Explanation:

The correct answer is: (Option D) 6.22 N

Explanation:

By using the <em>Newton's second law</em>:

F = Force = ?

m = mass = 0.42 kg

a = acceleration = 14.8 $\frac{m}{s^2}$

Plug the values in equation (A):

F = 0.42 * 14.8

F = 6.216 N

$F \approx 6.22 N$ (Option D)

Which statement best explains how a planet affects the orbit of a comet as the comet passes by the planet?

mezya [45]

Comets orbit the sun just like planets do. Except a comet usually has a very elongated orbit. Thanks to the laws of gravity comets obey the same laws. A comets orbit takes it very close to the sun and then far away again.

A diffraction pattern forms when light passes through a single slit. The wavelength of the light is 691 nm. Determine the angle

expeople1 [14]

Explanation:

Given that,

Wavelength of the light, $\lambda=691\ nm=691\times 10^{-9}\ m$

(a) Slit width, $a=3.8\times 10^{-4}\ m$

The angle that locates the first dark fringe is given by :

$sin\theta=\dfrac{\lambda}{a}$

$sin\theta=\dfrac{691\times 10^{-9}}{3.8\times 10^{-4}}$

$\theta=0.104^{\circ}$

(b) Slit width, $a=3.8\times 10^{-6}\ m$

The angle that locates the first dark fringe is given by :

$sin\theta=\dfrac{\lambda}{a}$

$sin\theta=\dfrac{691\times 10^{-9}}{3.8\times 10^{-6}}$

$\theta=10.47^{\circ}$

Hence, this is the required solution.
