Answer:
magnitude: 100 N direction: east
Explanation:
The electrostatic force between two charges is given by
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the charges
In this problem, we have
Substituting into the equation, we find the magnitude of the force
Concerning the direction, let's notice that:
- Both charges are positive, so the force between them is repulsive
- The charge q1 is west of the charge q2
- So, the force applied by q1 on q2 must be to the east (away from charge q1)
C)
Plasma is the most abundant state of matter in the universe and has the most kinetic energy. It can be found in all the planets of our solar system, the sun, and other stars
Answer:
need Read this excerpt from "Not a Dove, But No Longer a Hawk."
Despite these misgivings, I do not see how we can do anything but continue to prosecute the war. We can and should limit the violence and the suffering being inflicted on the civilians as much as possible, but for whatever reasons, successive Administrations in Washington have carried the commitment in Vietnam to the point where it would be very difficult to prevent any precipitate retreat from degenerating into a rout. If the United States were to disengage from Vietnam under adverse conditions, I believe that the resulting political and psychological shockwaves might undermine our entire position in Southeast Asia.
Which statement best describes the paradox in this excerpt?
The author acknowledges that civilians should not suffer, but states that the civilians must retreat.
The author suggests that the administrators in Washington are busy making policies while overlooking the need to end the war.
The author acknowledges that the violence should stop, but admits that a retreat might have dire consequences.
The author suggests that the Vietnamese people are counting on US support, though their political ideals are not democratic.
Explanation:
Answer:
Here we have some of the requirement of practical fuel are
1. It must contain large amount of stored energy. So that more amount of power output available to run the engines, motors etc.
2. It must occur in abundance in nature or be easy to produce.
3. The fuel must be made up of elements that combine easily with oxygen. Foe example if hydrogen molecules reacts with oxygen. Then the products are at the reaction of lower energy than the reactants, the result is the explosive release of energy and the product of water.
Medium stars become dwarf stars, large stars become either neutron (pulsar) stars or black holes
