Answer:
the waves in the sea, leaves of the trees, cables in the bridges, pendulum clock
Explanation:
In nature there are many examples of simple harmonic motion, for example.
* The movement of the waves in the sea is an oscillation movement up and down
* The movement of the leaves of the trees when a wind blows and then stops, but the leaf and branches are oscillating
* The movement of the cables in the bridges, especially in the suspension bridges
* The movement of a pendulum clock
Answer:
The angular acceleration of CD player is
.
Explanation:
Initial angular speed of a CD player is 0 and final angular speed is 41.8 rad/s. Time to change the angular speed is 3 s.
It is required to find the angular acceleration. The change in angular speed of the CD player divided by time taken is called its angular acceleration. It can be given by :

So, the angular acceleration of CD player is
.
Answer:
1.3 m/s
Explanation:
(300N of Fa + 100N' of Fa) - 140N of Ff /200Kg
400N of Fa - 140N* of Ff
260 of ∑F/ 200kg = acceleration
a of piano = 1.3 m/s²
D
The parent material refers the the rock that was responsible for the formation of a certain soil.
<u>Answer
</u>
A) Ice, water, steam
<u>Explanation
</u>
Ice is inform of a solid. Solids have particles that are tightly packed and they are in a regular pattern. For this reason they have the most ordered arrangement.
Water is a liquid. It has particles that are closely together but they are not in regular arrangement. For this reason they are next after ice.
Steam is in gaseous state. Gases have particles that are well separated with no definite arrangement. Hence they are the least in the order of molecule arrangement.
