Answer:
a) 17.086m
b) 0.1671 m
Explanation:
Given data: speed of water through the hose = 1.81 m/s
through the nozzle = 18.3 m/s
We know that maximum height of an object with upward velocity v is given by,
a) H = v^2/2g
where H is the maximum height water emerges
= 18.3^2/(2×9.8) = 17.086 m answer
b) Again,
H = v^2/2g
= 1.81^2/(2×9.8) = 0.1671 m
Answer with Explanation:
We are given that
Current in conductor=I=4.99 A (-x direction)
Magnetic field=B=
(1mT=
)
x(in m) and B (in mT)
Length of conductor is given in negative x- direction
Force on current carrying conductor is given by
Integrating on both sides then we get
(
![\vec{F}=-(4.99\times 10^{-3}\times 8.72)[\frac{x^3\hat{k}}{3}]^{2.77}_{1.41}](https://tex.z-dn.net/?f=%5Cvec%7BF%7D%3D-%284.99%5Ctimes%2010%5E%7B-3%7D%5Ctimes%208.72%29%5B%5Cfrac%7Bx%5E3%5Chat%7Bk%7D%7D%7B3%7D%5D%5E%7B2.77%7D_%7B1.41%7D)
a. x- component of force=0
b.y- component of force=0
c.z- component of force=-0.268 N
When you do work to lift the object, the amount of work you do BECOMES the object's gravitational potential energy. It GETS its potential energy from the work you do to lift it. They're equal. You lose it, and the object gains it. Energy is not created or destroyed. It's just transferred from you to the object.
Later, when you DROP the object, GRAVITY does the same amount of work on it, to pull it to the ground. Again, no energy is created or destroyed. Every time a force acts to move anything, the energy to do it comes from somewhere, and the energy goes somewhere.
Answer:
5.88×10⁸ W
Explanation:
Power = energy / time
P = mgh / t
P = (m/t) gh
P = (1.2×10⁶ kg/s) (9.8 m/s²) (50.0 m)
P = 5.88×10⁸ W
The Generator transforms the mechanical energy of the turbine into electrical energy.
