Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
Japan because the names are Japanese and there is a lot of small islands around japan
Answer:
SW
Explanation:
When a hurricane intensifies and the wind speed increases, an eye begins to form in the center of the storm. This normally occurs once the winds reach about 80 mph. Almost always the eye is circular when viewed from above, and measures about 20 to 40 miles in diameter. It looks cylindrical in a cross section of the storm, and extends through the center of the storm like a chimney. The air over the storm sinks through the center of the eye.
Hurricanes are formed from centers of low atmospheric pressures in warm waters around which strong air currents begin to circulate.
When ocean water heats up, the air rises and swirls to fill the low pressure that this creates.
This causes the air to be sucked in and up, which reinforces the low pressure in the center.
Thus, when the wind speed increases to 128 km / h, a kind of "vacuum" is created that meteorologists call "eye", since it has an almost circular shape.
