Oliga [24]3 years ago
5 0

Answer:

Solar flares are massive explosions of energy in the Sun's atmosphere.

The new technique allows changes in the Sun's magnetic fields, which drive the initiation of solar flares, to be monitored up to ten times faster than previous methods.

In general, the highest relative humidity is observed ___________ and the lowest relative humidity is observed _____________
nikdorinn [45]

In general, the highest relative humidity is observed NEAR SUNRISE and the lowest relative humidity is observed during MID-AFTERNOON.

Relative humidity is inversely proportional to temperature. The colder the climate, the higher the relative humidity. The hotter the temperatures outside, the lower the relative humidity.

Relative humidity increases as the air temperature falls at night and peaks at dawn.  

Temperature peaks during mid-afternoon, thus relative humidity is at its lowest.

A rock is going to be analyzed for its radioactive isotope contents, X and Y. X is the parent and Y is the daughter isotope. Ass
aev [14]

Answer:

C) X=100%; Y=0%

B) X=50%; Y=50%

Explanation:

The oldest rocks on Earth are about four billion years old. When a rock forms, it contains unstable isotope and no daughter isotopes, so every rock will contain 100% parent isotope and 0% daughter isotope.

The half-life of the radioactive isotope Of this particular rock is 5730 years. The half-life is an amount of time needed for half of the parent isotope (50%) to become a daughter isotope. In this case, after 5730 years, half of the initial parent isotope will transform to daughter isotope, which means that after 5730 years, there will be 50-50 of the parent and daughter istotopes presented in the rock. After two half-lives, there will be only 25% of the parent isotope remaining (that’s half of the previous 50% which remained after first half-life), and after three half-lives, there will be only 12,5% of the parent isotope remaining and so on.
