Question
Explain the difference between beats and interfrence.
✓
Answer
| S.No. | Beats | Interference |
| 1 | In this both the sound wave have almost the same frequencies. | In this, the frequencies of both sound waves are same. |
| 2 | At every point of medium amplitude value of time keeps changing with. | at every point of the medium value of amplitude remain constant. |
| 3 | The phase diference between waves at any point in the medium changes with time. | at each point of medium phase difference is constant |
| 4 | In beats the value of sound intensity at each point becomes heighest and lowest in alternating order with time in lives | interference the value of sound intensity at a particular point remain constant |

An adult weighing 600N raises the centre of gravity of his body by 0.25m while taking each step of 1m length in jogging. If he jogs for 6km, calculate the energy utilised by him in jogging assuming that there is no energy loss due to friction of ground and air. Assuming that the body of the adult is capable of converting 10% of energy intake in the form of food, calculate the energy equivalents of food that would be required to compensate energy utilised for jogging.
