• m/s²
• N/kg
• s²/m
• B
• (optional)

Answer explanation

Explanation for the answer (optional)

A vector quantity has...

• only direction
• both magnitude and direction
• no unit
• C
• Pluto

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.
