Question

Nomor 2 pilihan ganda ada yang tahu? Makasih sebelumnya

Answer 1

A-B = m.c.t
= 1x2100x10
= 21000 joule
B-C = m.l
= 1x336000
= 336000 joule
C-D = m.c.t
= 1.4200.10
= 42000 joule
A-B-C-D = 21000+336000+42000
= 399000 joule


jawabannya (C) 399.000 joule

Answer 2

A-B
Q=mc∆t =1 x 2100 x 10 = 21.000
B-C
Q=ml = 1 x 336.000 =336.000
C-D
Q=mc∆t = 1 x 4200 x 10= 42.000
jumlah seluruh = A+B+C= 21.000+336.000+42.000= 399.000 Joule (C)

Answer 3

A-B
Q=mc∆t =1 x 2100 x 10 = 21.000
B-C
Q=ml = 1 x 336.000 =336.000
C-D
Q=mc∆t = 1 x 4200 x 10= 42.000
jumlah seluruh = A+B+C= 21.000+336.000+42.000= 399.000 Joule (C)
