Substances become neutral at the number 7 because at this point, the acid and Base are equal and becomes neutralized
Answer
Given,
Current, I = 14.6 A
magnetic force per unit length = 0.119 N/m
Magnitude of magnetic field = B = ?
a) F = ILB sin θ
θ = 90°
So,
b) The direction of magnetic field is in +z direction.
Higher frequency,higher energy,shorter wavelength
Answer:
0.5 hours or 30 minutes
Explanation:
each hour travels 80km
so, time taken= 40/80 hours
= 0.5 hours
= 30 minutes
