Two fans are watching a baseball game from different positions. One fan is located directly behind home plate, 18.3 mfrom the ba

hjlf

Answer:

Δt = 0.315s

Explanation:

To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:

$t_1=\frac{d_1}{v_s}$

$t_2=\frac{d_2}{v_s}$

d1: distance to the first fan = 18.3 m

d2: distance to the second fan = 127 m

vs: speed of sound = 345 m/s

You replace the values of the parameters to calculate t1 and t2:

$t_1=\frac{18.3m}{345m/s}=0.053s\\\\t_2=\frac{127m}{345m/s}=0.368s$

The difference in time will be:

$\Delta t =t_2-t_2=0.368s-0.053s=0.315s$

Hence, the time difference between hearing the sound at the location s of both fans is 0.315s

1)If I'm on an elevator that breaks loose and plummets down the shaft, can I avoid harm by jumping at the last second?

umka2103 [35]

Answer and Explanation:

1) If you were to jump at the last second, you would decrease the impact velocity by 7 mph. This is because most humans have a maximum jump velocity of 7 mph. You may still get hurt, but the damage would be significantly less than if you were to not jump.

2) Bathroom mats are made of fabrics, and fabrics absorb the moisture in the air. If you were to take a shower at any temperature, the fabric will soak up the moisture in the air, so when you touch it, it doesn't feel cold.

The tile floor, however, isn't able to store the moisture into itself. The temperature of the tile will be less than the temperature of your feet.

A) position time graph for both is shown

here one of the graph is of lesser slope which means it is moving with less speed while other have larger slope which shows larger speed

At one point they intersects which is the point where they both will meet

B) Let the two will meet after time "t"

now we can say that
