Answer:
Warming up may help reduce muscle soreness and lessen your risk of injury. Cooling down after your workout allows for a gradual recovery of preexercise heart rate and blood pressure.
Explanation:
Answer:
To convert inches to centimeters, use an easy formula and multiply the length by the conversion ratio.
Since one inch is equal to 2.54 centimeters, this is the inches to cm formula to conver
Explanation:
Answer:
a) D=-4273(x)-2327(y)
b) v=23.33m/s
c) V=-13.51m/s south of west.
Explanation:
In order to find the displacement we have to divide the motion on its X and Y components:
The total X displacement is the algebaric sum of the movement:
We have to do the same on Y:
D=-4273(x)-2327(y)
The angle is given by:
That is 28.57 degrees south of west.
the total displacement magnitude is given by:
The average speed is given by:
and the Average velocity is given by:
The average velocity is:
with an angle of 28.57 degrees south of west.
Sound intensity of 1 baby, I = 8*10^-8 W/m^2
The sound heard should be higher by:
10*log (n) where for 5 babies, n = 5. Then
10*log (n) = 10*log (5) ≈ 7 dB
Also give is the reference sound, Io = 1.0*10^-12 W/m^2
Therefore,
Sound intensity, L1 = 10*log (I/I1) = 10*log [(8*10^-8)/(1*10^-12)] ≈ 49 dB
Therefore, total intensity for the five babies is:
Total intensity = 49+7 = 56 dB
