Answer:
is weaker than the electromagnetic force
Explanation:
The weak force or weak nuclear force acts between elementary particles.
Weak nuclear force is important in the reaction speed of some nuclear reactions that occur in stars. It is also present at the origin of volcanic explosions.
The weak force is a short-range force, less than a billionth of a millimeter: 10-13mm. At a greater distance, the intensity of this force is already negligible.
If the weak force had a value of 1,
the electromagnetic force would have a value of 1,000
and the strong force would be worth 100,000,000,000
Although it is vastly weaker than the other two nuclear forces, the weak force is important in that it enables the Sun and stars to produce light and energy.
The weak force causes a type of radioactive decay called "beta decay." An example of beta decay is the decay of the neutron when it becomes 1 proton + 1 electron + 1 neutrino
Answer:
The total resistance is 750 [ohm]
Explanation:
To solve this problem we must remember that when we have resistors connected in series, these are added each by the resistance value, in this way we have:
Rt = 15 * 50 = 750 [ohm]
The mechanical advantage of a machine is the ratio between the output force and the input force:
In our problem, the input force is 100 N, while the output force is the weight of the object the student lifts, 500 N. So, the mechanical advantage is
Answer:
I would say a pond
Explanation:
A pond is more still than an ocean, therefore you could see your reflection better
