The shape of a portion directly determines it's function.
Answer:
20 Joules
Explanation:
Mechanical Energy is the sum of kinetic and potential energy.
Since energy can only be transferred and cannot be lost, kinetic energy=potential energy.
Now we only need to use one of the formulas to find the answer. In this answer I'll be using the formula for potential energy which is mass × gravitational field strength ×height.
Substitute the values in and using gfs=10, the answer will be 20J.
Answer:
The first room is correct.
Explanation:
The higher the temerature the more air molecules it contains.
Answer:
A. elements of the same kind with different numbers of neutrons
Explanation:
As we know that an atom is represented by
here we know that
z = atomic number
A = atomic number + number of neutrons
now if the number of neutrons in an atom is different but having same number atomic number then the combination of such group of atoms is known as isotopes.
So here we have
so above is the example of isotopes
