A container of mass 200kg contains 160cm

Physics
1 answer:
Zepler [3.9K]3 years ago
7 0

Answer:

mass of liquid = total mass - mass of container

m = 52000kg - 200kg

m = 519800

D = m/v

D = 519800/160

D = 3,248.75 kgm-³

In a real hemoglobin molecule, the tendency of oxygen to bind to a heme site increases as the other three heme sites become occu
sasho [114]
Since there are four states, then the grand partition function of the system is

Z = 1+2 e^{(0.55eV+ \alpha )/kT} +e^{(1.3eV+ 2\alpha )/kT}

where α is the chemical potential

Then, the occupancy of the system is

bar \ n=(e^{(0.55eV+ \alpha )/kT} +e^{(1.3eV+ 2\alpha )/kT})/Z

Then using this equation, \alpha =-kT(V Z_{int} /N v_{Q}) and approximating Z_int to be kT/0.00018 eV, the model would look as that attached in the figure. That is the occupancy vs. pressure graph. 

There are more occupancies when the oxygen is high (high pressure) especially in the lungs. Heme sites tend to be occupied by oxygen.

What happens when you modify a pwc's exhaust system?
Rasek [7]
PWC stands for Personal WaterCraft.
When you modify a PWC's exhaust system it may raise noise to an illegal level.
<span>That's why, you should avoid maneuvers that cause the engine exhaust to lift out of the water. </span>The noise can be irritant to people, so avoid making excessive noise near residential and camping areas.

The drawing shows a bicycle wheel resting against a small step whose height is h = 0.110 m. The weight and radius of the wheel a
Pavel [41]

Answer:

F=27.39N

Explanation:

Take sum of torques at the point the step touches the wheel, that eliminates two torques

ΣT=T_{N}+T_{f}+T_{W}

Since we are looking for when the wheel just starts to rise up N-> 0 so no torque due to normal force

T_{N}=0

The perpendicular lever arm for the F force is R-h

T_{f}=F*(r-h)

And the T of gravity according to the image

T_{W}=W*(\sqrt{r^2-(r-h)^2}

ΣT=0

T_{N}+T_{f}+T_{W}=0

F*(r-h)+W*(\sqrt{r^2-(r-h)^2}=0

F=\frac{W*(\sqrt{r^2-(r-h)^2}}{r-h}

F=\frac{24.9 N*(\sqrt{0.336^2-(0.336-0.110)^2}}{(0.336-0.11)}

F=27.39N

Give an example in which a small force exerts a large torque. give another example in which a large force exerts a small torque.
goldenfox [79]
<span>Since the torque involves the product of force times lever arm, a small force can exert a greater torque than a larger force if the small force has a large enough lever arm.

With a large force exerts a small torque is a gate, hinged in its vertical line (axis). When pushed from a point near to the hinge, a very large amount is needed to open the gate.
