1 answer:

8 0

Answer: Map scale can be defined as the relationship that can be drawn in between the length of the map and the length of the ground.

Explanation:

The unit of the length on the map and the corresponding length of the ground is the map scale. The type of map scales:

Large Scale 1:25,000 or more

Medium Scale 1:1,000,000 to 1:25,000

Small Scale 1:1,000,000 or less

Small scale and medium scale can demonstrate large area for example a country or state whereas the large scale can demonstrate a small area like a city or region of city.

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

Vladimir79 [104]

Answer:

Evaporite minerals formed from restricted open ocean circulation with high evaporation rates

Explanation:

Salts like halite and gypsum are called evaporites.

Evaporites are chemical sedimentary rocks that forms when water in a basin(oceans, lakes) are restricted to flow and evaporation causes precipitation of the minerals dissolved in the water.

Halite and gypsum form insolube precipipate that accumulates over a long period of time in such an environment. The formation of evaporite largely depends on the dissolved load of a sediment and the environment of depositon of the load.

What types of issues do government officials face when recovering after such a major disaster like the tsunami in japan? How can

dexar [7]

Answer:

In the aftermath of the nuclear crisis in Japan, the country engaged in a massive cleanup. It cleared tons of debris, rebuilt roadways and bridges, and demolished and cleared out damaged buildings. In the future, plans should be in place for organizing citizens in cleanup efforts, making the streets safe during cleanup, and safely disposing of debris.

In addition, public transportation and airports need to function as soon as possible after such an event. Therefore, government staff should develop disaster-recovery plans for the most vital transportation systems. Local governments also need to provide short-term and longer-term housing for those who lose their homes. Designated shelters, such as schools or other community buildings, should be made ready for this purpose. Governments also need to help people get insurance payments, loans for rebuilding, and sound advice for where to locate new homes and how to strengthen them.

Explanation:

Exact answer, so you should paraphrase.
