Answer: B. Proximity to water sources needed for subsistence farming

Basically, Sub-Saharan Africa is a continent of small landowners and its environments are very sensitive. Even with low population densities the soil starts to degrade and future production is threatened by the use of traditional methods.

With the exception of humid zones, climatic realities result in constant crop failures because of drought or dry spells in the growing season. The composition of most African soils consists of highly weathered granite and gneiss parent material, and since the capacity of African soils to hold water is poor, rainfall infiltrates soluble nutrients.

Finally, once vegetation is removed, the erosive action of water and wind eliminates the top soil and crusts appear in the surface making it sealed against infiltration.

if a woman in a plane waiting to parachute is 3,940m high and has a mass of 70kg,what is her gravitational potential energy (gpa

LiRa [457]

Answer:

$\boxed {\boxed {\sf 2,702,840 \ Joules }}$

Explanation:

The gravitational potential energy can be found using the following formula

$E_p=m*g*h$

Where m= mass, g= gravitational acceleration, and h = height.

We know the the mass of the woman is 70 kilograms and the height is 3,940 meters

If we assume this parachute is on Earth, then the gravitational acceleration is 9.8 m/s²

$m= 70 \ kg \\h= 3,940 \ m \\g= 9.8 \ m/s^2$

Substitute the values into the formula.

$E_p= (70 \ kg) (9.8 \ m/s^2)(3,940 \ m)$

Multiply the first two numbers first.

$E_p=686 \ kg*m/s^2 (3,940 \ m )$

1 kg*m/s² is equal to 1 Newton. Therefore, the first number (686 kg*m/s²) is also equal to 686 Newtons

$E_p=686 \ N (3,940 \ m)$

Multiply again.

$E_p= 2702840 \ N*m$

1 Newton meter is equal to 1 Joule. So, our answer of 2702840 N*m is equal to 2702840 J

$E_p=2702840 \ J$

The potential energy of the women is 2,702,840 Joules

Mariulka [41]

Answer:

Servant leadership theory.

Explanation:

A servant leader is that which serves first, leading from a place that helps those who she-he leads and not trying to abuse of that power or try to search for more. As the exercise exemplifies, Amara makes an effort to lead her employees by fostering teamwork, listening to her employees' concerns and helping them to grow.

Sociologists found that the effects of institutionalization on infants, i.e. lack of a caring environment, will result in slower

GuDViN [60]

Answer: True

Explanation: The lack of a caring environment can affect the mental development of children because studies have shown that children depend on their parents as a condition for a caring environment. Parental care of children is important in terms of regulating their physiological needs and behaviour, that is, in learning certain patterns that are important for mental development. With careful care, children are relieved of stress, which, if not eliminated, can later cause problems. Such children exhibit the developed skills needed for school, i.e learning, writing, reading, socialising, while neglecting can produce various mental, health, developmental problems.
