Answer:
bulk density = 1400 kg/m³
bulk density after compaction = 1750 kg/m³
Explanation:
given data
volume = 0.5 m³
porosity = 40%
oven-dry weight = 700 kg
reduce the total porosity = 20%
to find out
bulk density and bulk density after compaction
solution
we know bulk density formula that is
bulk density =
...............................1
put here value we get
bulk density =
bulk density = 1400 kg/m³
and
if porosity decrease 20 % that mean volume change
so total volume = 0.5 
total volume = 0.4 m³
so bulk density after compaction is from equation 1
bulk density =
bulk density after compaction = 1750 kg/m³
The longest spit in the world is the Arabat Spit in the Sea of Azov. It is approximately 110 kilometres (68 mi) long. The longest spit in a freshwater body of water is Long Point, Ontario, which extends approximately 32 km (20 mi) into Lake Erie. Hope this helps!
Answer:
1) The Indo-Gangetic Plain is one of the most fertile farming regions in the world. The Indo-Gangetic Plain is also the most heavily populated part of South Asia. In fact, the area contains about three-fifths of India's population.
The Indo-Gangetic Plains of India consists largely of alluvial deposits which are brought down by the rivers originating from the Himalayas and the peninsular region. The alluvial soil is fertile in nature. The rich deposits of this soil make this area suitable for agriculture.
2) From the late 1960s the Green Revolution transformed agricultural production, food security and livelihoods in South and Southeast Asia. The outcomes of this transformation are still being felt throughout the region.
3) South Asia is the seat of many of the world's great religious traditions, most notably Buddhism, Hinduism, jainism and Islam. Buddhism was established in the fifth century B.C.E
Answer:
The closest group of asteroids to our Sun is called the Asteroid Belt. It is 329 million to 478.7 million km away from our Sun.
Explanation:
No other group of asteroids is closer than this one. You can find the Asteroid Belt between the orbits of Jupiter and Mars. Half of the mass of these asteroids is from asteroids Ceres, Vesta, Pallas, and Hygiea.
