Many planets are formed by a process called accretion, where chunks of material are drawn to bigger chunks of material and are s

lammed together until enough material has been gathered to produce a planet. Which of the following forces is responsible for accretion?

Your list of choices doesn't include any forces that could do the job.

The force that's typically responsible for the slamming is gravity.

A grinding wheel 0.35 m in diameter rotates at 2600 rpm .
ddd [48]

It is calculated that a)The angular velocity of the wheel is 272.13 rad/s,

b)On the edge of the grinding wheel, the linear speed is 47.62 m/s,

and c) On the edge of the grinding wheel, the acceleration is 12958.08 m/s².

Calculation of angular velocity, linear speed & acceleration:

Provided that,

the diameter of the wheel = 0.35 m

So, the radius, r = 0.35/2 = 0.175 m

As 1 revolution = 2π rad

(a)the angular velocity, ω = 2600 rpm = \frac{2600 * 2\pi }{60} rad/s

⇒ω = 272.13 rad/s

So, the angular velocity is 272.13 rad/s.

(b)The linear speed, v = r * ω

⇒v = 0.175 * 272.13

⇒v= 47.62 m/s

(c)The angular acceleration, a=\frac{v^{2} }{r}

a = \frac{(47.62)^{2} }{0.175}

⇒a = 12958.08 m/s²

Why is it important to consider experimental error in all the empirical results presented?
NemiM [27]
Because when your running any experiment there will always be an experimental error so always be ready for it so that you can correct that error in your experiment
