Answer:
14 m/s
Explanation:
The motion of the book is a free fall motion, so it is an uniformly accelerated motion with constant acceleration g=9.8 m/s^2 towards the ground. Therefore we can find the final velocity by using the equation:
where
u = 0 is the initial speed
g = 9.8 m/s^2 is the acceleration
d = 10.0 m is the distance covered by the book
Substituting data, we find
Maybe for the first the hand because there are so many joints that do so many movements and functions.
For the second, the tongue because there are so many taste buds that need to sense and taste and move.
I hope that helps, that's what I remember from elementary school. XD
<h3><u>Answer;</u></h3>
B. 3.43 kPa
<h3><u>Explanation</u>;</h3>
Pressure is given by the formula;
Pressure = Force / Area
Force is the product of mass and acceleration due to gravity.
Thus; Force = mass x acceleration due to gravity
Substituting;
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, using the first equation;
Pressure = 3430 N / 1m² or Pa
<h3> <u>= 3.43 kPa</u></h3>
Answer:
130m
Explanation:
You just have to multiply velocity by the time traveled:
100m/s * 1.3s = 130m!
