Find the angular displacement of 8.3 revolutions.

16.6π rad

Step-by-step explanation:

Angular displacement is how much degree in radian has been covered by revolving.

So,angular displacement=8.3 revolutions

We know that, 1 revolution = 2π rad

angular displacement = 8.3 × 2π

= 16.6 π rad

answer: 5000

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
