Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering- resistant rocks, such as quartzite, given the right conditions.

Answer and Explanation:

The answer is <u>D) Alpha and Gamma</u>

Gamma radiation does not cause transmutations.

A <u>transmutation</u> is the <u>conversion of an atom of one element to an atom of another. This generally occurs through nuclear reacting.</u>

There are three main types of radiation: alpha, beta, and gamma. Both beta and alpha decay cause changes to the mass and atomic numbers. This results in a transmutation. Gamma radiation, however, does not.

Gamma radiation is the result of a gamma ray. In essence, the nucleus emits a high-energy proton. This is very penetrating and can only be stopped by aluminum, lead, soil, water, and concrete. This type of radiation does not change the element and, therefore, does not cause a transmutation.

How many kj of heat are needed to completely melt 144 g of titanium metal, given that the metal is at its melting point? the hea
Elina [12.6K]

Given, mass of titanium metal = 144 g

Heat of fusion of titanium metal= 18.7 J/g

Heat of fusion is the amount of heat energy needed to change the state of one gram of a substance from solid to liquid or vice-versa.

Thus, 18.7 J of heat is needed to melt one gram of titanium metal.

Therefore, heat needed to melt 144 g of titanium metal = 18.7×144

= 2692.8 J

A wheel rotates clockwise 10 times per second. what is its angular speed answer
bogdanovich [222]
The frequency of the wheel is the number of revolutions per second:
f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz
And now we can calculate the angular speed, which is given by:
\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s in the clockwise direction.
