G1) radiation is emitted from the sun over a wide range of wavelengths. consider visible light (wavelengths from 400 nm to 700 nm) that is emitted from the sun and received on earth (a great distance away). what are the gravitational redshifts (in nm) at 400 and 700 nm

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the answer would be c. motion and direction

i hope this : )

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
