The distance of the object from the lens is 3.12 cm.
<h3>What is magnification?</h3>
Magnification is the process of of enlarging an apparent size of an object.
<h3>Object distance</h3>The object distance is calculated using the following lens formula;
where;
- M is the magnification
- V is the image distance
- U is object distance
Thus, the distance of the object from the lens is 3.12 cm.

Answer:
orbital speed of the electrons in their orbit will increase
Explanation:
As we know that centripetal force for electrons will be due to electrostatic attraction force of electron.
So it is given as
so we have
now on the left side if the force of attraction will increase and hence there must be the change in that part of equation
So here at the same position the speed of the electron
So we can say that correct answer will be
orbital speed of the electrons in their orbit will increase
Answer: (-4.3, 2.5)
Explanation:
In the second quadrant, magnitude of the vector is 5 and angle is 30° from the negative x-axis.
We can write this in terms of its components:
Thus, the components of vector in the second quadrant are (-4.3, 2.5)
