Answer:
Mass will be the same
Explanation:
Mass does not change with gravity .... WEIGHT will be different, but not mass.
<span>Here I think you have to find the velocity in x and y components where x is east and y is north
So as air speed indicator shows the negative speed in y component and adding it in
air speed while multiplying with the direction component we will get the velocity as velocity is a vector quantity so direction is also required
v=-28 m/s y + 18 m/s (- x/sqrt(2) - y/sqrt(2))
solving
v= -12.7 m/s x-40.7 m/s y
if magnitude of velocity or speed is required then
speed= sqrt(12.7^2 + 40.7^2)
speed= 42.63 m/s
if angle is asked
angle = arctan (40.7/12.7)
angle = 72.67 degrees south of west</span>
Answer:
1) 2726.5 J/K 2) decrease 3) 0
Explanation:
1)
change in entropy is given by 
here Q=mL where L is the latent heat of vaporization. therefore
2) 
since the heat is taken from surroundings, the change in entropy is negative therefore entropy of surrounding will decrease.
3) since there is no heat exchange with universe therefore , Q=0 in this case
