Answer:
Step-by-step explanation:
Given sin²∅ + sin∅ = 1, we are to find the value of sin²∅ + sin⁴∅. ... 2
From sin²∅ + sin∅. = 1; sin²∅ = 1 - sin∅. ... 3
Substitute equation 3 into 1
sin²∅ + sin⁴∅
= sin²∅ + (sin²∅)²
= (1 - sin∅)+( 1 - sin∅)²
open the parenthesis
= 1 - sin∅+ (1-2sin∅+ sin²∅)
= 1 - sin∅+ 1-2sin∅+ sin²∅
= 1+1-sin∅-2sin∅+sin²∅
= 2 - 3sin∅+sin²∅
Since sin²∅ = 1 - sin∅, the resulting equation becomes;
= 2 - 3sin∅+(1 - sin∅)
= 2 - 3sin∅+1-sin∅
= 3-4sin∅
Given : 
Multiplying and Dividing with (3 - 4i)
We know that i² = -1
Option D is the Answer
I think its 24% because .24 x 50 is 12 but I could be doing it wrong, sorry I can't say for sure.
It is <span> n = -14 i believe</span>
Answer:
B. increase by a factor of 3.
Step-by-step explanation:
According to ohms law:
V ∝ R
Vo = IoR
R = Vo/Io ... (1)
Vo is the initial potential difference/voltage
Io is the initial current across the resistor
R is the resistance
If for an Ohmic conductor, we triple the voltage without changing the resistance:
New voltage V1 = 3Vo
New voltage V1 = I1R (resistance doesn't change)
I1 is the current after the voltage has tripled
3Vo = I1R
R = 3Vo/I1... (2)
Equating both resistances in 1 and 2 since resistance doesn't change we have:
Vo/Io = 3Vo/I1
1/Io = 3/I1
I1/Io = 3
New current I1 = 3Io
This shows that tripling the voltage increases the current by factor of 3
