To answer this question, we must use the equation for the volumetric expansion of gases at constant pressure. This equation is given by:

We know:
is the initial volume
ΔT is the temperature change = 45 ° -20 ° = 25 °
is the coefficient of gas expansion and is equal to 1/273
Then the final volume of the gas is:


Answer:
= 15 m/s
Explanation:
Considering right side(west) as positive x-axis and south as negative y-axis.
velocity of boat in still water 
velocity of stream 
now relative velocity of boat w.r.t. stream 
this velocity with which ac distance will be covered.
therefore magnitude of 
= 15 m/s
Explanation:
Se supone que si es 5.31 x 7.6 los límites son 38.98 ahora si fuera en suma mueves los puntos dos veces a la izquierda la sumatoria seria la siguiente .00531 + .0076 la respuesta seria
.00607
