One newly schools question and answer inquired students to say what they consider is the most crucial important point for a student to do in order for you to achieve success. Of the many reactions, one that that stood out was practice. People who are definitely successful do not become successful by being born. They work hard and commitment their lives to succeeding. This is how you can complete your goals. in this article, some question and answer examples that you can easily make use of to develop your knowledge and gain insight that will help you to sustain your school studies.
An ionized calcium atom has a charge of +2elementary charges. If this ion is accelerated through
a potential difference of 2.0 x 103 volts, the ion’s
change in kinetic energy will be
The change in the kinetic energy of the calcium ion’s is 6.4 x 10⁻¹⁶ J.
Change in Kinetic energy of calcium atom
The change in the kinetic energy of the ion’s which accelerated through the given potential difference is calculated as follows;
ΔK.E = qV
- ΔK.E is the change in kinetic energy
- q is the charge of the ion
- V is the potential difference
Substitute the given parameters in the above equation and solve for change in kinetic energy.
ΔK.E = (2e)V
ΔK.E = (2 x 1.6 x 10⁻¹⁹) x (2.0 x 10³)
ΔK.E = 6.4 x 10⁻¹⁶ J
Thus, the change in the kinetic energy of the calcium ion’s is 6.4 x 10⁻¹⁶ J.
From the answer and question examples above, hopefully, they could simply guide the student sort out the question they had been looking for and keep in mind of every thing declared in the answer above. Then possibly will make some sharing in a group discussion and also learning with the classmate with regards to the topic, so another student also take up some enlightenment and still keeps up the school learning.
