Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.

Explain the measures that can be taken to ensure safety in a storm.
Rufina [12.5K]
If your in a city, go inside a building immediately. most buildings have lightening rod, so the lightening voltage won't hit on you.
if you're in an open area, don't go under a tree, or it'll hit you and the tree, even if it doesn't hit you, you still cannot take the impact by the exploding tree. leave the water or metal bicycle or stuff that conducts electricity.

What is the ph of an aqueous solution with the hydronium ion concentration : [h3o+] = 3 x 10-5 m ?
BaLLatris [955]

The concentration of hydrogen can be shown as:

[H+ ] = 3 * 10-5 M

pH can be determined as:

pH = - log [H+ ]

= - log (3 * 10-5)

= 4.53

Thus the pH of solution is 4.53
