Answer:
<h2> $1.50</h2>
Explanation:
Given data
power P= 2 kW
time t= 15 min to hours = 15/60= 1/4 h
cost of power consumption per kWh= 10 cent = $0.1
We are expected to compute the cost of operating the heater for 30 days
but let us computer the energy consumption for one day
Energy of heater for one day= 2* 1/4 = 0.5 kWh
the cost of operating the heater for 30 days= 0.5*0.1*30= $1.50
<u><em>Hence it will cost $1.50 for 30 days operation</em></u>
its 13.98. it's simple multiplication 3* 4.66= 13.98
Melting ice would damage this polar bears habitat meaning the polar bear may decrease
That's silly. The volume of a gas is very intimately related
to the volume of its enclosure. In fact, they're identical,
because a gas always expands to fill whatever you put it in.
