Which has a mass that is best measured in grams a a watermelon b a donkey c a car d a pencil

D) a pencil

Step-by-step explanation:

i know the anwer is pencil because grams weigh very little  

if can plz mark brainliest

The answer is D grams is small and pencils it the smallest out of all your options

Angular velocity = w = 16 revolutions per minute

w = 16 x 2π radians per minute = 32π radians per minute

Linear velocity = v = 240π inches per minute

Since the particle is moving in a circle along the fixed point(the center of the circle), the distance between the particle and the fixed point will be the radius(r) of the circle.

v = r w
r = v/w

So,

r = 240π/32π inches = 7.5 inches

Thus the distance from the fixed point to the particle is 7.5 inches. 

So, option B is the correct answer.
