Answer:
3.2 miles
Explanation:
We can assume that the light coming from the lightning reach instantaneously our eyes (because light travels very fast, 
), so the time between the lightining and the hearing of the thunder is equal to the time that sound takes to each us.
Sound travels in air approximately at speed
v = 343 m/s
So the distance it covers in a time of t = 15 seconds is
And using the conversion from meters to miles,
1 mile = 1609 meters
we find
Answer:
c) proportional to the square of the amount the spring that is stretched from its equilibrium length
Explanation:
according to Hooke's law, the elastic potential energy of a spring is:
where:
K is the spring constant
x is the distance that the spring's is compressed.
as you can notice the distance is squared, so the energy is proportional to the square of the compressed distance.
To solve this exercise,
the following speed equation must be applied:
V = d / t (mi/hr)
V: speed (mi/hr)
d: distance (mi)
t: time (s)
We know the distance (d= 5 miles) and the time (t= 0.2 hours), so
we proceed to replace these values in the formula to calculate the lion’s speed:
V = d / t
V = 5 mi/0.2 hr
V = 25 mi/hr
The lion’s speed is 25
mi/hr, so the last option is the right answer
Input= ?
Output= 0.75
MA= 0.33
So I just kept on Dividing numbers until I was close to "0.33" & I cam up with the answer of .......... 0.25.
So when you divide 0.25 by 0.75 you get the MA of 0.33
1. 12m/s and here’s how. The equation for calculating velocity of a wave is lambda x frequency. So 2m x 6Hz. Hz can be 1/s so the only unit of measurement we get is meters and seconds. So the answer will be 12m/s.
2. Frequency=2Hz period= 0.5 seconds
Equation for frequency is velocity/wavelength. 10m/s divides by 5m = 2Hz.
Equation for period is 1 / frequency. 1 divided by 2 = 0.5 seconds
3. The answer is the picture of you can’t read my hand writing comment and say “ I need the info about the wave because I can’t read your hand writing “ thank you and I hoped I helped
