Answer:
Explanation:
from the ideal gas law we have
PV = mRT
HERE R is gas constant for dry air = 287 J K^{-1} kg^{-1}
We know by ideal gas law
for m_2
WE KNOW
PV = mRT
V, R and T are constant therefore we have
P is directly proportional to mass
According to the Can Manufacturers Institute, the energy used to make an aluminum can from recycled aluminum is 5% of the energy
used to make an aluminum can from virgin ore. In a typical year, 1.7 billion pounds of aluminum cans are recycled.

Answer:
Power of the string wave will be equal to 5.464 watt
Explanation:
We have given mass per unit length is 0.050 kg/m
Tension in the string T = 60 N
Amplitude of the wave A = 5 cm = 0.05 m
Frequency f = 8 Hz
So angular frequency
Velocity of the string wave is equal to
Power of wave propagation is equal to
So power of the wave will be equal to 5.464 watt
