Answer:
Work done = 600 J
Power used = 60 W
Explanation:
Given:
Force acting on the box is,
Displacement of the box is,
Time taken for the work,
Now, we know that, work is said to be done by a force only when there is displacement caused by the force in its direction.
Here, the force acting on the box causes a displacement of 30 m in its direction. So, work done is equal to the product of force and displacement caused.
Therefore, work done on the box is given as:
Therefore, the work done is 600 J.
Now, we know that, power is given as work done per unit time.
So, power used is given as:
Therefore, the power used is 60 W.
Answer:
Explanation:
Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.
The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.
