Decibels I believe? I’m not 100% sure
Answer:
216 m
Explanation:
Assuming a straight line:
Δx = vt
Δx = (12 m/s) (18 s)
Δx = 216 m
Charles's <span>law is also known as the law of volumes explained the relation between the volume of gas and its temperature.
Charles's law states that: " At constant pressure, the volume of a certain mass of gas is directly proportional to its temperature in kelvin".
This means that:
V = T*constant
V/T = constant
Based on this, the correct choice is:
</span><span>a) V/T</span>
Answer:
(-1.5,-1.5)m
Explanation:
we know that:
where 
is the location of the center of gravity in the axis x, 
is the mass of the object i and 
the first coordinate of center of gravity of object i.
so:
Where 
is the first coordinate of the center of gravity for the fourth object.
Therefore, solving for , we get:
At the same way:
where 
is the location of the center of gravity in the axis y, is the mass of the object i and 
the second coordinate of center of gravity of object i. replacing values we get:
Where 
is the second coordinate of the center of gravity for the fourth object.
solving for :
It means that the object of mass 8kg have to be placed in the
coordinates (-1.5,-1.5) m.
I’m pretty sure it’s ground but I might be wrong. Sorry
