The electromagnetic wave shown above is made up of vibrating Electric fields.
I assume this is why electromagnetic waves can travel through a vacuum, due to lack of matter.
Answer:
true
Explanation:
i've read about it in a bunch of different articles and stuff
Answer:
12.5752053801 m/s
No.
Explanation:
Q = Volume flow rate =
d = Diameter of pipe = 9 cm
A = Area =
Volume flow rate is given by
Velocity of fluid is 12.5752053801 m/s
The volume flow rate in m³/s is
The flow of fluid does not depend on the type of water used. Hence the answers would be same. If Q is constant v will be the same irrespective of the type of water used.
Are there any option i could choose ?
Answer:
Explanation:
Let suppose that centrifuge is rotating at constant angular speed, which means that resultant acceleration is equal to radial acceleration at given radius, whose formula is:
Where:
- Angular speed, measured in radians per second.
- Radius of rotation, measured in meters.
The angular speed is first determined:
Where is the angular speed, measured in revolutions per minute.
If , the angular speed measured in radians per second is:
Now, if and , the resultant acceleration is then:
If gravitational acceleration is equal to 9.807 meters per square second, then the radial acceleration is equivalent to 1006.382 times the gravitational acceleration. That is:
