Answer:

Astronomers have divided the eight planets of our solar system into the inner planets and the outer planets. The 4 inner planets are the closest to the Sun, and the outer planets are the other four – Jupiter, Saturn, Uranus, and Neptune. The outer planets are also called the Jovian planets or gas giants.

A bugle can be thought of as an open-end pipe. If a bugle were straightened out, it would be 2.65 m long. a. If the speed of sou

vitfil [10]

Answer

given,

Length of pipe, L = 2.65 m

speed of sound, v = 343 m/s

Pipe is open end Pipe

a) Lowest frequency

condition, for open end pipe

$\lambda_1 = 2 L$

$\lambda_1 = 2\times 2.65$

$\lambda_1= 5.30 m$

For lowest frequency

$f_1 = n\dfrac{v}{\lambda_1}$

n = 1

$f_1 = \dfrac{343}{5.30}$

f₁ = 64.72 Hz

b) For second frequency in bugle

n = 2

$f_2 =2\times \dfrac{343}{5.30}$

f₂ = 129.43 Hz

for n = 3

$f_3 =3\times \dfrac{343}{5.30}$

f₃ = 194.16 Hz

A quarterback takes the ball from the line of scrimmage, runs backward for 12.1 yds, then runs sideways parallel to the line of

Over [174]

Answer:

The answer is 35.45 yds

Explanation:

You have to picture this to be able to understand it better (see attachment).

Start at the origin which is when the quarterback (QB) takes the ball. He runs backwards 12.1 yards, runs sideways for 19.8 yards (it doesn´t matter if he runs right or left), then he throws the ball forward 41.5 yards. If you look at the attachment, you can see I drew the path that the football followed. And then connected the dots from the origin and finish. The distance between those two points is the magnitude of the resultant displacement.

In order to calculate it, all you need to do is use the Pythagoream theorem, which says that the square of the hypotenuse equals the sum of the squares of the legs a and b of the triangle rectangle.

$R^{2} = a^{2} + b^{2}$ then solve for R
$R = \sqrt{a^{2}+b^{2} }$

In this case, you know the length of leg a to be 19.8 yards which how much it moves sideways. And then, to get the length of leg b, all you need to do is substract how much it moved backwards from the 41.5yards forward displacement. This results in b leg being 29.4 yards long.

Now you have a triangle with:

a = 19.8 yards
b = 29.4 yards

Substituting this numbers in the equation:

$R = \sqrt{19.8^{2}+29.4^{2} }$
R = 35.45 yards

Coherent light of frequency f travels in air and is incident on two narrow slits. The interference pattern is observed on a dist

svp [43]

Answer:

A) d = 6.1857 10⁻⁵ m

Explanation:

In the double-slit experiment the constructive interference is given by the expression

d sin θ = m λ

d = $\frac{m \lambda }{sin \theta}$

let's use the relationship between speed, wavelength and frequency

c = λ f

λ = c / f

λ = 3 10⁸ / 5.60 10¹²

λ = 5.357 10⁻⁵ m

I do not know India in order of interference, we will assume that m= 1

d = 1 5,357 10⁻⁵ / sin 60

d = 6.1857 10⁻⁵ m
