Answer: Some conversions from one system of units to another need to be exact, without increasing or decreasing the precision of the first measurement. This is sometimes called soft conversion. It does not involve changing the physical configuration of the item being measured.
Explanation:
Power = 
Delilah: 170J/30s = 5.66 W
Adam: 260J/20s = 13 W
Answer:
why did the parents let go of their child-
Explanation:
A 5 kg, because 90 / 18 is 5
the resistance is 80.8Ω and average power 178.2 W
a) the value of resistance is given as,
R=rms voltage / rms current
and rms current = 2.1/√2
= I°/√2
rms current = 2.1/√2
rms current = 1.48
therefore R = 120/1.48
=80.4Ω
b) average power is product of rms current and rms voltage
P=120× 1.48
=178.2 W
