The gravitational force between earth and the sun is a two-way force. both the planet and the sun attract each other. however, earth revolves around the sun rather than the sun revolving around earth. which statement best explains the orbit of the earth around the sun? a) the sun is at the center of the solar system. b) the sun’s mass is much greater than earth’s. c) earth rotates about its axis, but the sun does not. d) other planets also try to move the sun around them.

The correct choice would be

B)The Sun’s mass is much greater than Earth’s

The sun as we know has greatest mass in our solar system and lighter objects tends to orbit around the heavier objects. the mass of earth is very much smaller as compared to that of the sun. hence the earth orbits around the sun due to the force of gravitational attraction between the two objects.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

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
