Answer:
D) 13.62 kg/L
Explanation:
This problem can be solved by a simple rule of three.
The problem states that Mercury has a dansy of 30 lbs/L, and asks what is the density in kg/L. We have to convert from lbs to kg.
Each lb has 0.454 kg? How many kg are there in 30 lbs?
So:
1 lb - 0.454kg
30 lb - x kg
This means that mercury's density in kg/L is 13.62, letter D. Letter A is also 13.62, however it is not in the unit asked.

Answer:
<u>Life expectancy index, Education index, Literacy index, Income index all the countries are ranked based on these parameters</u>.
Explanation:
- As HDI is a statistical composite index and the formula for calculating the Human Development Index is (life expectancy x education index x income index).
- The higher the score the higher is the value of the development of the country. Developed by Dr. Mahbub Al Haq and Amartya sen.
- The HDI shows low human development scores from 0.0 to 0.5. The medium human development scores between 0.5 and 0.8. High human development for HDI scores ranges from 0.8 and 1.0.
- Though there are limiting factors of HDI as it does not take into account the qualitative factors and cultural identity into considerations, As others have suggested the HDI should be more human-centered ranging from gender to environmental biodiversity.
Answer:
Metamorphic rocks (from the Greek meta, change, and morphe, form, "change of shape") result from the transformation of pre-existing rocks that have undergone structural and mineralogical adjustments under certain physical or chemical conditions, or a combination of both, such as the temperature, pressure and / or chemical activity of the fluids agents of metamorphism These adjustments, imposed exclusively under the surface, transform the original rock without losing its solid state, generating a metamorphic rock. The rock generated depends on the composition and texture of the original rock, the agents of metamorphism, as well as the time in which the original rock was subjected to the effects of the so-called metamorphic process. Due to the nature of their origin, there may be a complete gradation between metamorphic rocks and the igneous or sedimentary rocks from which they were formed. The study of these rocks provides very valuable information about the geological events that occurred within the Earth and about their variation through time.
Explanation:
To classify a metamorphic rock, the type of metamorphism involved must be known, which can be variable since it depends on the criteria that are taken as a basis to differentiate it: it can be classified from the point of view of extension, fit and cause , geological value, increase or decrease in temperature, etc., but it is very common to define three main types of metamorphism according to the predominant metamorphic agent: Regional, Contact and Dynamic.

Answer:
W°= 136
Explanation:
Here,
we get:
The base angles equal since it is isosceles triangle.
W°=68+68 (the exterior angle is equal to the sum of its two opposite interior angles.)
=136
