A car is travelling around a circular track at a steady speed. A force causes it to follow the track.

1 answer:

4 0

The force that keeps the car moving in a circle is perpendicular to the car's velocity. The force points toward the center of the circle. The angle is <em>90°</em>.

The diagram that illustrates my answer is attached hereunto.

15.3 comparing planetary motion compare and contrast the different types of planetary motion

Goryan [66]

There are only two types of planetary motion and these kinds are revolution and rotation. Revolution is the act of the planets in the solar system to move around or "revolve" around the sun while rotation is done in which the planet "rotates" on its axis. In addition, the earth revolves around the sun in 365 and 1/4 days.

Davisson and Germer performed their experiment with a nickel target for several electron bombarding energies. At what angles wou

pochemuha

Answer:

The angle of diffraction are 67.75 deg and 53.57 deg.

Explanation:

Given:

Davisson and Germer experiment with nickel target for electrons bombarding.

Voltages : $38\ eV$ and $54\ eV$

We have to find the angles that is $\phi_3_8$ and $\phi_5_4$ .

Concept:

Davison Germer experiment is based on de Broglie hypothesis where it says matter has both wave and particle nature.
When electrons get reflected from the surface of a metal target with an atomic spacing of $D$ , they form diffraction patterns.
The positions of diffraction maxima are given by $Dsin(\phi) = n\lambda$ .
An atomic spacing is $D = 0.215\ nm$ , when the principal maximum corresponds to n=1
The wavelength is $\lambda$ , and $\lambda =\frac{1.227 \sqrt{V} } {\sqrt{V_o}}\ nm$ .
