The given data is Magnification, M = 15
Length of the tube , L = 16 cm
The focal length of the lens can be calculated by:
M = L/F
Substituting the value, we get:
15 = 16/f
f = 16/15
f = 1.067 cm
Using the equation of magnification we get,
M = v/u
Substituting the values we get:
15 = v/u
v = 15 u
With the help of lens formula, calculate the object distance:
1/f = 1/v + 1/u
Substituting the value we get,
1/1.067 = 1/15u + 1/u
0.937 = 1.067/u
u = 1.13 cm or 1.1 cm.
Hence, the object distance is 1.1 cm.
Answer:
Explanation:
metal can become magnetic if they have many spinning electron. When the majority of atoms spin in the same direction the strong magnetic field is produced the direction of electron spin determine the direction of magnetic field

Answer:
Corrigiendo el error de Schwann y preparando el principio de Virchow, señaló que las células se multiplican por escisión de su núcleo, no por generatio aequivoca a partir del protoplasma originario. ... Según los historiadores Pagel (1945) y Ackerknecht (1957), parece que Remak precedió a Virchow en sus descubrimientos.

Answer:
The cell
Explanation:
<em>The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is </em><em>the cell.</em>
This is in accordance with the cell theory which has three basic components, including:
1. The cell is the basic unit of life
2. All living organisms are made up cells
3. Cells arose from pre-exsiting cells.
<u>Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.</u>
