Answer:
a)3312 x 10⁴ J
b)I = 57.5 A
c)9200 W
Explanation:
Given that
P =4600 W
Time t= 2 h = 2 x 3600 s= 7200 s
We know that
1 W = 1 J/s 
a)
Energy stored in the battery = P .t
                                               =4600 x 7200 J 
                                              =3312 x 10⁴ J
b)
We know that power P given as
P = V .I
V=Voltage  ,I =Current
4600 = 80 x I
I = 57.5 A
c)
The energy supplied = 4600 x 2 = 9200 W
 
        
             
        
        
        
Answer:
(a) ΔP=0.0245 kPa
(b) P=9.14 kPa
(c)ΔP=0.0245 kPa
Explanation:
(a) As it is perfect gas we can use
(P₁V₁)/T₁=(P₂V₂)/T₂
Since this constant volume so
P₁/T₁=P₂/T₂
T₂ is change in temperature
T₂=1.00+273.16
T₂=274.16 K

ΔP=6.71449-6.69
ΔP=0.0245 kPa
(b) As 

(c) Same steps as in part (a)

ΔP=9.164-9.14
ΔP=0.0245kPa
 
        
             
        
        
        
Its (a) and(a)for the other ? and the last one is (d)
