Answer:
The ball is making a circular motion. The centripetal acceleration in a circular motion is
~
Explanation:
Normally in physics questions like this, we use all the information in the question. Here, we left out the mass or the height of the object. I assume there is more sub-questions that is not shared here. However, the centripetal acceleration can be found by using the velocity and the radius only.
Answer:
IMA = 2
Explanation:
Given the following data;
Resistance gear = 54 teeth
Effort gear = 23 teeth
To find the ideal mechanical advantage (IMA);
IMA = number of teeth on the resistance gear/number of teeth on the effort gear
Substituting into the equation, we have;
IMA = 54/23
IMA = 2.35 ≈ 2
Therefore, the ideal mechanical advantage (IMA) of this two-gear system is 2.
If U-235 is used a characteristic would be a massive explosion.
The nucleus splits, creating two atoms who's combined mass is equal to the original atom's.
You start with one element, and end up with two different ones.
