The Earth's core is very hot and does have some effect on the temperature above ground. But the major cause of global warming is the trapping of infrared radiation from the Sun.

Health - X-ray Risks

Are x-ray hazards based on age?

May 7, 2008

Question

Are X-Ray hazards are also based upon Age, OR

What If a 6 month old & 5 1/2 yrs old Child AND 86 yrs old person exposed to Medical & dental X-Ray?

What Is Panaromic X-RAy?

ashwini - India (15900)

Answer

It is always good to make sure an x-ray is necessary, especially with a young child. Since young children are growing so fast, the risk from an x-ray is greater than for an older person.

Dental x-rays with modern equipment are very safe, since the amount of radiation is low. A panoramic x-ray is a series of x-rays, usually of the teeth in the whole mouth.

Medical x-rays have more energy, but they are still quite safe with modern equipment. An adult could have 100 dental or medical x-rays in a year and have little risk of getting cancer. A young child could probably have 10 x-rays and still be safe. But it is always good to let your concerns be known to the doctor.

Science Experiment - Fluids

Can a peanut or walnut explode in lemonade?

May 7, 2008

Question

Can a peanut or walnut explode in a glass of lemonade? Is it possible?

Diana - USA (15905)

Answer

The peanut or walnut must be airtight for it to possibly burst or explode. Usually they have cracks that allow air pressure to escape. I have heard that walnuts will fizz in lemonade.

It would be easy to try, but I feel the idea is an urban myth that has been going around the Internet.

May 9, 2008

Question

why we use pressure cooker on hilly areas.atmospheric pressrue increas or decreas on hieght.

bushra - Pakistan (15912)

Answer

As you go to higher elevations, the air pressure or atmospheric pressure decreases. That means that the relative pressure inside a pressure cooker would be greater than it would be at lower elevations. Thus, the pressure cooker should work better at higher elevations.
