An Ohm or a electrical resistance is a measure of the amount of electrical energy transferred by an electric charge as it moves from one point to another circuit. The voltage between two points in a circuit can be measured with a voltmeter.
Answer:
rust is formed when these two combine in the air
Explanation:
Answer:
a.)
b.) 5 blocks
Explanation:
Let's find the volume of the metal block:
Now, let's find the volume of the smaller blocks:
So, one small block has a volume of 8cm. If the volume of the larger block is 40cm, we can fit a total of 5 smaller blocks into the larger block, meaning it will make up the same volume.

Let's apply an equation of equilibrium to the situation: The sum of the moments about the left end of the board must equal 0.
We have three moments to add. Positive force values indicate upward direction and negative values indicate downward direction. All distances given below are measured to the right side of the left end of the board:
- The weight of the board, -125N, located at 2m (center of the board due to its uniform density)
- The tension in the right chain, +250N, located at 4m
- The weight of the person, -500N, located at a distance "x"
The sum of the moments must equal 0 and is given by:
ΣFx = 0
F is the magnitude of force, x = distance from the left end of the board
Plug in all of the force and distance values and solve for x:
ΣFx = 250(4) - 125(2) - 500x = 0
500x = 750
x = 1.5m
