Chemistry
1 answer:
charle [14.2K]2 years ago
8 0

Answer:

<h2>The answer is 4 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

where

a is the acceleration

f is the force

m is the mass

From the question

f = 20 N

m = 5 kg

We have

a =  \frac{20}{5}  \\

We have the final answer as

<h3>4 m/s²</h3>

Hope this helps you

algol [13]

Answer:

The voltage or potential difference

Explanation:

What makes current flow in a circuit is the voltage or the potential difference.

This force is supplied by the battery or the mains electrical circuit.

  • Every circuit requires the voltage to drive current through
  • When a circuit is complete, the battery is able to overcome any resistance by the generating enough voltage which is the force to drive the current through.

What is the difference between concentrated acid and a weak one?
makkiz [27]

Answer:

Difference between concentrated acid and weak acid :---

  • According to Arrhenius's theory the substances which easily get dissociated into H+ ions when dissolved in water are acids.

  • And the substance which readily gives H+ ions on dissociation (when dissolved in water) are Strong Acid. Examples are HCl , H2SO4 etc.

While,

  • Concentration of acid is just the value of pH. pH is the measurement of concentration of acid or base. The lower the pH, higher the concentration.

  • So strong acid is strong because it gives H+ ions readily in water and Concentration is the value of pH.
