50. The atomic mass is essentially a tally of all of the atoms in the nucleus, since electrons are essentially negligible in mass.
Answer:
The stored energy is .
Explanation:
Given that,
One side of square plates = 8.5 cm
Distance = 2.5 mm
Charge = 14 nC
We need to calculate the energy stored
The energy is stored by the electric field between two square plates is defined as,
We calculate the area iof square plates
Now, put the value into the formula
Hence, The stored energy is .
The answer is:
-when Jackhammer is a huge hammer used to breaking up the hard rocks and the hard materials to smaller pieces.
-and the metamorphic rocks are type of rocks which change to metamorphic rock by heating and high pressure so, the chemical and physical properties of the rock will be changed.
-and here in cause of using the Jackhammer there is no change in the chemical or physical properties of the original rock and no high temp(more than 200°C ) or high pressure to change to metamorphic rock . It is just a breaking up of the rock to small parts.
