Explanation:

Complete the first and second sentences, choosing the correct answer from the given ones.

1. T = 100 K

^{\circ}C=K-273

Put T = 100 K

T=100-273=-173^{\circ} C

A temperature of 100 K corresponds on a Celsius scale to (-173 °C)

2. T = 50 °C

K=^{\circ}C+273\\\\K=50+273\\\\T=323\ K

So, At 50 °C, it corresponds to a Kelvin scale of 323 K.

6. An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speed of t
Ymorist [56]

Answer:

The distance away the center of the earthquake is 1083.24 km.

Explanation:

Given that,

Speed of transverse wave = 9.1\ km/s

Speed of longitudinal wave = 5.7 km/s

Time = 71 sec

We need to calculate the distance of transverse wave

Using formula of distance

d=v\times t

d=9.1\times t....(I)

The distance of longitudinal wave

d=5.7\times (t+71)....(II)

From the first equation

t=\dfrac{d}{9.1}

Put the value of t in equation (II)

d =5.7\times(\dfrac{d}{9.1}+71)

\dfrac{9.1d-5.7d}{9.1}=71\times5.7

d0.3736=404.7

d =1083.24\ km

Hence, The distance away the center of the earthquake is 1083.24 km.

Imagine That Kevin can instantly transport himself between Planet X and planet Y. Which statement could be said about Kevin in t
Svetradugi [14.3K]

When Kevin pulls off this stunt, his average speed is (distance) / (time).

So, whatever the distance may be, his average speed for the trip is

(some distance)/0 = infinite speed.

Now, stay with me here:

His acceleration at the beginning of the trip is

(change in speed) / (time to change)

Whatever speed he started at, his acceleration had to be

(infinite change in speed)/(no time).

That's a big acceleration doncha know.

He needed an infinite force and an infinite amount of energy from somewhere to achieve that acceleration, and as soon as he started accelerating, his insides got totally shredded.

Whatever arrived on Planet-Y looked like a pile of overcooked pasta.

It wasn't worth the trip.
