Once it leaves the circle, it'll continue in a straight line, in the direction it was moving when it left the circle.
B) ohm,s law :electrons moving through a conductor yo create a circuit
Answer:
Total displacement = 0
Explanation:
He lives his front porch and still returns to his front porch.
Now, displacement is a vector quantity and as such, it is the distance between the initial point of movement and the final point of movement.
In this case the initial point is the same as the final point and thus the displacement is zero.
Explanation:
Sum the moments about the hinge H. Assume anticlockwise is positive and clockwise is negative.
∑τ = Iα
(20 N) (500 mm) − F (120 mm) = 0
F = 83 N
Pressure = force / area
P = 83 N / 0.0036 m²
P = 23,000 Pa
Answer:
The formula for calculating Density is:
= Mass / Volume
From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.
If mass however was decreasing, density would have to decrease as well.
For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.
Density of 5kg brick = 5 / 5 = 1 kg/m³
Density of 10kg brick = 10 / 5 = 2kg / m³
Density of 15kg brick = 15 / 5 = 3 kg /m³
<em>Notice how density increases as mass increases and decreases when mass decreases. </em>
