Answer:
Explanation:
In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.
Kinetic energy is 1/2mv^2
m being mass
v being velocity
Answer:
Explanation:
Ne has its outside shell full of electrons; therefore, its reaction with other elements is minimal if at all. Na, the next element, has 1 more proton and 1 more electron. More importantly that added electron is in the outside shell. It can fill that shell by ADDing 7 more electrons or LOSing the one electron. Obviously, it loses the one electron and it does so with gusto which makes Na a very reaction element while Ne is not reactive at all. Now follow oobleck's instructions, add what you read to what I've written,then summarize all of it in your own words.
Answer:
pulling force
Explanation:
because the person is pulling that cart.
To develop this problem, we will apply Einstein's relationship which is in charge of the work done with the kinetic energy of the body versus the total energy of the system.
The energy can be calculated as
Here,
h = Planck's Constant
f = Frequency
Our values are given as,
Therefore the Energy is
Then,
Applying the Einstein Relation we have that
Therefore the maximum kinetic energy for an electron dislodged fromthe surface by the radiation is 7.68eV
