Answer:
162500000.
Explanation:
Given that
Diameter of the wire , d= 1.8 mm
The length of the wire ,L = 15 cm
Current ,I = 260 m A
The charge on the electron ,e= 1.6 x 10⁻¹⁹ C
We know that Current I is given as
I=Current
q=Charge
t=time
q= I t
q= 260 m t
The total number of electron = n
q= n e
n=162500000 t
The number of electron passe per second will be 162500000.
I pretty sure that 3 is b and 4 is A and 5 I need a full picture
Subjective questions can be answered most likely through well-designed scientific investigations. Investigating peoples opinions or favorites does not involve any scientific investigations.
<h3>What are scientific investigation?</h3>
Scientific investigations include study on different natural phenomenon through well designed research methodologies. They include a preliminary hypothesis based on observations and various scientific records helps for reference.
Through well designed scientific experiments we can solve subjective questions and can be helpful in solving different environmental or social issues.
Peoples opinion or objective types questions are not targeted at scientific investigation, hence, option b is correct.
