The value of the object distance at which the lens will act as a simple microscope is 25 cm.
<h3>What is the least distance of distinct vision?</h3>
The least distance of distinct vision is the smallest distance someone with "normal" vision can comfortably look at something.
The least distance of distinct vision of a microscope is 25 cm.
When the object is placed at focal length of 15 cm, a virtual, erect and magnified image will be formed at near point (D = 25 cm) from the eye.
Thus, the value of the object distance at which the lens will act as a simple microscope is 25 cm.

This is somewhat confusing, but I'd have to go with A. Since Newton's Third Law states that every action has an equal but opposite reaction.
Answer: Bohr's model
Explanation:
The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.
The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.
The acceleration is 1.67 m/s²
<u>Explanation:</u>
Given:
Speed, s = 60km/hr
s =
m/s
s = 16.67 m/s
Time, t = 10 seconds
Acceleration, a = ?
We know:
![Acceleration = \frac{speed}{time}](https://tex.z-dn.net/?f=Acceleration%20%3D%20%5Cfrac%7Bspeed%7D%7Btime%7D)
On substituting the value, we get:
![a = \frac{16.67}{10} \\\\a = 1.67 m/s^2](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B16.67%7D%7B10%7D%20%5C%5C%5C%5Ca%20%3D%201.67%20m%2Fs%5E2)
Therefore, the acceleration is 1.67 m/s²
Power = energy / time
Multiply each side by 'time', then
divide each side by 'power':
Time = energy / power
Time = 432 / 75 = <em>5.76 seconds</em>
