The answer is:

Matter & Energy

NEITHER MATTER NOR ENERGY CAN BE CREATED NOR DESTROYED BUT THEY CAN BE CHANGED FROM ONE FORM TO ANOTHER.

This is the law of energy created by Julius Lothar Meyer, a german chemist

He also created the first periodic table...

Answer:

ionized particles from the sun.

* interactions in radiation belts.

* the friction of the planet in the solar wind

q = +9 10⁵ C

Explanation:

Due to being made up of matter, the planet Earth has a series of positive and negative charges, in general these charges should be balanced and the net charge of the planet should be zero, but there are several phenomena that introduce unbalanced charges, for example:

* ionized particles from the sun.

* interactions in radiation belts.

* the friction of the planet in the solar wind

This creates that the planet has a net electrical load

We can roughly calculate the charge of the planet

E = k q / r²

q = E r² / k

let's calculate

q = 200 (6.37 10⁶)²/9 10⁹

q = +9 10⁵ C

The parallel axis theorem relates Icm, the moment of inertia of an object about an axis passing through its center of mass, to I

erma4kov [3.2K]

Answer:

Part a)

$I_{end} = \frac{mL^2}{3}$

Part b)

$I_{edge} = \frac{2ma^2}{3}$

Explanation:

As we know that by parallel axis theorem we will have

$I_p = I_{cm} + Md^2$

Part a)

here we know that for a stick the moment of inertia for an axis passing through its COM is given as

$I = \frac{mL^2}{12}$

now if we need to find the inertia from its end then we will have

$I_{end} = I_{cm} + Md^2$

$I_{end} = \frac{mL^2}{12} + m(\frac{L}{2})^2$

$I_{end} = \frac{mL^2}{3}$

Part b)

here we know that for a cube the moment of inertia for an axis passing through its COM is given as

$I = \frac{ma^2}{6}$

now if we need to find the inertia about an axis passing through its edge

$I_{edge} = I_{cm} + Md^2$

$I_{edge} = \frac{ma^2}{6} + m(\frac{a}{\sqrt2})^2$

$I_{edge} = \frac{2ma^2}{3}$

Light intensity is?

Fittoniya [83]

The correct answer is:
The rate at which a waves energy flows through a given unit of area

In fact, light intensity is defined as the light power per unit of area:
 $I= \frac{P}{A}$
but the power is the energy carried by the light per unit of time:
 $P= \frac{E}{t}$
this means that the intensity can be rewritten as
 $I= \frac{E}{tA}$ 
So, it's basically the rate of energy (per unit of time) through a given surface.

How does the gravity which pulls the moon and earth toward each other also affect the ocean?

slamgirl [31]

Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
