How long does it take for sound to travel 28 miles

Sergeeva-Olga [200]3 years ago
5 0

Answer:

It takes roughly 140 seconds or roughly 2 minutes and 20 seconds for sound to travel 28 miles.

Explanation:

So, sound travels 1 mile in roughly 5 seconds.

To find out how long it takes for sound to travel 28 miles, multiply 28 by 5 (I'm pretty sure you know math!) So it takes roughly 140 seconds or roughly 2 minutes and 20 seconds for sound to travel 28 miles. (Remember! This is according to math, not science!) I hope you are safe! (Because this has been written during the corona virus times.) Please stay at home! =)

Parallel rays from a distant object are traveling in air and then are incident on the concave end of a glass rod with a radius o
skad [1K]

Answer:

the distance of image from the vertex is 45 cm and the image formed is in the glass.

Explanation:

distance of object, u = - infinity

radius of curvature, R = - 15 cm

refractive index, n = 1.5

Let the distance of image is v.

Use the formula

-\frac{n1}{u}+\frac{n2}{v}=\frac{n2- n1}{R}\\\\-\frac{1}{\infty }+\frac{1.5}{v}=\frac{1.5-1}{-15}\\\\v=45   cm

The image is in the glass.

A speed skater goes around a turn with a 31 m radius. The skater has a speed of 14 m/s and experiences a centripetal force of 46
dybincka [34]

Answer:

Mass of the skater, m = 72.75 kg

Explanation:

It is given that,

Radius of the circular path, r = 31 m

Speed of the skater, v = 14 m/s

Centripetal force, F = 460 N

We need to find the mass of the skater. It can be determined using the formula of centripetal force. It is given by :

F=\dfrac{mv^2}{r}

m=\dfrac{Fr}{v^2}

m=\dfrac{460\ N\times 31\ m}{(14\ m/s)^2}

m = 72.75 kg

So, the mass of the skater is 72.75 kg. Hence, this is the required solution.
