Scientific inquiry refers to an activity of a certain person in where he or she needs to study a certain thing to be able to get knowledge and understand the scientific ideas of it on how scientists study it.
Here are the 6 process that are usually involved:
=> asking questions
=> Doing research
=> Make a Hypothesis
=> Testing the hypothesis through experiments
=> analyzing the data and draw a conclusion
=> show your result.</span>

Glycerin at a temperature of 30 degrees celcius flows at a rate of 8×10−6m3/sthrougha horizontal tube with a 30mmdiameter. what

marusya05 [52]

The pressure drop in pascal is 3.824*10^4 Pascals.

To find the answer, we need to know about the Poiseuille's formula.

<h3>How to find the pressure drop in pascal?</h3>

We have the Poiseuille's formula,

$Q=\frac{\pi r^4P}{8\beta l}$

where, Q is the rate of flow, P is the pressure drop, r is the radius of the pipe, is the coefficient of viscosity (0.95Pas-s for Glycerin) and l being the length of the tube.

By substituting values and rearranging we will get the pressure drop as,

$P=3.284Pascals$

Thus, we can conclude that, the pressure drop in pascal is 3.824*10^4.

How much current must be applied across a 60 Ω light bulb filament in order for it to consume 55 W of power? Unserious answers w

sergij07 [2.7K]

Answer: current I = 0.96 Ampere

Explanation:

Given that the

Resistance R = 60 Ω

Power = 55 W

Power is the product of current and voltage. That is

P = IV ...... (1)

But voltage V = IR. From ohms law.

Substitutes V in equation (1) power is now

P = I^2R

Substitute the above parameters into the formula to get current I

55 = 60 × I^2

Make I^2 the subject of formula

I^2 = 55/60

I^2 = 0.92

I = sqr(0.92)

I = 0.957 A

Therefore, 0.96 A current must be applied.

How does visible light interact with objects to produce the colors we see?

Kipish [7]

Answer:

Visible light when all put together is white. When objects appear to be, lets say, red, it would be the only color not absorbed by that object. same goes with all other colors. So black objects absorb all colors (not 100%) and that is why black clothing gets hotter, it simply absorbs all incoming light, as apposed to white that will reflect the colors back, making all of them together appear white. Hope this helps, not the best at explaining things.

Which of the following quantities represent mass?

lisabon 2012 [21]

Answer:

Explanation:

a ) 12.0 lbs - mass

b ) .34 g - mass

c ) 120 kg - mass

As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .

d ) 1600 kN It represents force because kN or kilonewton is unit of force .

e ) it represents , length or distance because m or metre is unit of length .
