Question

a) a soccer team scores 3 goals in 90 minutes

b) a pendulum swings 30 times in 20 seconds

c) a jackhammer strikes the ground 200 times in one minute

Answer 1

a) f =3/90•60=5.56•10^-4 s^-1.
b) f = 30/20 = 1.5 s^-1.
c) f = 200/60 = 20/300 =3.33 s^-1

Answer 2

so would

A) fgnq3o;4y96983pgdisp8y8t475-65;7-9

B) gqfg-r;r-7[9=]7=y63640687kh

c) jhgwg-906490-19384658302((*&^%$#@

right?

Answer 3

What is this ??????????????

Answer 4

I asked to figure the Period out of those numbers. :P

Answer 5

T=1/f
T1 = 1/5.56•10^-4 = 1799 s.
T2= 1/1.5 = 0.667 s.
T3 = 1/3.33 = 0.3 s
