Answer:

Option B: the period during which a solid is not changing state; its temperature is increasing

Explanation:

The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)

Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.

Yuri [45]

Answer:

Average speed = (2x+3y)/5 miles/hour

Explanation:

Average speed is the total distance travelled per unit time.

Average speed = total distance/total time taken

Given;

1. Travelled x miles per hour for 2hours.

2 travelled y miles per hour for 3 hours.

Distance covered is;

1. Distance = speed × time

d1 = x × 2 = 2x

2. d2 = y × 3 = 3y

Total distance travelled = d1+d2 = 2x + 3y

Total time taken = t1+t2 = 2+3 = 5hours

Average speed = (2x+3y)/5 miles/hour

Airida [17]

Answer:

\frac{I}{I_0}=113.68

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

P=IA\\\Rightarrow I=\frac{P}{A}\\\Rightarrow I=\frac{63\times 10^{-6}}{4\times \pi \times 210^2}

Threshold intensity = I_0=1\times 10^{-12}\ W/m^2

Ratio

\frac{I}{I_0}=\frac{\frac{63\times 10^{-6}}{4\times \pi \times 210^2}}{1\times 10^{-12}}\\\Rightarrow \frac{I}{I_0}=113.68

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68
