Weight = (mass) x (acceleration of gravity).
On Earth, acceleration of gravity = 9.8 m/s² (rounded)
On Earth, 2.2kg of mass weighs (2.2kg) x (9.8 m/s²) =
21.6 kg-m/s² = <em>21.6 Newtons</em>.
(That's about 4.85 pounds.)
Answer:
it is the physics that explains how everything works. The best description we have of the. nature of the particles that make up matters and the forces with which they interact. It underlines how atoms work, and so why chemistry and biology work as they do
According to Boyle's Law, volume is inversely proportional to pressure. It means
if the volume of a gas goes up the pressure goes down and if the volume of the gas goes up the pressure goes down. When the pressure of air inside the inflated balloon is more than the atmospheric pressure outside the balloon. And also when the density inside is greater than the density outside. The molecules inside the balloon move and bang around the inner walls which produces force, which provides the pressure of an enclosed air.
The approximate diameter of an inflated basketball is <span>2 × 10^–2 m. The answer is number 1. The rest of the choices do not answer the question above because they are too big for the diameter of the basketball.</span>
