Answer:

The hydrogen ion in aqueous solution is no more than a proton, a bare nucleus. Although it carries only a single unit of positive charge, this charge is concentrated into a volume of space that is only about a hundred-millionth as large as the volume occupied by the smallest atom.

Answer:

At highest point vertical component of initial velocity becomes zero so at highest point the velocity of arrow will be

Vᵃᵗ ʰⁱᵍʰᵉˢᵗ = Vⁱⁿⁱᵗⁱᵃˡcosθ

= 15× cos30

= 15 × √3/2

= 6.99 ≈ 7 m/s

• Initial speed of arrow is 15 m/s.
• Angle of projection = 30°.

• Velocity at highest point?

• This is an example of GROUND-GROUND PROJECTILE.

We know that , acceleration due to gravity is applicable only along Y axis , hence the velocity component along X axis will always remain constant.

At highest point, the projectile only has the X component velocity (because Y component becomes zero).

[tex]v_{highest} = v \cos( \theta) [/tex]

[tex] \implies v_{highest} = 15 \times \cos( {30}^{ \circ} ) [/tex]

[tex] \implies v_{highest} = 15 \times \dfrac{ \sqrt{3} }{2} [/tex]

[tex] \implies v_{highest} = 12.99 \: m {s}^{ - 1} [/tex]

So, velocity at max height is 12.99 m/s
