Answer:
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
Fats must be broken down into fatty acids before being converted into glucose. Lipids are known as the back up energy source. They are used to make enzymes, hormones, and antibodies.
You may not operate a vehicle unless all child passengers FOUR YEARS OF AGE AND UNDER are properly restrained with an appropriate safety device.
Traffic law requires that children four years and below must be properly restrained in the vehicle using appropriate devices such as car seats.
Children older than four years have to use the safety belt when they are inside the car.
Answer:
It will eventually become less bright and cooler.
Explanation:
Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.
