Answer:
Acceleration is :
a = 2.89 m/s2
Explanation:
Acceleration : It is the change in the velocity of the object per unit time.
The object starts from the rest , so the initial velocity of the object is zero.
Initial velocity , u = 0
Final velocity = 100 km/h
Change the velocity to m/s because[ time unit is in second(9.60 s)]
1 km = 1000 m
1 hour = 60 x 60 sec = 3600 sec




v = 27.78 m/s
u = 0 m/s
time = 9.60 s
The acceleration"a" is calculated using :




Answer:
Extinction
Explanation:
When a species becomes extinct, every last specimen has died out
transverse wave
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
Answer: New pressure inside the flask would be 148.8 kPa.
Explanation: The combined gas law equation is given by:

As the flask is a closed flask, so the volume remains constant. Temperature is constant also.
So, the relation between pressure and number of moles becomes



- Final conditions: When additional 3 puffs of air is added

Putting the values, in above equation, we get
