Hydrogen/hydronium ion concentration

Physics
1 answer:
Valentin [98]3 years ago
5 0

Answer:

Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration. So the pH is the -log of the [hydronium ion].

3. In 1989, Michel Menin of France walked on a tightrope suspended under a
Tamiku [17]

Answer: 80m

Explanation:

Distance of balloon to the ground is 3150m

Let the distance of Menin's pocket to the ground be x

Let the distance between Menin's pocket to the balloon be y

Hence, x=3150-y------1

Using the equation of motion,

V^2= U^s + 2gs--------2

U= initial speed is 0m/s

g is replaced with a since the acceleration is under gravity (g) and not straight line (a), hence g is taken as 10m/s

40m/s is contant since U (the coin is at rest is 0) hence V =40m/s

Slotting our values into equation 2

40^2= 0^2 + 2 * 10* (3150-y)

1600 = 0 + 63000 - 20y

1600 - 63000 = - 20y

-61400 = - 20y minus cancel out minus on both sides of the equation

61400 = 20y

Hence y = 61400/20

3070m

Hence, recall equation 1

x = 3150 - 3070

80m

I hope this solve the problem.

Help me answer these, please. I GIVE CROWNS!! PLEASE!!

Answer: 1- A diagram showing the forces acting on the object.

2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.

3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.

4- I don’t know

5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces

6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.

7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.

8- Imbalance or unequal force

9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.

10- net force is the vector sum of all the forces that act upon an object.
