Sunspots are dark because . a. the strong magnetic field inhibits the currents of hot gas rising from below. b. of shock waves moving through the photosphere. c. they have a different chemical composition than the rest of the sun. d. regions of the photosphere are obscured by material in the chromosphere.

a) the strong magnetic field inhibits the currents of hot gas rising from below.

Explanation:

Sunspots are dark because they are a little cooler than the photo sphere.

The magnetic field inhibits the strong rising currents of hot gas,allowing it to cool the surface.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
