Answer:
Magnetic field experienced = 4.5 × 10⁻⁴ T
Explanation:
The magnetic field around an infinite straight current-carrying wire at a distance r from the wire is given by
B = (μ₀I)/(2πr)
B = ?
I = 20 KA = 20000 A
r = 8.9 m
μ₀ = magnetic permeability = 1.257 × 10⁻⁶ T.m/A
B = (1.257 × 10⁻⁶ × 20000)/(2π×8.9) = 4.5 × 10⁻⁴ T
Answer:
Final velocity = 16 m/s
Total distane travelled = 390 m
Explanation:
We can use equation of motion to solve this:


Answer:
2.At the end of meiosis, there are four cells each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.
The time it takes for a point to reach 0 displacement from maximum displacement is

of a cycle. Thus, one period (

) will take

.
The frequency is simply

.
The speed is given by:
