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
<h3>Longitudinal Waves:</h3>
- Longitudinal waves are waves in which particles moves in the direction parallel to the direction of wave.
- Longitudinal wave are one directional waves.
- Sound waves and tension force applied on spring are examples of longitudinal waves.
<h3>Transverse Waves:</h3>
- Transverse waves in which particles move perpendicular to the direction of wave propagation.
- Transverse wave are two directional waves.
- Ripples formed on water and all electromagnetic waves are examples of transverse waves.

Explanation:
the first 35 to 40 acceleration will be 5 same as 40 to 45 ,
5+5=10
Answer:
All these statement are true
Explanation:
Gravity will be acting like a centripetal force for the circular motion of object around earth, which makes it perpendicular to the velocity vector. In the case of elliptical motion, gravity can still be divided into 2 vectors, one parallel and the other perpendicular to the velocity. At the nearest point in elliptical motion, gravity is directly perpendicular to velocity just like in circular motion. At the farthest point, the potential energy is minimized and has been converted into kinetic energy. Therefore at this point the speed is greatest.
