Antara berikut yang manakah tidak sama dengan 1 kwh ;? a) 3.6 * 10 ^ 4 watt kedua b) 6 * 10 ^ 6 c) 1.34 jam kuda jam d) 80.43 kuasa kuda kedua

Jawapan:

# "(a) dan (d)" #

Penjelasan:

a)

# => 3.6 × 10 ^ 4 "W s" #

# => 36 × 10 ^ 3 "W s" #

# => 36 "kW s" #

# => 36 "kW" × membatalkan "s" × "3600 jam" / (membatalkan "s") warna (putih) (…) 1 = "3600 hr"

# => warna (merah) (129600 "kWh") #

#color (putih) (…) ---------- #

b)

#=> 6 × 10^6 ?#

Tiada unit. Tidak boleh katakan

#color (putih) (…) ---------- #

c)

# => 1.34 "Jam kuasa kuda" #

# => 1.34 membatalkan "Kuasa kuda" × "745.7 Watt" / (1 membatalkan "Kuda kuasa") "jam" #

# => 999.28 "Jam watt " #

# => color (blue) ("Kira-kira 1 kWh") #

#color (putih) (…) ---------- #

d)

# => 80.43 "Kuda kuasa kedua" #

# => 80.43 membatalkan "Kuasa kuda" × "745.7 Watt" / (1 membatalkan "Kuda kuda") × membatalkan "s" × "1 jam" / (3600 cancel "

# => 16.66 "jam watt " #

# => color (merah) ("0.0166 kWh") #
