C. sound waves and water waves
The pressure of the gas is 686 mmhg.
If h = 89 mm
and atmospheric pressure = 775 mmhg
Pressure of the gas = ?
We can find the pressure of the gas by finding the difference between both values.
pressure of the gas = 775 mmhg - 89 mm = 686 mmhg
When an object gets heated by a temperature ΔT energy needed, E = mcΔT
Here energy is given E = 2050 J
Mass of object = 150 g
Change in temperature ΔT = 15
= 15 K
a) Heat capacity of an object equal to the ratio of the heat added to (or removed from) an object to the resulting temperature change.
So heat capacity = E/ΔT = 2050/15 = 136.67 J/K
b) We have E = mcΔT
c = 
So object's specific heat = 911.11 J/kgK
It’s called the the magnetic field
Answer:
0.652 mA
Explanation:
According to Faraday's Law :



where ;
A = 



Induced current I = 
= 
= 
= 0.652 mA
Thus, the induced current in the loop of wire over this time = 0.652 A
