If something is traveling at 20 m/s constant speed AND its direction isn't changing, then its velocity is constant. Another way to say that is: Its acceleration is zero. Zero acceleration means zero NET force acting on the object, or a group of BALANCED forces acting on it, also called EQUILIBRIUM. The required answer is: YES.
If a real projectile is launched, the force of gravity acts on it vertically downward. There's no upward force acting on it to balance gravity. Therefore, the forces on the projectile are NOT balanced, there IS a net vertical force on it, and it's NOT in equilibrium. Too bad.
Answer:
Explanation:
We can solve this problem by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between its mass and its acceleration:
where
F is the net force on the object
m is its mass
a is its acceleration
In this problem:
F = 40 N is the force on the object
m = 2 kg is its mass
Therefore, the acceleration of the object is
Given what we know, we can confirm that the Earth pulls more strongly on the moon, option A is correct.
<h3 /><h3>Why does the Earth pull more strongly?</h3>
This has to do with the relationship between the mass of an object and its gravitational pull. These values are <u>directly proportional</u>, the more massive an object is, the stronger the gravitational pull that object exhibits. The moon does pull on the Earth as well, however, due to its smaller mass, it does not pull as strongly as the Earth on the moon.
Therefore, we can confirm that the Earth pulls more strongly on the moon, which means that option A is the correct choice for this question.

Answer:
C. means that the natural variation of the process must be small enough to produce products that meet the standard.
Explanation:
Process capability is the statistical measure of the inherent process variability of a given characteristics. we ca use a process capability study to assess the capability of a process to meet specification.
C. means that the natural variation of the process must be small enough to produce products that meet the standard.
