A machine does 1000 J of work in 3.5 minutes (210 seconds). What is

Physics
1 answer:
irina [24]3 years ago
4 0

Answer: 4.76 watts

Explanation:

Work = 1000 J

Time = 3.5 minutes (210 seconds)

Since the SI unit of time is seconds, 210 seconds will be used in calculation.

Power output of the machine = ?

Recall that power is the rate of doing work. Thus, power is Workdone divided by time taken.

i.e Power = (work/time)

Power = 1000J/210seconds

Power = 4.76 watts

Thus, the power output of the machine is 4.76 watts

Convert the mass to kgs thanks
Natali [406]
Memorize this and you'll be able to do ALL of these:  <em>1  kg = 1,000 g</em>

So if you have some grams, divide the number by 1,000 to get kilograms.

1,000 g = 1.000 kg

500 g = 0.500 kg

100 g = 0.100 kg

50 g = 0.050 kg

20 g = 0.020 kg

10 g = 0.010 kg

Capacitors, C1 = 1.0 F and C2 = 1.0 F, are connected in parallel to a 6.0 volt battery (ΔV = 6.0V). If the battery is disconnect
Iteru [2.4K]

Answer:

66.2 sec

Explanation:

C₁ = 1.0 F

C₂ = 1.0 F

ΔV = Potential difference across the capacitor = 6.0 V

C = parallel combination of capacitors

Parallel combination of capacitors is given as

C = C₁ + C₂

C = 1.0 + 1.0

C = 2.0 F

R = resistance = 33 Ω

Time constant is given as

T = RC

T = 33 x 2

T = 66 sec

V₀ = initial potential difference across the combination = 6.0 Volts

V = final potential difference = 2.2 volts

Using the equation

V = V_{o} e^{\frac{-t}{T}}

2.2 = 6 e^{\frac{-t}{66}}

t = 66.2 sec
