Answer:
λ = 4.59 ×10⁻³ nm
Explanation:
Given data:
Energy of light = 4.33 ×10⁻¹⁴ J
Wavelength of light = ?
h = 6.626×10⁻³⁴ js
c = 3×10⁸ m/s
Solution:
Formula:
E = hc/λ
4.33 ×10⁻¹⁴ J = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / λ
λ = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / 4.33 ×10⁻¹⁴ J
λ = 19.878 ×10⁻²⁶ Jm / 4.33 ×10⁻¹⁴ J
λ = 4.59 ×10⁻¹² m
λ = 4.59 ×10⁻³ nm
16 cells are produced from a single parent cell after the fourth division of the cell.
<h3>What is a cell?</h3>
In biology, the smallest unit can live on its own and that makes up all living organisms and the tissues of the body.
In mitosis type of cell division, one parent cell is divided into two same or different daughter cells. In this way, in the first division, two cells are produced from single parent cells and in the second division, four daughter cells are produced. In the third division, 8 cells are produced from 4 parent cells and in the fourth division, 16 cells are formed from 8 cells.
So we can conclude that 16 cells are produced from a single parent cell after the fourth division of the cell.

Answer:
a. 1/3
In the picture- D. 4
Explanation:
The product of the gradients of perpendicular lines =-1
m1m2=-1
Given an equation of a line in the form y=mx+c, m is the gradient of the line.
For y= -3x-9, m=-3
m1m2=-1
-3×m2=-1
m2=1/3
The gradient of the perpendicular line is 1/3
For the question in the picture, y=-1/4x-9, m=-1/4
m1×m2=-1
-1/4m2=-1
m2=4
The slope of the line perpendicular to y=-1/4x-9 is 4
