<u>Answer:</u>
<u>air mass</u>
<u>Explanation:</u>
Remember, the weather of a particular location is often a description of the atmospheric condition of that particular place.
Indeed, the definition of an air mass fits the reporter's description above. As the name implies, <u>a particular air mass would represent the temperature characteristics of a particular area that has a constant or the same temperature and air pressure.</u>
Answer:
a)v=15.83 m/s
b)v=14.89 m/s
Explanation:
a)
In y direction

Given that h=35 m and initial velocity is zero.
So
t=2.67 sec
It means that rock hit water after 2.61 sec.
Given that player hears after 2.83 sec.
Δt=2.83 - 2.67 s
Δt=0.16 sec
So distance travel by sound wave
d= C x Δt
C= 343 m/s
d= 343 x 0.16
d=54.88 m
From diagram



x=42.27 m
Now
x = v x t
v=42.27/2.67
v=15.83 m/s
b)
Now sound speed have been changed
So new d
d=331 x 0.16
d=52.96 m
New x


x=39.75
So new velocity v
v=x/t
v=39.75/2.67
v=14.89 m/s
Answer:
neither be created nor destroyed
Explanation:
When we say charge is conserved, we mean that charge can neither be created nor be destroyed similar to energy concept.
When any physical quantity is conserved it always means that its quantity was, is and will remain the same throughout the eternity. It can neither be created nor be destroyed but it can change from one form to another.
