Heat<span> flux is a quantitative, vectorial representation of </span>heat-flow<span> through a surface. ...</span>Heat transfer<span> is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and </span>transfer<span> of energy by phase changes.</span>
The gravitational force between earth and moon will increase.
by F = GMm/r^2
F is inversely proportional to r^2
when r decrease, F will increase.
D) Scientific laws do not account for unseen variations, like wind
Explanation:
Will model in predicting the path of an arrow he was about to shoot failed because scientific laws most times do not account for unseen variations like wind.
Scientific laws are the description of an observed phenomenon in nature.
- Most scientific laws have exceptions.
- Exceptions in scientific laws are conditions in which the law will not hold true.
- There are exceptions to newton's law of motion which Will did not take into account.

The formula for the period of wave is: wave period is equals to 1 over the frequency.
![waveperiod=\frac{1}{frequency}](https://tex.z-dn.net/?f=%20waveperiod%3D%5Cfrac%7B1%7D%7Bfrequency%7D%20)
To get the value of period of wave you need to divide 1 by 200 Hz. However, beforehand, you have to convert 200 Hz to cycles per second. So that would be, 200 cyles per second or 200/s.
By then, you can start the computation by dividing 1 by 200/s. Since 200/s is in fractional form, you have to find its reciprocal form and multiply it to one which would give you 1 (one) second over 200. This would then lead us to the value
0.005 seconds as the wave period.
wave period= 1/200 Hz
Convert Hz to cycles per second first
200 Hz x 1/s= 200/second
Make 200/second as your divisor, so:
wave period= 1/ 200/s
get the reciprocal form of 200/s which is s/200
then you can start the actual computation:
wave period= 1 x s divided by 200
this would give us an answer of
0.005 s.
Answer:
4v/3
Explanation:
Assume elastic collision by the law of momentum conservation:
![m_1v = m_1v_1 + m_2v_2](https://tex.z-dn.net/?f=m_1v%20%3D%20m_1v_1%20%2B%20m_2v_2)
where v is the original speed of car 1, v1 is the final speed of car 1 and v2 is final speed of car 2. m1 and m2 are masses of car 1 and car 2, respectively
Substitute ![m_2 = m_1/2 \& v_1 = v/3](https://tex.z-dn.net/?f=m_2%20%3D%20m_1%2F2%20%5C%26%20v_1%20%3D%20v%2F3)
![m_1v = \frac{m_1v}{3} + \frac{m_1v_2}{2}](https://tex.z-dn.net/?f=m_1v%20%3D%20%5Cfrac%7Bm_1v%7D%7B3%7D%20%2B%20%5Cfrac%7Bm_1v_2%7D%7B2%7D)
Divide both side by
, then multiply by 6 we have
![6v = 2v + 3v_2](https://tex.z-dn.net/?f=6v%20%3D%202v%20%2B%203v_2)
![3v_2 = 4v](https://tex.z-dn.net/?f=3v_2%20%3D%204v)
![v_2 = \frac{4v}{3}](https://tex.z-dn.net/?f=v_2%20%3D%20%5Cfrac%7B4v%7D%7B3%7D)
So the final speed of the second car is 4/3 of the first car original speed
