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>
Answer:
122.5 N
Explanation:
The free body diagram in the bucket at the top of the circle is shown in the attached image.
The force balance hence, is
T + mg = mv²/r
where T = tension in the rope = ?
mg = weight of the bucket system
mv²/r = force keeping the bucket in circular motion.
v = velocity of the bucket = 7.8 m/s
r = radius of the circular path = 1.0 m
T + mg = mv²/r
T + (2.4×9.8) = (2.4×7.8²)/1
T = 146.016 - 23.52 = 122.496 N
