To convert minutes to hours we divide the minutes by 60. So if we divide 3 by 60 we get 0.05 hours.
<h3>How to convert minutes into hour?</h3>
We know that in hour, there are 60 minutes so if we go from minutes to hours then we have to divide the number by 60 and when we go from hours to minutes we multiply with the same 60 number.
So we can conclude that to convert minutes to hours we divide the minutes by 60. So if we divide 3 by 60 we get 0.05 hours.

Answer:
0.071 is the correct answer using the formula d=m/v
The answer is 4.89
The explanation:
when the Kb of ((HOC2H2)3N) = 5.9 x 10^-7
1- we can get the value of Ka from Kb:
when Ka = Kw / Kb
= 1 x 10^-14 / 5.9 x 10^-7
= 1.69 x 10^-8
2- now we will calculate the [H+] value:
when [H+] = √(Ka*[HA])
=√((1.69E-8)(0.010))
= 1.3 x 10^-5 M
3- the final step we will calculate the PH value from the value of [H+]:
PH = - ㏒ [H+]
= - ㏒ 1.3 x 10^-5
= 4.89
Answer:
E. it has almost no atmosphere.
Explanation:
On Mercury, where there is no atmosphere there is no weather to erode away the craters, So most of the craters are there on its surface.
Hope it helps :)
The model of light does the example supports is the particle model.
<h3>What is the wave-particle duality model of light?</h3>
The wave-particle duality model of light is a model which suggests that light behaves both as a [article and as a wave.
The wave-like property is seen in its properties such as reflection, refraction, diffraction, etc.
The particle nature of light is seen in the photoelectric effect and the Compton effect.
Light shining on solar cells produces a current that charges a solar calculator is an example of the photoelectric effect.
Therefore, the model of light does this example support is the particle model.
