Answer:
Answer:
Option B
Explanation:
Option B talks about how the frequency of the wave increases the shorter it's wavelengths
The internal energy increases 1.5 times
Explanation:
the internal energy of a mono atomic gas is given by E= 3/2kT
T1= 27⁰C= 27+273=300 K
T2=177⁰C= 177+273=450 K
E1= 3/2 k (300)
E2=3/2 k (450)
so E2/E1=[3/2 k (450)][3/2 k (300)]
E2/E1=450/300
E2= 1.5 E1
so the internal energy increases by a factor of 1.5
C. Echolocation
Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects.
