Answer:
10 km/hr/s
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time
For the car in this problem:
u = 0
t = 6 s
Substituting in the equation,
working...
Sound wave needs medium to travel
as energy which travels in this wave is because of transfer from one particle to another particle
If there is no medium then energy can not be transferred and sound wave will not travel
so in vacuum we can not listen sound
similarly here air is removed it means there is no medium inside the jar to travel the sound and hence we can not hear it
Option B is correct
Without air, the sound waves cannot travel to the ear.
