A cause and effect due to process of elimination and the text
Answer:
4. Solar energy makes food grow. By eating the food we can create a store of chemical energy inside us. We can use this stored energy to do work like wind an alarm clock. The clock now has potential energy.
5. You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic
6. As a pendulum swings, its potential energy converts to kinetic and back to potential. Recall the concept of conservation of energy—that energy may change its form, but have no net change to the amount of energy.
7. Renewable resources def: ways to generate energy from (theoretically) unlimited natural resources. These resources are either available with no time limit or replenish more quickly than the rate at which they are consumed
Examples of Renewable resources
• Solar energy.
• Wind energy.
• Geothermal energy.
• Hydropower.
• Bioenergy.
Nonrenewable resources def: A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. An example is carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas

The capital of Russia is Moscow. For centuries, the capital of Russia had been St. Petersburg, named after the Russian tsar Peter I. However, after its violent transition to communism in the early 20th century, Moscow was adopted as the new capital. It is also the largest city in Russia, with a population of close to 17 million people.
The capital of Ukraine is Kiev. Kiev is one of the oldest cities in eastern Europe and played an important economic role when it was encompassed by the Soviet Union. However, Ukraine regained its independence in 1991 and Kiev is still its capital.
The capital of Latvia is Riga, which has a tradition of an industrialized Baltic seaport. With close to 650,000 inhabitants, Riga also happens to be the largest city in the three Baltic states of Estonia, Latvia, and Lithuania.
