Answer:
The dynamic viscosity of the liquid is 0.727 kg/m*s
Explanation:
In the equation for that viscosimeter, ν = KR⁴t, <u>the terms K and R are not dependent on the liquid that is being tested</u>, unlike ν and t.
Using that equation and the data given in the problem, we can calculate the product of K and R⁴.
1.19*10⁻³m²/s = (KR⁴)* 1430 s
KR⁴=8,32*10⁻⁷m²/s²
We can now calculate the<em> </em><u><em>kinematic</em></u> viscosity of the unknown liquid.
ν=8,32*10⁻⁷m²/s²*900s
ν=7.49*10⁻⁴m²/s
The relationship between the <em>kinematic</em> viscosity and the <em>dynamic</em> viscosity is given by the equation μ=ν * ρ, where μ is the dynamic viscosity and ρ is the density. Thus:
μ=7.49*10⁻⁴m²/s * 970 kg/m³
μ=0.727 kg/m*s
Answer:
I think it's B but I could be wrong so really sorry if I am
Answer:
721 J
Step-by-step explanation:
At the bottom of its swing, all the potential energy of the pendulum has been converted to kinetic energy.
KE = 721 J
Answer:
A.
The moon's gravitational pull on Earth causes water to bulge on two sides of the Earth.
Endoskeleton
Pros: bones do not get broken so easily
If bones broken, can heal more quick since they are inside with good blood and nutrient supply
Cons: flesh can easily get damage
no shedding of endoskeletons, so no new skeleton cannot if injuried.
Change those up for exoskeletons.. pros for cons and cons for pros
