Answer:

  • the side of the volcanoes and other pyroclastic ejecta become saturated with water

Explanation:

  • A pyroclastic flows can generate the lahar when they are extreme ty hot and flows with the rocks bedrock. This debris mixes up with the snow met and ice and gets rapidly traveled upwards.
  • It travels rapidly down steep slopes and a larger can also be formed when a high volume of long duration of rainfall occurs after the eruption. And the volcanic landslides are mixed with water.

2. One ancient tradition in Japan that remains part of daily life is respect for
bonufazy [111]

Answer:

B. elderly people

Explanation:

I don't know if this counts but personally growing up in an Asian community, I think it's safe to say we pretty much worship our elders and if we didn't we'd be in big trouble.

So why is it B.?

Respecting the elderly is an ancient Asian tradition, and is also a part of daily life in terms of respect. B. falls into both categories.

Why is it not the others?

Japanese have just incorporated urban life and trendy fashion into their life and not any sooner than this generation so not A.

Outsiders is not very relevant to the answer because if you're an outsider, so be it so I wouldn't say C.

Asians think more for family than theirselves which is why it wouldn't be D.

3. A space vehicle is traveling at 4300 km/h relative to Earth when the exhausted rocket motor (mass 4m) is disengaged and sent
kvv77 [185]

Answer: Vce= 4234.4km/hr or 1180m/s

Explanation:

Mass of rocket motor Mr= 4m

Mass of control module Mc= m

Initial velocity of spaceship relative to earth Vs= 4300km/hr

Final velocity of command module relative to the rocket motor Vrc = 82km/hr

Total mass of spaceship M= 4m+m= 5m

Using law of conservation of momentum;

MVs= MrVre + McVce eqn1

Vre = Vrc+Vce eqn2

Where Vce is velocity of control room relative to the earth and Vre is velocity of rocket motor relative to the earth

Substituting eqn2 to eqn1, we have.

MVs= Mr(Vrc+Vce) +McVce

MVs= MrVrc+MrVce+McVce

Making Vce the subject of formula.

Vce = (MVs-MrVrc)/(Mc+Mr)

Substituting the values we have,

Vce = (5m×4300km/hr - 4m×82km/hr)/ (m+4m)

Vce = 21172m/5m

Vce= 4234.4km/hr or 1180m/s
