Answer:
Potential energy of the object will be equal to mgh
Explanation:
Let the mass of the object is m
Acceleration due to gravity is 
Let the object is released from height h
We have to find the potential energy
Potential energy is of an object released from height h is equal to
, here m is mass, g is acceleration due to gravity and h is height from which object is released.
The right answer for the question that is being asked and shown above is that: "A. Reverse the way the wire is connected to the poles of the battery." the statement describes a step that will help troubleshoot and work toward the solution of this problem is that <span>Reverse the way the wire is connected to the poles of the battery.</span>
Yes. Displacement is a vector, as opposed to distance, which is a scalar. Since displacement is a vector quantity, the negative sign represents direction. As with velocity and acceleration, it just comes down to how you define your coordinate system
Answer:
let current flow be x
Explanation:
than we know potential difference = energy supply / charge then 120 = 10 /x then x=12 therefore pd = 12 v
V = 20 m/s
Ecin = 1.8 x 10^5 J
Ecin = m*v^2/ 2
1.8*10^5 = m*400/2
200m = 1.8*10^5
I know you can do it :)
