Answer:

The solution becomes more acidic.

Explanation:

As the pH of a solution decreases, the concentration of hydrogen ions [H+] increases. Acidic solutions have a higher concentration of hydrogen ions and a lower pH.

I hope this helped. :)

Drawing a shows a displacement vector (450.0 m along the y axis). In this x, y coordinate system the scalar components are Ax 0

Alisiya [41]

Answer:

x ’= 368.61 m, y ’= 258.11 m

Explanation:

To solve this problem we must find the projections of the point on the new vectors of the rotated system θ = 35º

x’= R cos 35

y’= R sin 35

The modulus vector can be found using the Pythagorean theorem

R² = x² + y²

R = 450 m

we calculate

x ’= 450 cos 35

x ’= 368.61 m

y ’= 450 sin 35

y ’= 258.11 m

An icicle falls off of a skyscraper from rest and falls for 34 seconds. How fast will that icicle be moving after that time? Sho

Answer:

The icicle will be moving at 333.54 m/s

Explanation:

Free Fall Motion

A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not encounter air resistance.

If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is $g = 9.81 m/s^2$ .

The final velocity of a free-falling object after a time t is given by:

vf=g.t

The icicle falls from rest for 34 seconds. We need to find the speed after that time:

vf = 9.81*34

vf = 333.54 m/s

The icicle will be moving at 333.54 m/s
