Answer:
It should fly 8° to west of south at 430km/h
Explanation:
According to the diagram. X components for both velocities must have the same magnitude in order to get the resultant velocity due south.
Solving for α:
α = 8.03°
Answer:
USING LAW OF CONSERVATION OF ENERGY

As we know that energy can not be created nor be destroyed.The pendulum cannot continue moving on its own because it meets energy losses due to friction.Its energy is converted into heat energy which dissipates in the air
Completing the square gives the answer right away.
which indicates a maximum height of 87 when

<h3><u>Answer;</u></h3>
<em>too small to be seen with an optical microscope </em>
<h3><u>Explanation;</u></h3>
- <em><u>An electron microscope is a type of microscope that is used to observe very tiny specimens whose features can not be observed by other types of microscopes.</u></em> It uses a beam of electrons to generate an image of a given specimen whose features can be clearly observed and studied.
- <em><u>Electron microscope has very high resolution and magnification as compared to other optical microscope </u></em>hence can be observed in the study of micro-organisms such as viruses which would be difficult to study their features using optical microscopes.
The answer is: The addition of a small dense nucleus at the center of the atom.
