Answer:

Explanation:

This question seeks to test the knowledge of operating a micropipette.

When trying to draw a liquid from a container using a micropipette (tip), the micropipette should be <u>held vertically straight at an angle of 90 degrees</u> with the plunger pushed to the <u>first resistance</u> and then released.

When trying to dispense the drawn liquid into another container, the micropipette is <u>held vertically straight at the same 90 degrees</u> but the plunger is pushed to the <u>second/last</u> point of resistance. <u>You keep pressing</u> the plunger at the same degree and resistance until dispensing is done.

Why do ions stick together?
melisa1 [442]

Answer:

The ions stick together because of the electrostatic attraction between ions that are near one another.Electrostatic attraction refers to the electrostatic force of long-range interaction occurring between the attractive electrostatic adsorption in aqueous solution with differently charged particles or uncharged particles.

Hope this helps!! ;)

Ted wants to hang a wall clock on the wall by using a string. If the mass of the wall clock is 0. 250 kilograms, what should be
antoniya [11.8K]
Sum of all forces = mass * acceleration

Ft= tension force
Fw= force of gravity (Fw= mass* acceleration of gravity which is 9.8 this only applies to force of gravity)

Ft- Fw = 0 (there is no acceleration)
Ft = Fw
Ft= m*g
Ft= 0.250kg*9.8m/s
Ft= 2.45N

Your mother is sure that you were driving too fast because she knows
photoshop1234 [79]
She knows the speed limit in the area, and also saw the speed you were going on the speedometer. The speed you were going was faster than the limit allowed, so that's how she knew you were going too fast.

The apparent height of a building 10.5 km away is 0.02 radians. What is the approximate height of the building to the nearest me
Ksenya-84 [330]

Answer:

Approximate height of the building is 23213 meters.

Explanation:

Let the height of the building be represented by h.

0.02 radians = 0.02 × \frac{180^{o} }{\pi }

                     = 0.02 x (180/\frac{22}{7})

0.02 radians  = 1.146°

10.5 km = 10500 m

Applying the trigonometric function, we have;

Tan θ = \frac{opposite}{adjacent}

So that,

Tan 1.146° = \frac{h}{10500}

⇒ h = Tan 1.146° x 10500

      = 2.21074 x 10500

      = 23212.77

h = 23213 m

The approximate height of the building is 23213 m.
