Answer:
a
The total distance is 
b
The displacement is
Explanation:
From the question we are told that
Distance traveled by the ball for first player 
to the right
Distance traveled by the ball for second player 
to the left
The total distance traveled by the ball is mathematically represented as
Substituting values
The displacement is mathematically represented as
This is because displacement deal with direction and from the question we are told that right is positive and left is negative
Substituting values
Answer:
970.2 N
Explanation:
We are given that
Length of ladder=2.7 m
Mass,M=11 kg
Coefficient of friction=
Mass of painter=8M
Distance from base=d
We have to find the magnitude of the normal force exerted by the floor on the ladder.
Normal force exerted by floor on the ladder=
Where 
Normal force exerted by floor on the ladder=
A 14 pin dual-in-line IC package[14 DIL] is an integrated socket which is most popular form of IC package and has a wide range of application in digital electronics.
The 14-pin DIL has two pairs per side and each pair contains seven connecting pins.
The pairs of pins are arranged linearly one after another.The typical dimensions of width is 6.5 mm and the typical dimension of length is 18 mm.
we are asked to calculate the typical distance between two adjacent pins.
The typical distance between two adjacent pins is calculated as-
[ans]
We need to learn about median and mode because they are both important in statistical data and statistical data is what shows us important information about the world around us.
