Physics Paper 2 - MEGAMIX

What is the unit of force?

• Newton (N)
• Watt (W)
• Joule (J)
• Pascal (Pa)

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.
