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?
(3 x 10⁸ meter/sec) x (100 cm/meter) x (3.2 x 10⁷ sec/year)
= (3 x 10⁸ x 100 x 3.2 x 10⁷) (meter-cm-sec) / (sec-meter-yr)
= <span>( 9.6 x 10¹⁷ ) ( cm/yr )</span>
Answer:
The forces experienced by the middle particle are attractive, and the net force will remain the same (0) if and only if the distances of the sides particles to the middle particle are the same.
Explanation:
In example 20.3 the forces experienced by the middle particle are repulsive because all the particles are positive, for the case in which the particles on the sides are replaced for negative charge particles the forces experienced by the middle particle are attractive. Regarding the net force, because we don't know the distances we can not give a definitive answer, what we can say is that if the distances from the middle particle to the sides particles are the same the net force is zero for both cases (remain unchanged).
Answer:
1. s
2. m
3. start m/s
4. end m/s
5. m/s^2
Explanation:
1. t is the suffix for the time and it is related to seconds [s]
2. d is the suffix for distance and it is related to meters [m]
3. Vi is the suffix for the initial velocity and it is related to meters per second [m/s]
4. Vf is the suffix for the final velocity and it is related to meters per second [m/s]
5. a is the suffix for the acceleration and it is related to meters per squared second [m/s^2]
