The light bulb produces 1.15 J  energy in 1 second.

<u>Explanation:</u>

Efficiency of an electric appliance is defined as the ratio of output power to the input power. In a 100% efficient appliance all of the input power will be converted to output power. In the given question  it is given that

input power= 10W  

efficiency= 11.5%

(output power)/(input power)=efficiency  

output power = input power * efficiency

=10 \times (11.5/100)=1.15W

Now we have to calculate the energy produced by the light bulb in 1 second

energy=power \times time

=1.15 \times 1

=1.15J

Answer: In the restaurant business, the use of plastic can sometimes be unpreventable, as it serves many purposes and plays a vital role in our consumption of food. One of the great advantages of plastic is that it’s designed to last for a very long time: nearly all of the plastic ever created still exists in some form today. It is in use all around us — from protecting products, to the interior of our cars, to preserving food, to the medical devices used in hospitals every day. While there are numerous positive characteristics of plastic, there are also some considerable negatives. Every day, many plastic items are only used once and then are thrown away, generating one of the fastest growing problems for the environment. We call this “single-use plastic.”

There are countless amounts of plastic items in our landfills and additionally, in our lakes, rivers and oceans. Since it takes years and years for plastic to decompose, it can release toxic chemicals into our soil and water, which can affect human health and wildlife.

With this in mind, it is important not only for individuals to reduce their plastic use, but for restaurants to lead in example by reducing the amount of plastic generated in the workplace. Many large companies like Starbucks, IKEA, and Disney have already committed to eliminating single-use plastic waste in the near future, and we expect many others will follow suit. Here are five tips to help contribute to reducing plastic waste:
