In a certain city, electricity costs .10 per k. w.h. what is the annual cost dor electricity to power a lamppost for 5 hours/day with a 100 watt incandescent light bulb

The annual cost is $18.25.

Step 1. years → days

1 yr × (365 days/1 yr) = 365 days

Step 2. days → hours.

365 days × (5 h/1 day) = 1825 h

Step 3. hours → watt-hours

1825 h × 100 W = 182 500 W·h

Step 4. watt-hours → kilowatt-hours

182 500 W·h × (1kW·h/1000 W·h) = 182.5 kW·h

Step 5. kilowatt-hours → dollars

182.5 kW·h × ($0.10/1 kW·h) = $18.25

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

it's all four options.
