What type of energy does a pv cell create ?
Alex_Xolod [135]

Answer:  Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your school, home and businesses.

What is the most significant challenge for organisms that live in estuaries?
marysya [2.9K]

"Changing water salinity" is the most significant challenge for organisms that live in estuaries.

<u>Answer:</u> Option D

<u>Explanation:</u>

For estuaries, alkalinity levels are usually the maximum at a river's mouth where the ocean water falls for, and the minimum upstream where freshwater falls in. Although salinity vary throughout the tidal cycle. In estuaries, salinity rates usually decrease in spring as snow melt and rain raises the freshwater flow from streams and groundwater.

It influences the chemical environments within the estuary, especially the dissolved oxygen (DO) levels in the water. The level of oxygen that would get dissolved in water or its solubility get declined when the alkalinity rises.

a student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a
kozerog [31]

Given:

Force, f = 12 \frac{kg-m}{sec^{2} }

Mass, m = 7 kg

Acceleration, a_{1} = 3\;\frac{m}{sec^{2} }

a = a_{1}+\frac{f}{m}

Substitute\;the\;values\;of\;f,\;m\;and\;a_{1}\;in\;the\;above\;equation,

a = 3+\frac{12}{7}

a = 3 + 1.714

Therefore, the acceleration is,

a = 4.714\;\frac{m}{sec^{2} }

<h3>Explain Acceleration?</h3>

An object's rate of changing its velocity is known as its acceleration, which is a vector quantity. If an object's velocity is changing, it is accelerating. When anything moves faster or slower in a straight line, it is said to have been accelerated. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
