A person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mech anism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time: (a) How many people would it take to run a 4.00-kW electric clothes dryer?
1 answer:
Answer:
40 persons
Step-by-step explanation:
Data provided :
The power put out by a single person = 100 W
Power required by an electric clothes dryer = 4.00 kW = 4000 W
Thus,
The number of persons required to produce 4000 W of power
= ( Power required ) / ( power produced per person )
or
= (4000 W) / (100 W/ person)
or
= 40 persons
Hence, the number of persons required is 40

Hello!
1) -3x - 4 = 23
-3x = 23 + 4
-3x = 27
x = 27 : (-3)
x = - 9
2) x/2 - 12 = -4
x - 24 = -8
x = -8 + 24
x = 1 6
3) 6a + (-1) = 10
6a - 1 = 10
6a = 10 + 1
6a = 11
a = 11 : 6
a = 1 1 / 6
4) -(x + 2) = 12
x + 2 = -12
x = -12 - 2
x = - 1 4
5) 7a + 12 = 10
7a = 10 - 12
7a = -2
a = -2 : 7
a = - 2 / 7
6) -4(a + 2) = 12
a + 2 = -3
a = -3 - 2
a = - 5
Good luck! :)
