Answer:
Required heat Q = 11,978 KJ
Explanation:
Given:
Mass = 5.3 kg
Latent heat of vaporization of water = 2,260 KJ / KG
Find:
Required heat Q
Computation:
Required heat Q = Mass x Latent heat of vaporization of water
Required heat Q = 5.3 x 2260
Required heat Q = 11,978 KJ
Required heat Q = 12,000 KJ (Approx.)
1 watt = 1 joule per second
1 joule = 1 newton-meter
1 newton = 1 kg-meter per second²
Put it all together and you have . . .
1 watt = 1 <em>kg-meter² / second³
</em>
Answer:
Explanation:
<u>Given:</u>
- Initial temperature,
- Final temperature,
- Diameter of the hole,
- Expansion coefficient of the Aluminum,
Let the diameter of the rivet at 
be 
, such that,
is the elongation in the diameter of the rivet.
We know, The change in the diameter of the rivet is related with the change in temperature as:
where, 
is the change in temperature = 
Also, 
Using these values,
It is the required diameter of the rivet at 
.
For the majority of instruments f = n f0 where f is the resonating frequency, n is any whole number and f0 is the fundamental.
<span>This applies to trumpets, violins, flutes and a broad range. </span>
<span>In such a </span>case<span> the first harmonic would be at n=1 and the second harmonic would be at n=2 </span>
<span>which gives a frequency of 84 Hz</span>
