Explanation

Directly eliminating physical distance and safety hazards removes the primary bottleneck preventing girls from attending secondary school.

Additional Information:

• [Access Barrier]  Long travel distances and unsafe routes are leading causes of female dropout in rural education systems.

• [Intervention Impact]   Providing reliable transport or localized facilities yields immediate improvements in enrollment and attendance rates.

Explanation

• Power is the dot product of force and velocity.
• The formula is P = F · v = Fv cosθ, where θ is the angle between force and velocity.
• When force and velocity act in the same direction, power is P = Fv.
• The SI unit of power is the watt (W), equivalent to one joule per second.

Explanation

• The slope of a momentum–time graph represents the rate of change of momentum.
• According to Newton's second law, the rate of change of momentum is equal to the net force acting on an object.
• The relationship is F = Δp / Δt, where p represents momentum and t represents time.
• A steeper slope indicates a greater net force, while a horizontal line indicates zero net force.
