Answer:
As a result, light travels fastest in empty space, and travels slowest in solids. In glass, for example, light travels about 197,000 km/s.
Explanation:
Answer:
a bowling ball because it has the most mass.
Answer:
atm
Explanation:
The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column
Thus, 
Substituting the given values, we get -
kg/m3
m/s^2
meters
atm
Answer:
The kinetic energy is 
Explanation:
From the question we are told that
The potential difference is 
The potential energy of the end is mathematically represented as

q is the charge on an electron with a constant value of 
substituting values


Now from the law of energy conservation
The 
Where
is the potential energy at the end
So

The negative sign is not includes because kinetic energy can not be negative
