Answer:
Correct answer: a = 15.46 m/s²
Explanation:
The formula for accelerated movement with the given data is:
V² - V₀² = 2 · a · d where the initial velocity V₀ and the final V
Since the initial velocity V₀ is zero, the formula is:
V² = 2 · a · d => a = V² / (2 · d) = 27.8² / (2 · 25) = 772.84 / 50 = 15.46 m/s²
a = 15.46 m/s²

Electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.
<h3>What is electricity?</h3>
Electricity is the movement or flow of negatively charged electrons through a suitable conductor where a charge is applied.
Moreover, magnetism is a natural phenomenon caused by the generation/movement of electric charges.
In conclusion, electricity and magnetism can be considered as part of the same phenomenon because both are generated by electromagnetic forces.

Answer:
W= 1812.6 J
Explanation:
Work (W) is defined as the scalar product of force F by the distance (d) the body travels due to this force.
W= F*d* cosα Formula ( 1)
Where:
F is the force in Newtons (N)
d is the displacemente in meters (m)
α : Angle formed between force and displacement
Data
F = 10 N
d = 200 m
α = 25°
Work done by the pulling force while the passenger walks 200 m
We replace data in the formula (1)
W= F*d* cosα
W= (10 N)*(200 m)* cos25°
W= 1812.6 (N*m)
W= 1812.6 J
