A machine gun fires 10 rounds per second. The speed of the bullets is 300m/s.

9.What is the distance in the air between the flying bullets?

time between shots: 1/10 sec

distance=300m/s*.1s=30m

It's 3000000 mm

It's not 30m it's 3000cm

To calculate the distance in the air between the flying bullets, we need to determine the time it takes for each bullet to be fired and find the distance traveled during that time.

Given information:
- The machine gun fires 10 rounds per second.
- The speed of the bullets is 300 m/s.

Step 1: Calculate the time it takes for each bullet to be fired.
Since the machine gun fires 10 rounds per second, the time interval between each bullet being fired is 1/10th of a second (0.1 seconds). This means that every 0.1 seconds, a bullet is fired.

Step 2: Determine the distance traveled by each bullet during that time.
The distance traveled by a bullet is given by the formula: Distance = Speed × Time

Using this formula, we calculate the distance traveled by each bullet:
Distance = 300 m/s × 0.1 seconds
Distance = 30 meters

Therefore, the distance in the air between each flying bullet is 30 meters.
