What is the acceleration of a 50kg object pushed with a force of 500 Newton’s
olasank [31]

Answer:

<h2>10 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{500}{50}  =  \frac{50}{5}  = 10 \\

We have the final answer as

<h3>10 m/s²</h3>

Hope this helps you

A diatomic molecule shares three pairs of electrons. What type of bond is present in the molecule? A single covalent bond becaus
VMariaS [17]
<h3><u>Answer</u>;</h3>

A triple covalent bond because each atom requires three more electrons to complete its octet.

<h3><u>Explanation</u>;</h3>
  • A triple covalent bond is a covalent bond formed by atoms that share three pairs of electrons.
  • For example;<em><u> in a diatomic molecule such a nitrogen; A nitrogen atom has five valence electrons, which can be shown as one pair and three single electrons. </u></em>When combining with another nitrogen atom to form a diatomic molecule, the three single electrons on each atom combine to form three shared pairs of electrons.

6. A solution of CuSO4 is electrolyzed for 10 minutes with a current of 1.5 amperes. What is the mass of copper deposited at the
vladimir2022 [97]

The mass of Copper deposited at the cathode : 0.296 g

<h3>Further explanation</h3>

Given

time = t = 10 min=600 s

current = i = 1.5 A

F = 96500 C

charge Cu=+2

Required

The mass of Copper

Solution

Faraday's Law

\tt W=\dfrac{e.i.t}{96500}

e = Ar/valence(valence Cu=2, Ar=63.5 g/mol)

Input the value :

\tt W=\dfrac{63.5/2\times 1.5\times 600}{96500}\\\\W=0.296~g
