You used density, because water/ice has a density of 1, and ice will sink in anything with a lesser density
The tendency of a moving object to continue moving in a straight line or a stationary object to remain in place is called inertia.
According to law of inertia, an object maintains its state of rest or motion unless acted upon by an external force. an object can not move on its own unless force is applied on it to move it. also an object can not come to stop on its own unless acted upon by an external force to stop it.This is also known as newton's first law.
Answer:
23.246 metres per second
Explanation:
divide the speed value by 2.237
Answer: 0.1 m, 0.0583 m
Explanation:
We are given that:
Frequency for throat= 800 Hz
Frequency for mouth= 1500 Hz
Sound speed= 350 m/s
We have to find the corresponding lengths.
We have
f=
or L=
For the throat= L= = 0.1 m
For the mouth= L= = 0.0583 m
The answers are:
1. FALSE
2. FALSE
