Answer:
a single closed path of electrical components including a voltage source
Answer:
The ball reaches Barney head in 
Explanation:
From the question we are told that
The rise velocity is 
The height considered is 
The horizontal velocity of the large object is 
Generally from kinematic equation

Here s is the distance of the object from Barney head ,
u is the velocity of the object along the vertical axis which is equal but opposite to the velocity of the helicopter
So

So

= 
Solving the above equation using quadratic formula
The value of t obtained is 
<span>When melting and snow accumulation are equal.</span>
C is incorrect because the atomic number and symbol are the only ones displayed.
I think it could be A but it is most likely C
Hope it helps!!
