Explanation:
Neptune would have a slower orbit i just did this
Answer: ice float in water due to density differences. Water has a higher density than ice.less dense object in liquid with high density
Explanation: from density formulae.
D=M/V
Density of ice =Mass of ice/Volume of ice
D=23/25
D=0.92g/cm^3
Answer: Electric field vector is created by an electric force of a charged particle.
Explanation: The direction of the field vector can be determined by applying Coulomb’s Law which explains the electric force between charge particles. If q is positive the force is repulsive, to a test charge ( which is positive always ) and if q is negative the force is attractive to a test charge.
