Phosphorus has 5 valence electrons
Something that scientists study that is cold could be liquid nitrogen!
Answer:
Change in height of the object
Explanation:
Change in height of the object
Since ,
We know potential energy can be written as mgh where
P.E. = mgh
M = mass ,
g = gravity constant
h = height
Kinetic energy can be written as 0.5 mv²
So , the Potential energy = kinetic energy
Then ,
velocity of object = √2 gh
Since g is a constant ,
Hence ,
Height of object will determine the velocity.
Answer:1. height(in.)
2. arm span (in.)
3. (30,27)
