Answer:
It can either be food, mating, or competition with other organisms for resources.
Answer:
Explanation:
Given that,
The speed of an electron,
We need to find the wavelength of this electron. It can be calculated using De -broglie wavelength concept as :
h is the Planck's constant
So, the wavelength of the electron is . Hence, this is the required solution.
Answer:
Explanation:
Given data
To find absolute pressure of air in the tank.We must find the pressure athe parallel point from the right tube
So
Given that,
The radius of a flywheel, r = 20 cm = 0.2 m
The centripetal acceleration experienced on the edge of the flywheel = 900 cm/s² = 9 m/s²
To find,
The speed of a point on the edge.
Solution,
The formula for the centripetal acceleration is given by :
Hence, the required speed is 1.34 m/s
<span>The element with the greatest number of known stable isotopes is tin, with 10 stable isotopes. Including unstable isotopes, mercury, cesium, and barium are each known to have 40 isotopes. Theory predicts however that many unstable isotopes should exist which have not yet been discovered (especially on the neutron-rich side of the line of stability.)
