An empty truck traveling at 10 km/h has kinetic energy. How much kinetic energy does it have when loaded so that its mass and it

Katena32 [7]

Answer:

8 time increase in K.E.

Explanation:

Consider Mass of truck = m kg and speed = v m/s then

K.E. = 1/2 ×mv²

If mass and speed both are doubled i.e let m₀ = 2m and v₀ = 2v then

(K.E.)₀ = 1/2 ×2m(2v)²

(K.E.)₀ = 8 (1/2 × mv²) = 8 × K.E.

At a distance 30 m from a jet engine, intensity of sound is 10 W/m^2. What is the intensity at a distance 180 m?

AleksandrR [38]

Answer:

$I_{2}=0.27 W/m^2$

Explanation:

Intensity is given by the expresion:

$I_{2}=Io (\frac{r1}{r2} )^{2}$

where:

Io = inicial intensity

r1= initial distance

r= final distance

$I_{2}=10 W/m^2 (\frac{30m}{180m} )^{2}$

$I_{2}=0.27 W/m^2$
