The answer to the question is 1.5708~1.571.
Answer:
11.6 g/m³
Explanation:
The complete question is,
The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air at this temperature is 20 gram/cubic meter? a device showing that at 22 degrees celsius the relative humidity is 58%.
Solution:
saturation of water in air is showed by the relative humidity. As it is 58% and not 100%. Lets scale density that we have, if humidity is 100%.
density is 20 gram/m³ when the humidity is 100%
When humidity is 58%
0.58 x 20 = 11.6 g/m³
Therefore, density is 11.6g/m³
Answer:
This is a PERT (Program Evaluation and Review Technique) question and the expected duration of completing this activity can be solved using the formula below.
Pert Expected Duration Estimate = ║Optimistic Duration + (4 x Most Likely Duration) + Pessimistic Duration║/6.
15 days = Most likely Activity Duration.
10 days = Optimistic Activity Duration
20 days = Pessimistic Activity Duration
Substituting these values, we will have
(10 +(4 X 15) +20)/6. The pert estimate is therefore calculated as 15 days
The expected duration of completing this activity = 15 days.
B. The initial velocity has components both parallel and perpendicular to the magnetic field.
Explanation:
When a charged particle moves in a magnetic field, it experiences a force which is given by
where
q is the charge
v is the velocity of the particle
B is the strength of the magnetic field
is the angle between the directions of v and B
From this formula, it is clear that the force has only a component in the direction perpendicular to direction of the the motion of the particle. Therefore:
- if the initial velocity is perpendicular to the magnetic field, then the particle will follow a perfectly circular path
- If the initial velocity is parallel to the magnetic field, then the particle will continue moving straight, since it will experience no force
- If the initial velocity has components both parallel and perpendicular to the magnetic field, then it will move in a helical or spiral path, which is a composition of the two motions above (straight motion + circular motion)
Answer:
the weight of the large stone is greater than a small one
Explanation:
because the large stone has greater mass then the small stone.therefore it is difficult to lift the large stone on the surface of the earth but easy to lift the small one
