Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.
D. high and low levels of silica in the different type of lava.
Explanation:
The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.
Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.
4 men x 8 days = 32 days work content & 6 women x 8 days = 48 work content
6 women at 1/400 per day x 8 days is 48/400. 352+ so 1 mans daily output is 11 work units per day x 4 men = 44 work output per day x 8 days = 352 total work output
3 men x 10 days = 30 days work content & 7 women x 10 days = 70 work content
1 man work output is 11 x 3 men x 10 days = 333 work units
one woman’s work output is 1/400 per day x 7 women = 7/400 per day x 10 days = Total of 70 work output plus men’s output of 330 = 400 work units.
10 women x 40 days = 400 work content
so if 10 men carried out the work its 11 x 10 men = 110 work units per day
400 work units + 110 work units per day = 3.6363 days work for 10 men.
1 women daily work output = 1/400 unit per person x 10 women or 10/400 work units per day so 10 x 40 days
4 Men & 6 Women = 8 days (men = 4 x 8 x 11 = 352)( 6 x 8 x 1/40 = 48/40
3 Men & 7 Women=10 days (men = 3 x 10 x 11 = 330)(7 x 10 x 1/40 =70/40)
10 women at 1/400 each per day x 40 days is 400 work units
while 10 men x 11 units is 110 units per day so for 400 units it’s 3.6363 days
1 man is equal approximately to 11 Women
10 men can do job in 3.6363 days x ratio of 11 =
Answer: It will taken 10 women x 40 days to complete the same job.
