Answer:

Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.

A 0.70-kg disk with a rotational inertia given by MR 2/2 is free to rotate on a fixed horizontal axis suspended from the ceiling

Setler [38]

Answer:

The force will be "9.8 N".

Explanation:

The given values are:

mass,

m = 0.7 kg

M = 2

g = 9.8

Now,

⇒ $\tau = T \alpha$

then,

⇒ $\frac{1}{2}mR^2(\frac{1}{R}\frac{dv}{dt}) =M(g-a_t)R$

⇒ $\frac{1}{2}m \ a_t=m(g-a_t)$

⇒ $a_t=\frac{2g}{(\frac{m}{M} +2)}$

On substituting the values, we get

⇒ $=\frac{2\times 9.8}{\frac{0.7}{2} +2}$

⇒ $=8.34 \ m/s$

hence,

⇒ $T=mg+M(g-a_t)$

On substituting the values, we get

⇒ $=0.7\times 9.8+2(9.8-8.34)$

⇒ $=6.86+2(1.46)$

⇒ $=6.86+2.92$

⇒ $=9.8 \ N$

How are science and technology the same

Ilia_Sergeevich [38]

Answer:

Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science
