8 0

Answer:

1/5 km/min

Explanation:

the formula for velocity is distance/time

so if i plug in the distance and time i get 5/25 or 1/5

Hope this helps!

A slug traveling at 3 mm/h, East decided to race the slug next to him increasing his velocity to 5 mm/h, East in one hour. What

N76 [4]

The Acceleration of slug would be 2 mm/hr²

<u> Step by step Explanation:</u>

Given of the solution

Initial velocity of the slug,(we can represent as $v_{i}$ ) $v_{i}$ = 3 mm/hr

Final velocity of the slug,(we can represent as $v_{f}$ ) $v_{f}$ = 5 mm/hr

Time, t = 1 hr

Acceleration, a = ?

We know,

$a = \frac{(5-3)}{1} \\\\a = 2 mm/hr^2$

Therefore, The Acceleration of slug would be 2 mm/hr²

A 30kg uniform solid cylinder has a radius of 0.18m. if the cylinder accelerates at 0.023 rad/s^2 as it rotates about an axis th

Nuetrik [128]

Answer:

0.011 N-m

Explanation:

Given that

The mass of a solid cylinder, m = 30 kg

The radius of the cylinder, r = 0.18 m

The acceleration of the cylinder, $\alpha =0.023\ rad/s^2$

It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :

$\tau=I\alpha$

Where

I is the moment of inertia of the cylinder,

For cylinder,

$I=\dfrac{mr^2}{2}$

So,

$\tau=\dfrac{mr^2\alpha }{2}\\\\\tau=\dfrac{30\times (0.18)^2\times 0.023 }{2}\\\\\tau=0.011\ N-m$

So, the required torque on the cylinder is 0.011 N-m.

Which statement about solubility is true?

NISA [10]

Answer to your question is B. I did a science lab over this...
Test was to see which would dissolve fastest... A tablet in warm water... and a tablet in cold water....

And this question isn't asking for solids or gasses.... because something dissolves with a liquid :P thanks...
