Answer:
2400 J
Explanation:
Latent heat: This is also called hidden heat, it is the heat that is not detectable by the thermometer.
From the question,
Q = cm.................. Equation 1
Where Q = Energy, c = specific latent heat of the liquid, m = mass of the liquid.
Given: c = 4000 J/kg, m = 600 g =( 600/1000) kg = 0.6 kg
Substitute these values into equation 1
Q = 4000×0.6
Q = 2400 J
Hence the energy required is 2400 J
Answer:
Tuning the keys.
Explanation:
<em>"Guitar strings are tuned (tightened and loosened) using their tuning keys. </em><em>Applying too much tension to a string tightly can raise it to the pitch of the next note, while loosening it can easily lower it the same amount.</em><em> Increasing the tension raises the pitch. The length of a string is also important."</em>
