True or False: Stress can effectively be relieved through physical activity, getting enough rest and sleep, and relaxation techn
Neko [114]

Answer:

True

Explanation:

Actually this are some of the nitty gritty answers and ways to control or stip stress, lemme explain them you see stress most of the time may come from deep thoughts that are and are pushing you to the wall, and you in your state you as you react to that which is so demanding as it makes you tense,so if at you will incorporate physical activities like running, jogging or push ups the psychological tension in you is broken as you focus so much on the activities rather than the tension, then getting enough rest cools the mind and all your thoughts settle as in your brain starts to adapt to chilling and relaxation and enough sleep will actually make ones head to be at peace because if you lack enough sleep you might have an excruciating migraine when you are stressed up and finally relaxation techniques makes the body accept the situation and then you manouver out of it as you grow strongly.

Hope this will help!

The following is a correlation for the average Nusselt number for natural convection over spherical surface. As can be seen in t
vovikov84 [41]

Answer:

Explanation:

r_2=∞

q=4\pi kT_1(T_2-T_1)\\

q=2\pi kD.ΔT--------(1)

q=hA ΔT=4\pi r_1^2(T_2_s-T_1_s)\\

N_u=\frac{hD}{k} = 2+\frac{0.589 R_a^\frac{1}{4} }{[1+(\frac{0.046}{p_r}\frac{9}{16} )^\frac{4}{9}  }  ------(3)

By equation (1) and (2)

2\pi kD.ΔT=h.4\pi r_1^2ΔT

2kD=hD^2\\\frac{hD}{k} =2\\N_u=\frac{hD}{k}=2\\-------(4)

From equation (3) and (4)

So for sphere R_a→0
