Which of the following had have the highest viscosity ?

2 answers:

5 0

Hello There

Answer: Corn Syrup (B)

Reason: Corn syrup has high viscosity because it is made out of corn which is mixed with acidic water, which is then mixed with enzymes, and then heated and pressed to get the liquid from the corn,

I hope this helps

Two point charges, with charge magnitudes q and ????, are placed a distance r apart. In this arrangement, each point charge expe

sammy [17]

Answer:

1) Q ’= 8 Q , 2) q ’= 16 q , 3) r ’= ¾ r

Explanation:

For this exercise we will use Coulomb's law

F = k q Q / r²

It asks us to calculate the change of any of the parameters so that the force is always F

Original values

q, Q, r

Scenario 1

q ’= 2q

r ’= 4r

F = k q ’Q’ / r’²

we substitute

F = k 2q Q ’/ (4r)²

F = k 2q Q '/ 16r²

we substitute the value of F

k q Q / r² = k q Q '/ 8r²

Q ’= 8 Q

Scenario 2

Q ’= Q

r ’= 4r

we substitute

F = k q ’Q / 16r²

k q Q / r² = k q’ Q / 16 r²

q ’= 16 q

Scenario 3

q ’= 3/2 q

Q ’= ⅜ Q

we substitute

k q Q r² = k (3/2 q) (⅜ Q) / r’²

r’² = 9/16 r²

r ’= ¾ r

A vessel containing 200 ml hydrogen gas at pressure 500torr at temperature 10 degree C.Find its volume when pressure increased t

Margaret [11]

Answer:

When the pressure and the temperature are increased the volume is 285.7 ml.

Explanation:

We can find the new volume by using the Ideal Gas Law:

$PV = nRT$

Where:

P: is the pressure

V: is the volume

n: is the number of moles

R: is the gas constant

T: is the temperature

Initially, when V₁ = 200 ml, P₁ = 500 torr and T₁ = 10 °C, we have:

$nR = \frac{P_{1}V_{1}}{T_{1}}$ (1)

And finally, when P₂ = 700 torr and T₂ = 20 °C, we have:

$nR = \frac{P_{2}V_{2}}{T_{2}}$ (2)

By equating (1) with (2):

$\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}$

$V_{2} = \frac{P_{1}V_{1}T_{2}}{T_{1}P_{2}} = \frac{500 torr*200 ml*20 ^{\circ} C}{10 ^{\circ} C*700 torr} = 285.7 ml$

Therefore, when the pressure and the temperature are increased the volume is 285.7 ml.

I hope it helps you!

A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 with the horizontal. The rope moves paralle

MaRussiya [10]

Answer

given,

angle with horizontal = 12°

constant speed with the slope = 1 m/s

Work on the skier to move 8 m = 900 J

a) Rope moved with constant speed

change in kinetic energy is equal to zero

work done by the force of the rope = 900 J

rate of force of the rope when skier move with

b) v = 1 m/s total time t = 8 s

Power = $\dfrac{work\ done}{time}$

= $\dfrac{900}{8}$

= 112.5 W

c) v = 2 m/s total time t = 8/2 = 4 s

Power = $\dfrac{work\ done}{time}$

= $\dfrac{900}{4}$

= 225 W

During normal beating, the heart creates a maximum 3.60 mV potential across 0.250 m of a person's chest, creating a 1.00 Hz elec

grandymaker [24]

Answer:

The maximum electric field strength is 0.0144 V/m.

Explanation:

Given that,

Electric potential created in the heart, V = 3.6 mV

Distance, d= 0.25 m

Frequency of the the electromagnetic wave, f = 1 Hz

We need to find the maximum electric field strength created. We know that the electric potential is given by :

$V=Ed$

E is the maximum electric field strength

$E=\dfrac{V}{d}\\\\E=\dfrac{3.6\times 10^{-3}\ V}{0.25\ m}\\\\E=0.0144\ V/m$

So, the maximum electric field strength is 0.0144 V/m. Hence, this is the required solution.
