Answer:1. The masses Of The objects 2.the distance between the objects
Explanation:
newton's law of universal gravitation states that the force of attraction between two masses is directly proportional to the product Of The masses, and inversely proportional to thermal square Of The distance between them.therefore we can conclude that the two factors affecting the force between masses are:(1)the masses of the objects (2)the distance between the objects
Answer:
Explanation:
is the angle between the velocity and the magnetic field. So, the magnetic force on the proton is:
A charged particle describes a semicircle in a uniform magnetic field. Therefore, applying Newton's second law to uniform circular motion:
is the centripetal force and is defined as:
Here 
is the proton's speed and 
is the radius of the circular motion. Replacing this in (1) and solving for r:
Recall that 1 J is equal to 
, so:
We can calculate from the kinetic energy of the proton:
Finally, we calculate the radius of the proton path:
Explanation:
Remember that power is defined as how much Work is done per unit of time.
Work is defined as the amount of force applied across a certain distance.
Since in both cases of climbing the ladder (on Earth and the moon), Luke coveres the same amount of <em>distance </em>in the same amount of <em>time</em>, we are only left with one difference between the two cases - gravity.
If you were to carry your backpack on the moon with the same load of text books, it would take less force to pick it up on the moon. Therefore, Luke expends less effort on the environment with less gravity - the moon.
To find the difference factor - you would want to divid the gravitational contants between earth and the moon.

When the electric current moves through a wire, it makes a magnetic field. ... You can make a temporary magnet by stroking apiece of iron or steel (such as a needle) along with a permanent magnet.

Behaviorism is the aspect of psychology that believes that behavior is learned through rewards and consequences. There have been many scientific studies conducted on this idea.
