Iron atoms are heavier than gold atoms
Explanation:
Chart:
Materials Specific heat
Gold 0.129
Iron 0.45
The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1K.
We can see that the more the mass of a substance, the higher the specific heat needed to raise the temperature.
Specific heat is directly proportional to the mass of substance.
It also dependent on the amount of heat supplied and the nature of the substance.
- The mass of a body is the amount of substance it contains.
- A heavier substance has more number of atoms in it.
- Since iron has a higher specific it, the atoms must be heavier or more than that of gold.

Answer:
-3.396 m/s or 3.465 m/s
Explanation:
v = Speed of sound in air = 343 m/s
= Relative speed of the singer
f = Observed frequency
f' = Actual frequency
1% change can mean 
From the Doppler effect equation we have
The velocity is -3.396 m/s
when 
The velocity is 3.465 m/s
It can be transmit in hydraulic machine, exerting a small cross-sectional area can lead to pressure being transmitted
