D= Mass over Volume or M/V
and if needed m*d = V and vise versa

mass divided by volume and u would get ur answer so m/v=d

Why is the spectrum of a star called an absorption spectrum?

ladessa [460]

It is called absorption spectrum because a gas of hydrogen will make a line spectrum and if viewed for another angle it would be between a continuum light and a emission line spectrum

What type of diagram chart in a service manual can be used to easily service an electronic circuit board with ICs?

Y_Kistochka [10]

<span>That could be letter B: flowchart. Flowchart diagrams can be used to easily service an electronic circuit board with ICs because they let you see the flow of the current as you could imagine it. You can use different shapes to further your explanation and illustration on how the electricity flows from a source, to its medium to the switches. You could also decide on flowcharts and be able to see where that decision leads you and you could also try to learn different decision methods which is basically illustrated on the chart.</span>

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
