An electrical company charges 15 p per unit of energy (kWh). Calculate the cost of running a 500 W freezer for a day. Show your working.

180 p

Explanation:

Energy refers to the capacity of doing work.

Amount charged by an electrical company = 15 p per unit of energy (kWh)

As 1 W = 1000 kW,

Also, 1 day = 24 hours.

Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour =

Therefore,

cost of running a 0.5 kW freezer for a day ( 24 hours ) =

Amount charged by an electrical company = 15 p per unit of energy (kWh)

As 1 W = 1000 kW,

Also, 1 day = 24 hours.

Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour =

Therefore,

cost of running a 0.5 kW freezer for a day ( 24 hours ) =

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
