Answer:
b.They will display similar chemical and physical properties.
Step-by-step explanation:
We have to find about the elements that are in the same group.
In modern periodic table
Elements are arranged in group according to similar properties.
The elements which have same properties are placed in the same group and mass of different elements are different in the group.
The outer electronic configuration of every element in the same group are same.
Therefore, the physical and chemical properties of the elements are same in the group.
Hence, option B is true.
Answer:b.They will display similar chemical and physical properties.
12.8, 11.6, 10.4, 9.2, 8.0, 6.8, 5.6
3, 1.5, 0.75, 0.375, 0.1875, 0.09375, 0.046875
The first one is arithmetic as the pattern is deducting 1.2, second one is geometric as it is dividing 2.

3. Needs Question 2 to Answer
1. 115÷5=23
2 seconds
At max height, velocity = 0
u = 64 feet/sec
v = 0
a = -32
t = ?
v = u + at
0 = 64 - 32t
32t = 64
t = 2
