It was a dark and stormy night.Buffy hameard thunder exactly 6 secounds after she saw lightning , the temperature of air is 15°C

SashulF [63]

Answer:

υ = 345.82 m/s

Explanation:

The formula used to find the speed of sound in air, at different temperatures is given as follows:

$v = v_{0}\sqrt{\frac{T}{273} }$

where,

υ = speed of sound at given temperature = ?

υ₀ = speed of sound at 0°C = 331 m/s

T = temperature in K = 15°C + 273 = 298 k

Therefore, using these values in the equation, we get:

$v = (331 m/s)\sqrt{\frac{298 k}{273 k}}\\$

How does weak background radiation coming from every direction in the sky support the big bang theory

postnew [5]

Answer:

Option 1

It provides evidence of universe expansion

Explanation:

The Big Bang Theory actually explains the universe as originating from a single point, which expanded as billions of years went by.

The background radiation supports this theory in the sense that if the universe is expanding, this means that the universe is cooling and continuously losing heat, which results in background radiation

You and your roommate are moving to a city360 mi away. Your roommate drives a rental truck at a constant 50 mi/h , and you drive

AnnyKZ [126]

Answer:

42 minutes

Explanation:

First, let us find out the time required by the roommate, who is driving the truck, to reach the city.

We know that,

$time=\frac{distance}{speed} =\frac{360}{50} hrs=7.2hrs$

Now, you are planning to rest a bit after traveling for an hour. So,

distance covered in that 1 hour = $60mi/h\times1h=60 miles$

time required by you to cover the total distance = $\frac{360mi}{60mi/h} =6hours$

If you wish reach at the destination half an hour (0.5 h) before your roommate, you can expend a total of $7.2-0.5=6.7hours$ throughout your journey.

Hence, you can rest for $6.7-6=0.7hours=(0.7\times60)minutes=42minutes$
