If the temperature is high there is less water because it evaporates if it is cloudy it is more because it doesn't evaporate
Choice-A is the correct one. It doesn't say it, but it means he'll see the ball reach the catcher's mitt first BEFORE HE HEARS IT slap the mitt.
The answer is 3

Explanation:
Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.
After collision, blue ball travels 12 m/s.
<u>Using conservation of Linear Momentum</u> :
m1u1 + m2u2 = m1v1 + m2v2
0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12
v1 = 0 m/sec i.e. <u>Yellow ball comes to rest</u>.
