1km=1000m=1000000mm
118km/h=118000000 mm/h
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:
Answer:
GPS Satellites.
Explanation:
You will always be able to have access to 4 of them no matter where you are on the Earth. This is useful for triangulation.
Answer:
Experimental
Explanation:
Here the dependency of pressure on the temperature is to be determined. For finding this factor we need to calculate the pressure of the object at different temperature.
The process of calculating pressure for different temperature is experimental investigation because we need to perform this experiment for finding these value. On the basis of observed values the we can conclude the dependency.
Thus, this investigation is experimental.
Answer:
Electromagnetic waves.
Explanation:
Electromagnetic waves include microwaves, X-rays, gamma rays, and light waves, it carries energy and it can travel through matter or empty space.
