By idea gas equation we can say

here P = pressure
V = volume
n = number of moles
R = Avagadro gas constant
T = temperature
So from above expression you can see that for constant number of moleswe can say




So finally the volume will be 43.9 L
Answer:
Magnitude of impulsive force is <u>8 N.s</u>.
Explanation:
Given:
Force acting on the puck is, 
Time interval for which the force acts is, 
We are asked to find the impulsive force.
Impulsive force acting on a body is the sudden change in the momentum of the body due to the application of a large constant force for a very small interval of time.
Here, the hockey player applies a large force of 40 N for a very short interval of time. So, the impact on the puck is measured as Impulse and is represented by 'J'.
Impulse in terms of applied force and time interval is given as:

Plug in the given values and solve for 'J'. This gives,

Therefore, the magnitude of impulsive force is 8 N.s.
Answer: The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on.
