Answer:
The magnitude of acceleration is 3 m/s^2.
Explanation:
The net force along North-South direction is 18-24=-6 N.
The net force along East-West direction is 16-16=0 N
The net magnitude of force is square root of (-6)^2+0^2 which is 6 N.
By Newton's Second law,
Force F=ma
Therefore acceleration a=F/m
a=6/2
a=3 m/s^2

The answer is 500 A/sec.
N=10 ; Solensid; L=4 m H ; 
So, 500 A/sec.
What is Solensid?
- Electromagnets are magnets in which the wire is coiled around an iron core. When an electric current is applied to the iron core, a magnetic field is formed around it. When the power is turned off, the magnetic field dissipates. The wire-wound core of the magnet is ferromagnetic or ferrimagnetic in nature. The most prevalent material utilised in the core is iron.
- The magnetic field created is governed by the availability of power. A permanent magnet does not require electricity, and its magnetic field cannot be changed. Solenoid, MRI machines, hard drives, relays, motors, loudspeakers, and generators all employ electromagnets.

If an airplane is flying at 300 km/h to the east and is facing a headwind of 18.0 km/h, the final velocity can be calculated using simple vector addition. In this case, the planes velocity is positive (+330 km/h) and head wind has a negative component (-18.0 km/h). Vector addition yields +330 km / h + (-18.0 km /h) = 312 km / h.
Answer: the refraction of light by the atmosphere
Explanation: Refraction is the phenomenon in which there is a change in direction of light passing from one medium to another or from a gradual change in the medium.
Here in case of sunset, the sun rays passes through the varying density of atmosphere because of varying concentrations of dust particles.
Reflection is the phenomenon in which the light bounces back after falling on a surface.
Absorption is the phenomenon in which matter captures the electromagnetic radiations and thus the energy of photons is converted to internal energy of the system.
