What factors might affect how the watermill works?
sveta [45]
<span>Since a watermill is powered by a water wheel the strength of the current and volume of the water passing the mill may alter the amount of power provided. Seasonal and climatic changes could contribute to changes in the current.</span>

During most of its lifetime, s star maintains an equilibrium size in which the inward force of gravity on each atom is balanced
frez [133]

Answer:

r_f=137493m

v=8638940m/s

Explanation:

During this process the mass M=2\times10^{30}Kg will be considered constant. We start from a radius r_i=7\times10^8m and a period T_i=30\ days=(30)(24)(60)(60)s=2592000s. The final period is T_f=0.1s.

Angular momentum <em>L</em> is conserved in this process. We can use the formula L=I\omega, where I is the momentum of inertia (which for a solid sphere is I=\frac{2mr^2}{5}) and \omega=\frac{2\pi }{T} is the angular velocity, so we can write the star's angular momentum as:

L=I\omega=\frac{2mr^2}{5}\frac{2\pi }{T}=\frac{4\pi mr^2 }{5T}

Since L_f=L_i we have:

\frac{4\pi mr_f^2 }{5T_f}=\frac{4\pi mr_i^2 }{5T_i}

Which can be simplified as:

\frac{r_f^2 }{T_f}=\frac{r_i^2 }{T_i}

Which means:

r_f=\sqrt{\frac{r_i^2 T_f}{T_i}}=r_i \sqrt{\frac{T_f}{T_i}}

Which for our values is:

r_f=r_i \sqrt{\frac{T_f}{T_i}}=(7\times10^8m) \sqrt{\frac{0.1s}{2592000s}}=137493m

And we calculate the speed of a point on the equator by dividing the final circumference over the final period:

v=\frac{C_f}{T_f}=\frac{2\pi r_f}{T_f}=\frac{2\pi (137493m)}{(0.1s)}=8638940m/s

A negative charge is at rest at the origin of an axis system. Location x is at coordinate point (2m,3m) while location y is at (
Sergeu [11.5K]
The magnitude of the E-field decreases as the square of the distance from the charge, just like gravity.

Location ' x ' is  √(2² + 3²) = √13 m  from the charge.

Location ' y ' is √ [ (-3)² + (-2)² ] = √13 m from the charge.

The magnitude of the E-field is the same at both locations.

The direction is also the same at both locations ... it points toward the origin.
