Forming ionic bonds study
Answer:
4515.49484 N
4329.10484 N
Explanation:
r = Radius of balloon = 4.4 m
m = Mass of balloon with instruments = 19 kg
g = Acceleration due to gravity = 9.81 m/s²
Volume of balloon

The Buoyant force = Weight of the air displaced

The buoyant force acting on the balloon is 4515.49484 N
Net force on the balloon

The net force on the balloon is given by 4329.10484 N
As the balloon goes up the pressure outside reduces as the density of air decreases while the air pressure inside the balloon is high hence, the radius of the balloon tend to increase as it rises to higher altitude.
I am a competitive figure skater. There are certain turns you can use such as a mowhawk, where you set one foot down that is facing the opposite direction from which you are gliding. There is a two foot turn, where you either go on or toes and turn backwards, or lean somewhat on your heals and turn forwards. Use your hips to help turn. And a 3 turn, which is basically a 2 foot turn on 1 foot. But remember, it takes practice, and you may fall a couple times.
Answer:
the answer is gravitational force hope this helps u stay safe
Explanation:
You pick a system for which no control sample exists, so that no one can show that the alleged causal relationships you assert do not, in fact, lead to the phenomenon you claim to have observed.
