Answer:
Explanation:
Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.
Force = mass x acceleration
Apply this equation on Rachel
T₁ = 23 x 2 = 46 N
Let T₂ be tension between Sarah and me and it is inclined at 60°
Force = mass x acceleration
Apply this equation on Sarah
T₂ cos 60 - T₁ = 23 X 2 = 46
T₂ cos 60 - 46 =46
T₂ cos 60 = 92
T₂ = 92 / .5
= 184 N
One kilowatt-hour = 1000 watts = 1000 joules/second
One hour = 60 × 60 = 3600 seconds
One kWh = 3600 × 1000 joules
One kWh = 36 × 100000 joules
One kWh = 3.6 × 10 × 100000 joules
One kWh = 3.6 × 10⁶ joules
