One solar panel produces a potential differenceof 20V and current 4A. Describe now you canobtain a potential difference of 80 Volts andcurrent of 12 A with a solar array using solarpanel. You can use sign of a battery for a solarpanel.​

Answer»

Answer:

In a ( 4 × 3 ) COMBINATION

Explanation:

ONE solar panel  [ 20V   4A ]

If connected in series, then potential difference gets added

    ⇒ V = V₁ + V₂  But current remains the same i.e. I = I₁ = I₂

If connected in parallel, then current gets added

   ⇒ I = I₁ + I₂        But potential difference remains the same i.e. V =  V₁ = V₂

Thus FIRST we can obtain 80 V by connecting 4 such solar panels in series

 ( 20 V × 4 = 80 V )

Now, we can obtain 12 A by connecting such 3 sets of 4 panels in parallel combination

( 4 A × 3 = 12 A )

Roughly, the solar array will look like  this

         ---║--║--║--║--  

         ---║--║--║--║--  

         ---║--║--║--║--  

         ---║--║--║--║--  

Thus, we get the required potential difference and current

You can see the attachment for clear understanding

5 scientific ways to decrease india's population???​

Answer»

Answer:

5 ways to reduce population

Empower women

Studies show that women with access to reproductive health services find it easier to

break out of poverty, while those who work are more likely to use birth control.

2. Promote family planning

Simply educating men and women about contraception can have a big impact. When Iran introduced a national family planning programme in 1989, its fertility rate fell from 5.6 births per woman to 2.6 in a decade. A similar effort in Rwanda saw a threefold increase in contraception usage in just five years.

3. Make education entertaining

The US-based Population Media Center gets creative to reach women. Its radio soap operas, which feature culturally specific stories about reproductive issues, have been heard by as many as 500 MILLION people in 50 countries. In Ethiopia, 63 per cent of women seeking reproductive health services reported tuning in.

4. Government incentives

Those at UK charity Population MATTERS believe there should be a senior government official responsible for addressing population-related issues. They urge governments to promote “responsible parenthood” and say subsidies should be limited to the first two children unless the family is living in poverty.

5. One-child legislation

During China’s high controversial one-child policy, fertility fell from six births per woman in the 1960s to 1.5 in 2014. However, Amnesty International reports that the policy LED to COERCED or forced abortions and sterilisations. It also DISRUPTED traditional support structures for the elderly and led to a gender imbalance.

Answer»

Answer:

Facilitated transport

Facilitated DIFFUSION (also known as facilitated transport or passive-mediated transport) is the PROCESS of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane INTEGRAL proteins.

What will happen to red blood cells in 0.9% nacl solution

Answer»

Answer:The red blood cell has its normal volume in isotonic NaCl. ERYTHROCYTES remain intact in NaCl 0.9%, RESULTING in an opaque SUSPENSION. Distilled water on the other HAND is hypotonic to red blood cells. The red blood cell will therefore swell and haemoglobin, containing the haem that gives the red colour to erythrocytes, LEAKS from the cell resulting in a transparent red-pink-coloured solution.
