Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
Answer:
The original speed of the mess kit is 5.65 m/s.
Explanation:
Given that,
Mass of kit =7.0 kg
Mass of first = 3.5 kg
Speed= 5.5 m/s
Speed of other particle part = 7.5 m/s
Angle = 30°
We need to calculate the momentum of first part
Using formula of momentum
Put the value into the formula
We need to calculate the momentum of second part
Using formula of momentum
We need to calculate the total momentum
We need to calculate the original speed of the mess kit
Using formula of momentum
Put the value into the formula
Hence, The original speed of the mess kit is 5.65 m/s.
I think B but I would need to see how much forces are applied
Answer:
the image is virtual and erect and the lens divergent; therefore the correct answer is C
Explanation:
In a thin lens the magnification given by
m = h '/ h = - q / p
where h ’is the height of the image, h is the height of the object, q is the distance to the image and p is the distance to the object.
It indicates that the object is straight and is placed at a distance p> f
analyze the situation tells us that the magnification is positive so the distance to the image must be negative, that is, that the image is on the same side as the object.
Consequently the lens must be divergent
The magnification value is
0.4 = h ’/ h
h ’= 0.4 h
therefore the erect images
therefore the image is virtual and erect and the lens divergent; therefore the correct answer is C
Answer:
E=26779230N/C(option 5)
Explanation:
Let Lamda be charge per lenght=73*10^-6c/m
Distance r=4.9cm =0.049m
Coulomb constant k=8.98755*10^9
But electric field is 2*k*lamda/r
E=(2*8.98755*10^9*73*10^-6)/0.049
E=26779230N/C
