Atomic mass (z) - atomic number / # of protons (n) = # of neutrons:
151-54=97
You can easily tell what element X is. With an atomic number of 54, the element is the noble gas Xenon (Xe).
Answer:
Water leaves the sprinkler at a speed of 2.322 m/sec
Explanation:
We have given internal diameter of the garden
Speed of water in the hose is
Number of holes n = 22
Diameter of each holes
According to continuity equation
So water leaves the sprinkler at a speed of 2.322 m/sec
Answer:
The position of the spring in terms of g, m & k is
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒
This is the position of the spring in terms of g, m & k.
Because they’re far from each other and the J0523 has lower mass then the UY which is a red dwarf.
