You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30°C to
olasank [31]
<h3><u>Answer;</u></h3>

C. 352.6 m/s

<h3><u>Explanation;</u></h3>

Velocity of sound is dependent on temperature. An increase in temperature, increases the velocity of sound.

To calculate the velocity of the sound wave, we use this formula:

V = 331 + [0.6*T]; Where V is the velocity and T represents temperature.

When the temperature is 36 degree Celsius, we have 

V = 331 + [0.6 * 36]

V = 331 + 21.6 = 352.6 

Therefore,

 V = 352.6 m/s.

Ava threw a hamster at her sister the other day she used 12N of force to accelerate the hamster at 8m/s2.what was the mass of th
xenn [34]

<u>We are given:</u>

The force applied on the poor hamster (F) = 12 N

Acceleration of the poor Hamster (a) = 8 m/s²

<u>Solving for the mass of the Poor Hamster:</u>

From newton's second equation of motion, we know that:

F = ma

<em>replacing the given values</em>

12 = 8 * m

m = 12/8 kg

m = 3/2 kg

The poor Hamster weighs 3/2 kg
