answer:
2.5 m/s²
Explanation:
120 km/h = 120 ÷ 3.6 = 100/3 ≈ 33 m/s
a = (v2 - v1)/∆t = (33m/s - 0)/ 13s = 33/13 m/s²≈ 2.5 m/s²
That is false the part of the electromagnetic spectrum that you can see is visible light
I think the answer is 8.2 mm
Answer: 343meters away
Explanation:
The velocity of sound in air is approx 343m/s
SO,
Velocity = distance/time taken.
The time taken is 1second only.
Distance = velocity × time
Distance = 343 × 1 = 343meters.
