dn.net/?f=F%3D%208%20%5C%20N%20%5C%5Cd%3D%2015%20%5C%20m)
Substitute the values into the formula.
![W= 8 \ N * 15 \ m](https://tex.z-dn.net/?f=W%3D%208%20%5C%20N%20%2A%2015%20%5C%20m)
Multiply.
![W= 120 \ N*m](https://tex.z-dn.net/?f=W%3D%20120%20%5C%20N%2Am)
- 1 Newton meter is equal to 1 Joule
- Our answer of 120 N*m equals 120 J
![W= 120 \ J](https://tex.z-dn.net/?f=W%3D%20120%20%5C%20J)
The work done is <u>120 Joules</u>
True, scientists often talk to each other to figure out if their results were similar and what they could have done better.
Although, talking to other scientists does have risks, other scientists could copy your work and further better it.
So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol
Answer:
The electromagnetic force
Explanation:
The electromagnetic force is one of the four fundamental forces of nature. Namely, they are:
- Electromagnetic force: it is the force exerted between electrically charged particles (and between magnetic fields). The force can be either attractive (if the two charges have opposite signs) or repulsive (if the two charges have same sign), and it acts over an infinite range.
- Gravitational force: it is the force exerted between objects with mass. It is always attractive, and it also has an infinite range of action. It is the weakest of the four fundamental forces.
- Strong nuclear force: it is the force that acts between protons and neutrons inside the nucleus, and it is responsible for keeping the nucleus together and preventing it from breaking apart (due to the electrostatic repulsion between protons)
- Weak nuclear force: it is the force responsible for certains nuclear decays, such as the beta decay, in which a neutron turns into a proton, emitting an electron and an antineutrino.
