Se realiza un experimento en el que se mide el alargamiento de un muelle debido a la acción de una pesa; se trata de comprobar la ley de Hooke. Los datos que se han obtenido son: Medición 1 2 3 4 5 Alargamiento 42.0 48.4 51.3 56.3 58.6 Masa 2 4 6 8 10 El coeficiente de determinación es:

m = 1,975 m / kg , b = 38.05 m

Explanation:

In this experiment, the elongation is plotted against the applied mass

getting a straight line

            y = m x + b

where b would be the initial length of spring let's calculate the slope for which we use two well separated points

           m = (56.3 -48.4) / (8 - 4)

           m = 1,975 m / kg

the equation remains

         y = 1,975 x + b

for x = 2 kg y = 42.0 m

we substitute in the equation

           42 = 1,975 2 + b

           b = 42 - 3.95

           b = 38.05 m

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
