Scientists have designed solar cells to trap solar energy and convert it to D electrical energy. Its D because converting something has to do with recharging something and electronics have to charge. I hope I helped.
There is 4000 balls in the earth of the world why is that so hard for you
Atmosphere
Atmospheric gas from prehistoric eras is found trapped in glaciers in the form of bubbles. These gas bubbles are the basis of studying ice cores as they provide us with accurate estimates of the conditions of past climates. The bubbles allow us to determine the composition of atmospheric air, such as the carbon dioxide and methane concentrations, as well as allow us to determine air temperatures in the past.
Explanation:
where is your diagram? lol
Answer:
From the formula of force:
since AB and k are constants:
x is a constant of proportionality
• when force is 4N, separation distance is 1
therefore, equation becomes
when r is doubled, r becomes 2. find F:
