Answer:
False
Explanation:
This statement is negates the photoelectric effect.
When an electron absorbs energy it jumps from a lower shell to a higher shell. When the electron releases energy it jumps from a higher shell to a lower shell.
The Kinetic energy of an ejected electron is
Where,
h = Planck's Constant
f = Frequency of incident photon
= Work function
So, this statement is false.
Density(rho) = m/v
(1.3)/((3.2)(17.1)(3.8))
since density is given in kg/m^3 you should convert the blocks dimensions to meters
1.3/(0.032*0.038*0.171)
plugging in these numbers would give you the density
1.3/0.000208
6250
with sigfigs= 6300kg/m^3
In the hierarchy of Organization within the universe , currently Earth placed as the 3rd Planet (after Mercury and Venus) , and the only planet that provided living organisms with enough resources to live such as water, foods, breathing air, etc.
An open series circuit is an electrical circuit in which the electric current does not circulate because the switch is open interrupting the flow of current. There must be a closed path for the current to flow through the circuit.
