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.

Earth orbits around the Sun at an average speed of 30 km/s. How far does the Earth move in a year (3.16 x 107 s) as it revolves
maks197457 [2]

Answer:

d=v*t=(30\frac{km}{s})(3.16x10^{7})=9.48x10^{8}km

Explanation:

Our knowable variables are <em><u>velocity and time</u></em>

v=30 \frac{km}{s}

t=3.16x10^{7}s

We know that v=\frac{d}{t}

<em><u>So, with the data that we have we can </u></em><em><u>calculate distance</u></em>

d=v*t=(30\frac{km}{s})(3.16x10^{7})=9.48x10^{8}km

Someone, please help!! cant understand
ch4aika [34]

Answer:

4400 N

Explanation: (c)

P= \frac{F}{A}

F= PA

P= pressure

A= area

P=800x10^{3\\ and A= 5.5 x 10^{-3}m^{2}

Force F= 800x10^{3}x0.0055= 4400 N

force exerted by the gas on the piston is 4400 N
