Answer:

C-) Compound machines are made from two or more simple machines

Explanation:

Simple machines use the principle of Lever, where a force multiplied by a distance is used. That is why a simple machine does not produce electricity. Simple machines must be composed of at least two parts. For this reason the combination of simple machines results in a compound machine.

Batteries are made of two metals with different electron affinities. What does the phrase “electron affinity” mean and how does
goldfiish [28.3K]
Electron affinity is the tendency of a metal to accept electrons. In a general battery, one terminal has a higher electron affinity than the other, which attracts more electrons towards it, as compared to the other terminal. This potential difference between terminals create the voltage of the battery.

In a Rutherford scattering experiment a target nucleus has a diameter of 1.34×10-14 m. The incoming α particle has a mass of 6.6
Rasek [7]

Answer:

E = 2.5 x 10⁻¹⁴ J

Explanation:

given,

diameter = 1.33 x 10⁻¹⁴ m

mass = 6.64 x 10⁻²⁷ kg

wavelength is equal to diameter

de broglie wavelength equal to diameter

         \lambda = \dfrac{h}{mv}

         1.33 \times 10^{-14}= \dfrac{6.626 \times 10^{-34}}{6.64 \times 10^{-27}\times v}

         v= \dfrac{6.626 \times 10^{-34}}{6.64 \times 10^{-27}\times 1.33 \times 10^{-14}}

              v = 7.5 x 10⁶ m/s

Kinetic energy is equal to

     E = \dfrac{1}{2}mv^2

     E = \dfrac{1}{2}\times 6.64 \times 10^{-27}\times (7.5\times 10^6)^2

            E = 2.5 x 10⁻¹⁴ J
