Explanation:
classical physics and modern physics.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
The new speed of the aircraft is equal to 774.61 mph north of east.
Why?
To calculate the new speed, we first need to know the horizontal component of the wind's speed (moving to the east) since the jet is moving to the east.
We can use the following formulas to solve the problem:
We are given the following information:
So, substituting and calculating we have:
For the vertical speed, we have:
Now, to calculate the airplane speed , we can use the following equation (Pytagorean Theorem):
Hence, we have that the new speed is equal to 774.61 mph north of east.
Have a nice day!
Answer:
120 km/s
Explanation:
Given data :
Radius of the star is r = 19 km
Rotational time period of the star is T = 1 s
Therefore, we know that the velocity of the star is given by :
V = 119380.52 m/s
Therefore, the velocity of the point on the equator of the star is = 120 km/s
Answer:Due to the pressure difference created by rotating fans.
Explanation:
In most of the vacuum cleaners, there is an area which is of disc shape and it is in right next to the motor. There are several fans within the disc that spin at a very high velocity.
The blades will push the air outside of the disk.There is no air in inside of the disc and air pressure creates which pushes air inside the disk to replace the missing air.
So motor is pushing the air outside and to maintain this pressure the air is pushing toward inside with dirt.
