Answer:
Explained below
Explanation:
When we eat food, our body gets chemical energy from it. Now, this chemical energy from the food is changed into some different energy forms that is useful to it. They include:
-Chemical to mechanical energy to aid in movement of muscles
- chemical to thermal energy to aid in regulating the body temperature.
- chemical to electrical energy to aid the brain in thinking.
Thus is similar to how a machine converts energy because machines also generate energy after being powered and convert to other forms of energy. For example, an alarm clock converts electrical energy to sound energy, hair dryer converts electrical energy to thermal/heat energy.
W= FxD. Since the weight is not put into force you’re going to convert it by multiplying it by 9.8 (gravity). 76kg x 9.8 = 7448. Then multiply that by the distance (2.5). Your answer is 1862.
The electric flux is changed only if we change the charge.
<h3>What is the expression of electric flux?</h3>
- As per gauss law, total electric flux link through a surface is equal to (1/ε0) × charge.
- Mathematically, electric flux = q/ε0
- q = total charge enclosed by the gaussian surface
- Here the electric flux is directly proportional to the charge, so on changing charge, the electric flux changes.
Thus, we can conclude that the electric flux is changed only if we change the charge.

Answer:
Human activity such as soil stripping, mining dangerous agricultural practice causes and affects erosion and sedimentation.
The earth operates a balanced process such that the earth produce it self at about the same rate as it erodes. So if humans are stripping the soil at a rate greater than the rate at which the soil is forming itself, the soil wont be able to keep up, thus leading to erosion.
Sedimentation on the other hand is the process whereby by particle settle at the base of the carrying body due to the force of gravity.
As humans, mining activity most importantly at times dissolves particles which travels down to the core and are then moved to another location by erosion. this implies that the strength of the soil of that location becomes weak.
