The kelvin temperature/scale i think
Geothermal, Wind ,Solar, and Water turbine.
I hope I helped.
The direction of a vector multiplied by a scalar is only affected if the scalar is negative, in which case the vector will now be in the opposite direction. If the scalar is positive, the vector will only change in magnitude
Answer:
W = 30 J
Explanation:
given,
Work done = 10 J
Stretch of spring, x = 0.1 m
We know,
dW = F .dx
we know, F = k x
![\int dW = \int_0^{0.1} k.x dx](https://tex.z-dn.net/?f=%5Cint%20dW%20%3D%20%5Cint_0%5E%7B0.1%7D%20k.x%20dx)
![W = \int_0^{0.1} k.x dx](https://tex.z-dn.net/?f=W%20%3D%20%5Cint_0%5E%7B0.1%7D%20k.x%20dx)
![W = k[\dfrac{x^2}{2}]_0^{0.1}](https://tex.z-dn.net/?f=W%20%3D%20k%5B%5Cdfrac%7Bx%5E2%7D%7B2%7D%5D_0%5E%7B0.1%7D)
![10 = k\dfrac{0.1^2}{2}](https://tex.z-dn.net/?f=10%20%3D%20k%5Cdfrac%7B0.1%5E2%7D%7B2%7D)
k = 2000
now, calculating Work done by the spring when it stretched to 0.2 m from 0.1 m.
![W = \int_{0.1}^{0.2} 2000 x dx](https://tex.z-dn.net/?f=W%20%3D%20%5Cint_%7B0.1%7D%5E%7B0.2%7D%202000%20x%20dx)
![W = 2000 [\dfrac{x^2}{2}]_{0.1}^{0.2} dx](https://tex.z-dn.net/?f=W%20%3D%202000%20%5B%5Cdfrac%7Bx%5E2%7D%7B2%7D%5D_%7B0.1%7D%5E%7B0.2%7D%20dx)
W = 1000 x 0.03
W = 30 J
Hence, work done is equal to 30 J.
The solution would be like
this for this specific problem:
<span>5.5 g = g + v^2/r </span><span>
<span>4.5 g =
v^2/r </span>
<span>v^2 = 4.5
g * r </span>
<span>v = sqrt
( 4.5 *9.81m/s^2 * 350 m) </span>
v = 124
m/s</span>
So the pilot will black out for this dive at 124
m/s. I am hoping that these answers have satisfied your query and it
will be able to help you in your endeavors, and if you would like, feel free to
