Answer:
+131Joules
Explanation:
Energy can be expressed using below expresion.
ΔE = (q + w).........eqn(1)
q will be + be if heat is gained hence, q= 240 J
work "w" will be - ve if work is done by the system, hence w= -109 J
Then substitute into eqn(1)
Change in Internal energy=
= (240 -109 )
= +131J
The earth
The earths mass is what generates the force to draw you in. The deeper you go, sorry the more above you the less the pull will be
E = hf
E : photon energy
h : Plank's constant 6.63×10^-34
f : frequency
Hope it helped!
I will go to school tomorrow .....is this present tense or past tense or future tense
