Answer:
Explanation:
From the question we are told that
The mass of the collar is 
The original length is 
The spring constant is 
Generally the extension of the spring is mathematically evaluated as
Now with Pythagoras theorem we can obtain the length from A to B as
The extension of the spring at B is
According to the law of energy conservation
The energy stored in the spring at point A + the kinetic energy of the spring = The energy stored on the spring at B
So
substituting values
=>
Answer:
A convex mirror is a diverging mirror (f is negative) and forms only one type of image. It is a case 3 image—one that is upright and smaller than the object, just as for diverging lenses.
Explanation:
hope this helps have a good night :)
V = I R
12 = I x 4
I = 12 ÷ 4 = 3 A
In a series circuit the total current is the same throughout resistors and so:
The voltage is distributed throughout the resistors and so:
and the total resistance can be calculated by adding up the resistors resistance:
First thing is to calculate the total resistance and so:
And by Omh's law V=IR we have:
And so the total current of the circuit is 1.2 amps i.e. 1.2 A.
I'd say C to avoid situations in which alcohol is present and remain alcohol free
Refusal skills help people, most likely children it helps them avoid participating in risky behaviors and choices. such like alcohol in this case
Refusal skills Helps them resist peer pressure and help them make right choices
Hope that helps alrighty bye now!
