If an electric iron of 1200W is used for 30minutes every day, find electric energy consumed in the month of November. Also calculate bill amount if the rate of 1 unit = Rs 2

Electric energy produced in the month of April is 18 kWh

Explanation:

Given

P = 1200 W = 1.2 kW      

Use time per day = 30 minutes = 1 / 2 hrs

We know,

No. of days in April = 30 days

Total time iron being used

T = 1 / 2 * 30 = 15 hrs

We know,

Energy consumed = Pt

Substituting the value of P and T

= 1.2 kW * 15 hr

= 18 kWh    

Hence,

Electric energy produced in the month of April is 18 kWh

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
