Answer:
4.7 × 10⁵J
Explanation:
E = I * a * t
80% = 0.80
25cm = 0.25m
52cm = 0.52m
0.90h = 3240s
E = (0.80)(1400)(0.25 * 0.52)(3240)
= 4.7 * 10⁵J
Answer:
x-component = 7.1
Explanation:
x-component = 9cos38 = 7.09 =7.1
<span>The choices can be found elsewhere and as follows:
</span><span>a. they are so small that they stay close to the ground due to the attractive properties of charged soil particles.
b. they are easily carried by the wind.
c. they easily dissolve in liquid droplets.
d. it is easier for then to roll along the small crevices in the ground.</span><span>
</span>I think the correct answer from the choices listed above is option B. Only the smallest particles of soil can be displaced by suspension because they are so small that they are easily carried by the wind. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Answer: hypothesis that is not supported by the results of an experiment may lead to further research and investigations.
