Answer:
Explanation:
Given
Distance between two electrons arranged in equilateral triangle geometry is
Potential Energy Between two system
where and are charges and r is the distance between them
For three Charges Potential Energy is given by
No, both the cars do not have the same velocity.
Velocity is a vector quantity and it is the rate of change of displacement with time or change in speed with direction.
Velocity has both magnitude and direction. So when you are in a car going 70 km/h and another car goes in the opposite direction at 70 km/h their velocities are different.
How?
Consider your car as moving in the positive direction, so its velocity will be 70 km/h and for the car moving in the opposite direction, since the direction is opposite, the velocity of that car will be -70 km/h. This is because, the velocity is a vector quantity that has both magnitude and direction. For one car, the direction is positive and for the other one the direction is negative.
Answer:
They are <em>directly proportional</em> to gravitational force.
Explanation:
Newton's Law of Gravity states that . The two "m" values are the masses of the objects, <em>r</em> is the distance between their centers, and G is the gravitational constant. Notice how the "m" values are in the fraction's numerator (i.e., on top)? That means <em>increasing</em> even one of the objects' masses will <em>increase</em> the gravitational force. This is known as a <em>direct relationship</em>.
Of course, you could always use the wonderful table provided to solve this! You don't believe what I wrote above? Take on of the two objects' masses, divide the gravitational force by that number, and see what happens. Multiply the two masses together, and see what happens. Prove it for yourself!
I hope this increases your understanding of this concept. Have yourself a wondrous day, 'kay?
