The volume of the diluted (i.e the new) solution given the data is 147 mL
<h3>Data obtained from the question </h3>
- Molarity of stock solution (M₁) = 1.85 M
- Volume of stock solution (V₁) = 84 mL
- Molarity of diluted solution (M₂) = 1 M
- Volume of diluted solution (V₂) = ?
<h3>How to determine the volume of diluted solution </h3>
M₁V₁ = M₂V₂
1.75 × 84 = 1 × V₂
V₂ = 147 mL
Thus, the volume of the new solution is 147 mL

-- Kinetic energy is the energy of mass in motion. The amount is determined by the mass of whatever is moving, and its speed.
-- Potential energy is the energy that's stored up in some form, not being used yet but ready to be used when you want it.
For example, one form of it is <u><em>chemical</em></u><em> </em>potential energy, like in a battery, or a match. You get the energy out of a battery when you connect it to a motor or a light. You get the energy out of as match when you make the tip hot and it flares up.
This question is asking about <u><em>gravitational</em></u> potential energy. An object has stored energy just by being up high, like a bowling ball on a shelf. You get the energy out of it just by dropping it ... possibly enough to crack the floor !
The amount of this kind of potential energy is determined by the mass of the object, and how high up it is.
-- Getting the answers from other people doesn't help you a bit, until you understand them and can answer the question on your own.
Answer:
Frictional force increases with the increase in the roughness of the surface.
Explanation:
You will see that the rougher the surface, the greater the wear and tear.
The answer is 2.93m (to 2 dp)
