Why is Melanie's diagram of the phases of the moon incorrect? First quarter moon should be between the sun and Earth. Third quar

ter moon should be between the sun and Earth. The position of the full moon and new moon have been interchanged. The position of the first quarter moon and third quarter moon have been interchanged.

Before we can spot what's wrong with it, we would need to actually SEE the diagram. It's the only way.

A proton is trapped in a one-dimensional well that is 200 pm wide. What is the ground state energy of the proton, if the potenti
Harrizon [31]

Answer:

E=1.50\times 10^{-18}J

Explanation:

Energy of the one dimensional infinite well,

E=\frac{n^{2}h^{2} }{8mL^{2} }

Given that, L=200 pm\\L=200\times 10^{-12}m

For the ground state n=1,

Therefore energy is,

E=\frac{(6.626\times 10^{-34})^{2}}{8(9.1\times 10^{-31})(200\times 10^{-12}) ^{2} }\\E=1.50\times 10^{-18}J

Calculate the electric field on the surface of a charged sphere with a radius of 5cm and charge 10μC. Thanks
victus00 [196]

As you approach the surface of the sphere very closely, the electric field should resemble more and more the electric field from an infinite plane of charge.

If you check Gauss's law (recalling that the field in the conductor is zero) you will see that if the surface charge density is σ=Q/4πR2, then indeed the field at the surface is σ/ϵ0 as in the infinite charge of plane case.

Such a field is constant, the field lines are parallel and non-diverging, and the infinities associated with the field due to point charge do not arise.

A 111 kg 111 kg horizontal platform is a uniform disk of radius 1.67 m 1.67 m and can rotate about the vertical axis through its
Mashcka [7]

Answer:

287.19 kg.m²

Explanation:

Given that :

The mass M of the horizontal platform  = 111 kg

The radius R of the uniform disk = 1.67 m

mass  of the person standing m_p = 64.7 kg

distance of the person standing d_p = 1.15 m

mass of the dog m_d = 25.7 kg

distance of the dog d_d = 1.35 m

Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:

=  \frac{MR^2}{2}+m_pd_p^2+m_dd_d^2

= (\frac{111*1.67^2}{2})+ (64.7 *1.15^2)+ (25.7*1.35^2)

= 287.19 kg.m²
