Aballoon is a sphere with a radius of 5.0 m. the force of air against the walls of the balloon is 45 n. what is the air pressure inside the balloon? (surface area = 12.56 x radius^2; 1 pa = 1 n/m^2)

a. 1.4 x 10^3 pa

b. 3.6 x 10^2 pa

c. 1.4 x 10^-1 pa

d. 3.6 x 10^-2 pa

***idk how to solve pls explain? ? thx : )

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
