Answer:
The ball will hit the ground in 2.73 s
Explanation:
Hi there!
f(t) is the height of the ball at time "t". We need to find the value of "t" for which f(t) = 0.
f(t) = 0 Then:
-16 · t² + 40 · t + 10 = 0
Solving the quadratic equation using the quadratic formula (a = -16, b = 40, c = 10):
t = -0.23 s and t = 2.72 s
Since time can´t be negative, be discard that value.
The ball will hit the ground in 2.73 s.
Have a nice day!
Answer:
At that time, she was in the southern hemisphere
Explanation:
She is witnessing the southeastern trade breeze because the cloud is passing from east to west and she is also witnessing a storm from the southeast.
Because of the Coriolis effect, which deviates the atmosphere in the left-hand side of the southern hemisphere and generates a southeastern wind, this wind did not blow directly from south to east.
The answer is Energy
Explanation: in sound waves , energy is transferred through vibration of air particles or particles of a solid through which the sound travels
