Answer: Option (d) is the correct answer.
Explanation:
Electronegativity is defined as the ability of an atom to gain electrons in order to become stable.
When we move downwards in a group then there will be increase in size of atom. As a result, atomic radius will also increase.
Also, due to increase in size number of electrons will increase and hence, number of protons will also increase. Therefore, atomic mass will also increase.
Thus, we can conclude that elements change as you move down a column in a periodic table as the electronegativity decreases.

A. Energy
Explanation:
You can change energy from one form to another when you lift your arm or take a step. Energy is used to move matter. In this scenario, the matter would be you.
Answer:
1629 metres
Explanation:
Given that Carlos runs with velocity v = (5.6 m/s, 29o north of east) for 10 minutes.
To the north, the velocity will be:
V = 5.6 × sin 29
V = 2.715 m/s
Convert the time to second
Time = 10 × 60 = 600
Using the formula below
Velocity = distance/ time
Substitute all the parameters into the formula
2.715 = distance/600
Distance = 2.715 × 600
distance = 1629 m
