The comet has no net force acting on it, which results in constant velocity. Near our solar system, the influence of the gravitational forces due to the sun and the planets will increase as we know that gravitational force is:
F = GMm/r²
The net force will produce an acceleration on the comet, which will cause its velocity to change.
Answer:
The current through the circuit element will also be doubled.
Explanation:
The relationship between voltage and current of a circuit element is given by Ohm's Law. According to Ohm's Law:
Voltage = (Resistance)(Current)
If the resistance of the element is kept constant, the relation between Voltage and Current through that element becomes as follows:
Voltage = (Constant)(Current)
Voltage α Current
Thus, the voltage is directly proportional to the current for constant value of the resistance.
Therefore, when the voltage across a circuit element of constant resistance is doubled, <u>the current through the circuit element will also be doubled.</u>
