A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?
AlexFokin [52]

Answer:

<h2>15 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}  \\

f is the force

m is the mass

From the question we have

a =  \frac{300000}{20000}  =  \frac{30}{2}  \\

We have the final answer as

<h3>15 m/s²</h3>

Hope this helps you

A student has 0.75 L of a 5.0 M solution and dilutes it to make 3.5 liters. What’s the molarity of the diluted solution?
Marianna [84]

The molarity of the diluted solution : 1.1 M

<h3>Further explanation</h3>

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

\tt n_1=n_2\\\\M_1.V_1=M_2.V_2

M₁ = Molarity of the solution before dilution  

V₁ = volume of the solution before dilution  

M₂ = Molarity of the solution after dilution  

V₂ = Molarity volume of the solution after dilution

M₁=5

V₁=0.75

V₂=3.5

\tt M_2=\dfrac{M_1.V_1}{V_2}\\\\M_2=\dfrac{5\times 0.75}{3.5}\\\\M_2=1.07\approx 1.1

galben [10]

Answer:

The atomic model started out as a large single ball, then with electrons attached to it. It then became  "planetary model" with electrons orbiting at specific levels, and then later one with a nucleus or multiple different particles like protons and neutrons, and electrons orbiting at general (but not specifically predictable) areas.

Explanation:

thank u :)
