Answer:

Large volumes of A'A' lava causes the steep slopes of stratovolcanoes (composite cones).

Explanation:

The A'A' lava has a rapid flow rate and bears a very high viscosity. This viscosity which is already low enhances as the lava flows rapidly and loses heat at a high pace. This combined action of A'A' lava ceases it from spreading on large areas and results in the formation of steep slopes. The Pahoehoe lava can also act like A'A' lava if the slopes are already steep.

Answer:

The ratio of asteroid-A’s acceleration to asteroid-B’s acceleration is 37:7800.

Explanation:

Mass of asteroid-A = m = $7.80\times 10^{20} kg$

Mass of asteroid-B = m' = $3.70\times 10^{18} kg$

As we know , Force = mass × Acceleration

1) Force on an asteroid-A

$F = m\times a$

where , a is the acceleration due to force applied on asteroid-A

2) Force on an asteroid-B

$F' = m'\times a'$

where , a' is the acceleration due to the force applied on asteroid-B

Same force is exerted on the both the asteroids say F.

F = F'

$m\times a=m'\times a'$

$\frac{a}{a'}=\frac{3.70\times 10^{18} kg}{7.80\times 10^{20} kg}=\frac{37}{7800}$

The ratio of asteroid-A’s acceleration to asteroid-B’s acceleration is 37:7800.

Answer: syncretism

Explanation: natural mixture of different traditions (in terms of language, religion, cuisine etc.), we could use also words as "hybridity" or "hybridization". In the case of Brazil we can speak about mixture of African religious/animistic cults with Catholic religions and indigenous beliefs. Carribean cultures suffered the same degree of syncretism.
