Answer:

3.67 A

Explanation:

The power rating is related to the voltage and the current by the following equation:

P=VI

where

P is the power rating

V is the voltage

I is the current

In this situation, we have:

P = 11 W

V = 3 V

I = ?

So, we can re-arrange the equation to calculate the current used:

I=\frac{P}{V}=\frac{11 W}{3 V}=3.67 A

Earth's original atmosphere was probably just hydrogen and helium, because these were the main gases in the dusty, gassy disk around the Sun from which the planets formed. The Earth and its atmosphere were very hot.

2 76 Consider a household that uses 14,000 kWh of elec- (tricity per year and 3400 L of fuel oil during a heating sea- son. The
NNADVOKAT [17]

Answer:

The total amount of CO₂ produced will be  = 20680 kg/year

The reduction in the amount of CO₂ emissions by that household per year = 3102 kg/year

Explanation:

Given:

Power used by household = 14000 kWh

Fuel oil used = 3400 L

CO₂ produced of fuel oil = 3.2 kg/L

CO₂ produced of electricity = 0.70 kg/kWh

Now, the total amount of CO₂ produced will be = (14000 kWh × 0.70 kg/kWh) + (3400 L × 3.2 kg/L)

⇒ The total amount of CO₂ produced will be = 9800 + 10880 = 20680 kg/year

Now,

if the usage of electricity and fuel oil is reduced by 15%, the reduction in the amount of the CO₂ emission will be = 0.15 × 20680 kg/year = 3102 kg/year
