A basketball player pushes down with a force of 34 N on a basketball thats inflated 9x10^4 Pa. What is the contact diameter between the ball and the floor?

d= 0.0219m

Explanation:

P= force /area

Area =πr^2=πd^2/4

πd^2/4=force/pressure

πd^2/4=34/90000

πd^2/4=0.0003778

πd^2= 0.0003778*4

πd^2=0.001511

Since π=3.142

d^2= 0.001511/3.142

d^2= 0.000480

d= square root of 0.000480

d= 0.0219m

answer; /// the above statement is (true);

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
