Answer:

C. Remove 0.5 mL of liquid.

Explanation:

    When measuring the volume of a liquid with a graduated cylinder, you need to measure from the bottom of the meniscus (the curve).

    After observation, the volume of the liquid is 13 mL. Therefore, in order to get the desired volume of 12.5 mL, remove 0.5 mL of liquid.

A stream moving with a speed of 7.1 m/s reaches a point where the cross-sectional area of the stream decreases to one half of th
lana66690 [7]

Answer:

14.2 m/s

Explanation:

Given data:

Speed of the stream, v₁ = 7.1 m/s

let the cross section area at initial point be A₁

now area at the second point, A₂ = (1/2)A₁ = 0.5A₁

now, from the continuity equation, we have

A₁v₁ = A₂v₂

where, v₂ is the velocity at the narrowed portion

thus, on substituting the values, we get

A₁ × 7.1 = 0.5A₁ × v₂

or

v₂ = 14.2 m/s
