Answer:

In the chances of contradiction.

Explanation:

Contradiction is defined as the incompatibility between the two or more prepositions. It occurs when the two proposition take together and there will be huge difference in two results and the two results are opposing each other.

When the result is compare with the other result or any given scientific result then the relation between these two oppose each other.

Therefore, if the two data contradicts with each other then there will be more probability to revised that scientific idea.

What is the average velocity of the object between 14 and 22 seconds?

Slav-nsk [51]

-1.1m/s

Explanation:

Work out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V). If you have U, A and T, use V = U + AT. If you have S, U and T, use V = 2(S/T) - U.

hello

Explanation:

for average speed the total distance is important so.

and you must convert min to hour 15 min is 1/4 or 0.25 hour

$s = \frac{x}{t} = \frac{12}{0.25} = 48 \frac{km}{h}$

for average velocity the straight line distance is important so

$v = \frac{d}{t} = \frac{8}{0.25} = 32 \frac{km}{h}$

hope you understand

A sound wave has a frequency of 645 Hz in air

rodikova [14]

Answer:

$-14.2^{\circ}C$

Explanation:

First of all, we can find the speed of the sound wave, which is given by:

$v=f \lambda$

where

f = 645 Hz is the frequency

$\lambda=0.5 m$ is the wavelength

Substituting,

$v=(645 Hz)(0.5 m)=322.5 m/s$

Now we can find the temperature of the air by using the following relationship:

$v = 331 m/s + 0.6 T$

where T is the temperature in Celsius degrees. Since we know v = 322.5 m/s, we can re-arrange the formula to find the temperature:

$T=\frac{v-331 m/s}{0.6}=\frac{322.5 m/s-331 m/s}{0.6}=-14.2^{\circ}C$

According to our present theory of solar system formation, why were solid planetesimals able to grow larger in the outer solar s

nirvana33 [79]

Answer:

According to our present theory of solar system formation, why were solid planetesimals able to grow larger in the outer solar system than in the inner solar system? Because only metal and rock could condense in the inner solar system, while ice also condensed in the outer solar system.
