Answer:
The ball will fly tangential to the original circle
Explanation:
The image here is missing, however we can still answer to the question.
In fact, the circular motion of the ball when it is tied to the rope is a combination of two separate effects:
1- The centripetal force, in the form of the tension in the rop, that pulls the ball at any time towards the centre of the circular path
2- The inertia of the ball, which tends to continue its motion in a straight direction, tangential to the circle and perpendicular to the direction of the centripetal force
When child let the string go, there is no more tension in the string acting on the ball, and therefore, there is no longer a centripetal force.
As a result, number 1) disappears, and therefore there is only the inertia of the ball that will determine its motion: and therefore, the ball will continue its motion straight in a direction tangential to the original circle.
There are three perfect squares in a standard die; 1, 2, 4. If there is two standard dies, then the probability of getting a perfect square is 1/3 x 1/3 = 1/9.
There are 4 numbers less than 5 in a standard die, making it 1/4 x 1/4=1/16.
It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.
The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions. The higher the electron affinity is, the more the neutral atom wants to gain electrons. The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell. That means that they want to form cations (loose electrons). Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration. That means that it forms anions.
I hope this helps. Let me know if anything is unclear.
