Answer: you cant possibly have a wave going 200 meters per second or miles per second so then it would be 10
Explanation: test i did
Ya know what you’re saying about the kids who don’t like men like me but they always seem
It would be the first one and the third one
1) 29.8 C
At the beginning, the metal is at higher temperature (70.4 C) while the water is at lower temperature (23.6 C). When they are put in contact, the metal transfers heat to the water, until they reach thermal equilibrium: at thermal equilibrium the two objects (the metal and the water have same temperature). Therefore, since the temperature of the water at thermal equilibrium is 29.8 C, the final temperature of the metal must be the same (29.8 C).
2) 6.2 C
The temperature change of the water is given by the difference between its final temperature and its initial temperature:
where
Substituting into the formula,
And the positive sign means that the temperature of the water has increased.
3) -40.6 C
The temperature change of the metal is given by the difference between its final temperature and its initial temperature:
where
Substituting into the formula,
And the negative sign means the temperature of the metal has decreased.
Answer:
Due to the Electric Charge Conservation Law, the statement is <u><em>true.</em></u>
Explanation:
Conservation laws state that the physical properties or magnitudes of a given system have a constant value, that is, they cannot change.
Electric charge is a property that exists in some subatomic particles, manifested by attractions and repulsions that give rise to electromagnetic interactions.
The electric charge is governed by the principle of conservation of the charge. This law establishes that the total load in an isolated system is constant, that is, it is not possible to create or destroy isolated loads. That is, they can only be moved from one body to another or from one place to another inside the given body.
As mentioned, this law is only valid for closed systems in which no charged particles enter or leave outside. Then it is concluded that the algebraic sum of the charges of all particles remains constant.
Finally, <u><em>due to the Electric Charge Conservation Law, the statement is true.</em></u>
