Answer:

im sure your already past this but it's E.

Explanation:

This is because in this case potential energy is linear to height, which means that the higher the more potential energy.

side of cube=4cm

Area=side^2=4^2=16cm^2=0.0016m^2

Force=144N

$\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}$

$\\ \sf\longmapsto Pressure=\dfrac{144}{0.0016}$

$\\ \sf\longmapsto Pressure=90000Pa$

i will give the brainliest answer to whoever answers this, explain how Sir William Gilbert used models in his investigation of m

levacccp [35]

Explanation:

Lodestone am iron were the only known magnetic materials in Gilbert's day, and his task was to investigate magnetism. Gilbert was so sure that the earth was a giant lodestone and used the earth as a primary reference, defining the north(magnetic) pole of a needle, or a a nail floating on a piece of cork, to be that which turns towards the Earth's north geographic pole. he wanted to prove this with a model Terella, using short pieces of iron.

Aluminum wire 1.00 mm in radius is to be used to construct a solenoid 15.0 mm in radius so that the magnitude of the magnetic fi

Leto [7]

To solve this problem we will proceed to use the equations given for the calculation of the resistance, in order to find the radius of the cable. Once the length is found we can find the number of turns of the solenoid and finally the net length of it

The resistance of the wire is

$R= \frac{\rho L}{A}$

$\rho$ = Resistivity

L = Length

A = Cross-sectional Area

That can be also expressed as,

$R = \frac{\rho L}{\pi r^2}$

Rearranging the equation for the length of the wire we have

$L= \frac{R\pi r^2}{\rho}$

$L= \frac{3\Omega \pi(1*10^{-3})}{2.655*10^{-8}\Omega \cdot m}$

$L = 354.8m$

The number of turns of the solenoid is

$N = \frac{L}{2\pi r} \rightarrow$ Denominator is equal to the circumference of the loop

$N = \frac{354.8}{2\pi(15*10^{-3})}$

$N = 3766$

Finally the Length of he solenoid is

$l = N (\phi)$

Where \phi is the diameter of wire

$l = N (2r)$

$l = (3766)(2*(1*10^{-3}))$

$l = 7.532m$

Therefore the length of the solenoid is 7.532m

Which set of shapes contains members that are always similar to one another?

Colt1911 [192]

<span>The correct answer is option C. i.e.Equilateral triangles. All equilateral triangle have equal sides. Due to this these set of shapes will always be similar. Similarity in the sense that only the size of the triangles can change to large or smaller but the shape will be be similar always.</span>
