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

Which type of reaction is the Haber process: N2(g) + 3 H2(g) → 2 NH3(g) + heat? *
Alik [6]

Answer:

exothermic, with a decrease in entropy

Explanation:

Whenever you produce heat as a product in a reaction, the reaction is exothermic. To determine entropy, we know we have 4 moles of gas on reactant (1 from N2 and 3 from H2) and in produce side we only have two moles (2 from NH3) thus since we are decreasing the number of gas molecules, there is going to be less disorder, hence decrease in entropy.
