Answer:

Dr. Nagyvary suggests that the soaking and finishing process have become the two key factors that produce the distinctive sound of a stradivari violins.

Explanation:

Dr. Nagyvary suggests that the soaking and finishing process have become the two key factors that produce the distinctive sound of a stradivari violins. Due to the fact that timber was initially transported by floating or rolling down by a river and deposited in sea water, the soaking process can eliminate additives from the wood which made it noisy.

Dr. Nagyvary also conducted an experiment and observed that microbes and minerals seeped the wood and contributed to unique sound of violins.

hichkok12 [17]

Answer:

ΔT= 11.94 °C

Explanation:

Given that

mass of water = 10 kh

Time t= 15 min

Heat lot from water = 400 KJ

Heat input to the water = 1 KW

Heat input the water= 1 x 15 x 60

=900 KJ

By heat balancing

Heat supply - heat rejected = Heat gain by water

As we know that heat capacity of water

$C_p=4.187 \frac{KJ}{kg-K}$

$Q=mC_p\Delta T$

Now by putting the values

900 - 400 = 10 x 4.187 x ΔT

So rise in temperature of water ΔT= 11.94 °C

Answer:

a) 70.29 %

b) 37%

Explanation:

percent reduction can be found from:

PR = 100*(π(do/2)^2-π(df/2)^2)/π(do/2)^2

= 100*(π(11.34/2)^2-π(6.21/2)^2)/π(11.34/2)^2

=70.29 %

percent elongation can be found from:

EL =L_f - Lo/Lo*100

= (73.17 -53.3/53.3)*100

= 37%
