Answer:
Mass of second object will be 15 kg
Explanation:
We have given mass of first object = 12 kg
Acceleration
According to second law of motion we know that force F = MA
So force
As the same force is applied to the second object of acceleration
So force = ma
m = 15 kg
So mass of second object will be 15 kg
Answer:
Explanation:
According to the law of conservation of energy, the total energy of the system can be expresed as the sum of the potential energy and kinetic energy:
When the spring is in its equilibrium position, that is , the object speed its maximum. So, we have:
In order to double its maximum speed, that is . We have:
As we know that with respect to oxygen atom taken as reference the product of atomic mass and specific heat of a metal will remain constant.
this product is equal to 0.38
so here we will say that let atomic mass of the metal is M
so with respect to oxygen atom its mass is given as
now we will have
now we will have
so atomic mass of the metal is 7 g/mol
