Answer:
741 J/kg°C
Explanation:
Given that
Initial temperature of glass, T(g) = 72° C
Specific heat capacity of glass, c(g) = 840 J/kg°C
Temperature of liquid, T(l)= 40° C
Final temperature, T(2) = 57° C
Specific heat capacity of the liquid, c(l) = ?
Using the relation
Heat gained by the liquid = Heat lost by the glass
m(l).C(l).ΔT(l) = m(g).C(g).ΔT(g)
Since their mass are the same, then
C(l)ΔT(l) = C(g)ΔT(g)
C(l) = C(g)ΔT(g) / ΔT(l)
C(l) = 840 * (72 - 57) / (57 - 40)
C(l) = 12600 / 17
C(l) = 741 J/kg°C
Answer:

Explanation:
The answer would be Newton’s Second Law
Answer:


Explanation:

For transitions:


Thus solving it, we get:




Also, 
Where,
h is Plank's constant having value 
c is the speed of light having value 
So,


So,

Also, 
So,



It’s states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
