Answer:
1.69515 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration

The distance between the traffic and the car after braking is 120-64.06 = 55.94 m
Time = Distance / Speed

The reaction time cannot be more than 1.69515 seconds
Water freezes at the freezing point to ice then melts to the melting turning it to liquid and vapor causing gas in precipitation
Answer:
I think is 2.
Explanation:
(The entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light)
Answer:
The lowest possible frequency of sound is 971.4 Hz.
Explanation:
Given that,
Distance between loudspeakers = 2.00 m
Height = 5.50 m
Sound speed = 340 m/s
We need to calculate the distance
Using Pythagorean theorem




We need to calculate the path difference
Using formula of path difference

Put the value into the formula


We need to calculate the lowest possible frequency of sound
Using formula of frequency

Put the value into the formula


Hence, The lowest possible frequency of sound is 971.4 Hz.
