Answer:

The sun.

Explanation:

Although the organisms on the earth who require energy are diverse, they truly all rely on one big source: the sun. Sunlight is vital to the process of photosynthesis performed by plants which supplies oxygen and glucose needed for the survival of all living beings on the Earth.

What is the effect of a larger acceleration on launch velocity?

vredina [299]

Answer:

Concept: Physical Concepts

A larger acceleration, which is the change in velocity divided by the change in time is the theta or the angle that it climbs to.
Secondly the launch velocity is higher or faster and traveles a further distance.

Light waves travel through space

VladimirAG [237]

C.even though there is almost no material in the interstellar medium, but do transfer energy.

Explanation:

Light waves travels through space even though there is almost no material in the interstellar medium but do transfer energy.

A wave is any disturbance that transmits energy from one place to another.

Light is a form of wave which belongs to the electromagnetic spectrum.
They are propagated transverse to their source of energy.
These electromagnetic waves are special types of waves.
They are distinct because they do not require a material medium for their propagation unlike other waves.
In the interstellar medium. a vacuum is in place.
There are no matter that can be used for propagating waves.
Light waves still passes through because they do not require any medium to propagate.

What happens when an electron moving from the 3rd energy level to the 1st energy level?

Sholpan [36]

Answer:

A photon of wavelength 103 nm is released

Explanation:

When an electron in an atom jumps from a higher energy level to a lower energy level, it releases a photon whose energy is equal to the difference in energy between the two levels.

For example, if we are talking about a hydrogen atom, the energy of the levels are:

$E_1 = -13.6 eV\\E_2 = -3.4 eV\\E_3 = -1.5 eV$

So, the energy of the photon released when the electron jumps from the level n=3 to n=1 is

$\Delta E = E_3 - E_1 = -1.5 -(-13.6)=12.1 eV$

In Joules,

$\Delta E =12.1\cdot 1.6\cdot 10^{-19} = 1.94\cdot 10^{-18} J$

We can also find the wavelength of this photon, using the equation:

$\Delta E = \frac{hc}{\lambda}\rightarrow \lambda=\frac{hc}{\Delta E}=\frac{(6.63\cdot 10^{-34})(3\cdot 10^8)}{1.94\cdot 10^{-18}}=1.03\cdot 10^{-7} m = 103 nm$

Draw an arrow that points from the earth pole toward polaris

IRINA_888 [86]

The polaris is a star which appear to stand still while the rest of the stars move due to the rotation of the earth.If u are standing at the north pole the polaris would be directly above you.To find the polaris u must first find the big dipper which is like a bowl with handle and the move like 5 time to find the polaris
