Answer:
all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics
Explanation:
Electrostatic interactions, have many rare manifestations in nature, which causes many reasons to study them.
- Lightning is a very striking form of electricity
- The biological processes are governed by currents of inanes and potential differences
- The transfer of nutrients and fertilizers to plants is with ion exchange, electrostatic forces
- all modern electronics is based on electricity
- the electric charge in very dry places, creates high currents that can create fires or kill people
In summary all areas of knowledge that wish to understand the physical, chemical and biological process must know electrostatics

Answer:
0m/s²
Explanation:
The acceleration of the given body whose motion has been described will be zero.
This is because the body moves with a constant velocity.
Acceleration is defined as the rate of change of velocity with time.
Since in this problem, the velocity is not changing per time, then the acceleration would be zero.
A body moving steadily implies that such body is not changing its motion by the virtue of its velocity and even direction.
Answer:
The magnitude is 63 kg m²/s, and the direction is -k.
Explanation:
Plug the values into the equation:
L = m v×r
L = (3.0 kg) (<5 i + 3j> m/s × <2i − 3j> m)
Take the cross product. The cross product of two dimensional vectors is:
<v₁ i + v₂ j> × <r₁ i + r₂ j> = <(v₁ r₂ − v₂ r₁) k>
Therefore:
L = (3.0 kg) <((5)(-3) − (3)(2)) k m²/s>
L = (3.0 kg) <-21 k m²/s>
Multiply:
L = <-63 k kg m²/s>
The magnitude is 63 kg m²/s, and the direction is -k.
