I believe the correct answer is true.
Hope this helps! ;)
Answer:
27.32 J/k Mole.
Explanation:
The constant pressure heat capacity of hydrogen is given by Shomate equation
C_p= a + b×t + c×t^2
C_p = heat capacity (J/mol*K)
t = temperature (K) / 1000.
Temperature =25°C=298 K
t= 298/1000 =0.298
putting values we get
C_p = 27.28+3.26x10^-3 ×0.298+0.50×(0.298)^2
C_p=27.32 J / K mole
the value of the constant pressure heat capacity of hydrogen at 25 °C=
C_p=27.32 J / K mole
Answer:
c = λf
E = h f
the characterization of electromagnetism is given as a function of energy or frequency.
Explanation:
In waves the frequency and donut length are related by the speed of the wave
c = λf
therefore the two quantities are not independent.
The energy of an electromagnetic wave is given by
E = h f
where h is the planck constant and f the frequency of the wave
This energy determines how the wave interacts with the surrounding medium. Low energy waves only create movement of the atomic nuclei and as the energy increases, the electrons are excited.
As a result of the above, the characterization of electromagnetism is given as a function of energy or frequency.
Answer:
GPE=98J if the given gravity is 9.8 but the gravity is 10 it will be 100J
Explanation:
GPE=mgh so m=8kg g=9.8m/s^2 or 10J h=1.25m
so GPE=8kg×9.8 or 10 m/s^2×1.25m
GPE=98J if the given gravity is 9.8 and GPE=100 if the given gravity is 10.but ask your teacher (asker) and don't forget those formula
Answer :
1.33m/s²
Explanation :
a =vf - vi/t
a =28m/s/2.1s
a = 1.33m/s/s =1.33m/s²
