In which scenario is work being done according to the physical definition?

• A person holding a heavy box while standing still

• A tugboat pulling a barge

• A satellite orbiting the Earth

• A painting hanging on a wall

As the height of an object increases its gravitational potential energy __________________.

• DECREASES

• STAYS THE SAME

• KEEPS ON CHANGING

• ALSO INCREASES

Which type of circuit allows the remaining bulbs to continue working even if one bulb is busted?

• Parallel Circuit

• Series Circuit

• Both circuits

• Neither of the circuits

Which type of circuit is shown in the diagram?

• Simple Circuit

• Open Circuit

• Series Circuit

• Parallel Circuit

What type of circuit does the picture represents?

• Series Circuit

• Open Circuit

• Simple Circuit

• Parallel Circuit

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current flows in different path
