Light bulbs, think about parallel circuits as something you plug into, so for example you plug in a tv for it to work, same with a refrigerator and Christmas lights
Answer:
The boat speed relative to the riverbank is 2.96 m/s
Explanation:
The boat move to the north at 2.7 m/s across the river and the river current is 1.2 m/s to the west, therefore the direction of the boat is perpendicular to the river (90).
The boat speed vb = 2.7 m/s
The current speed vc = 1.2 m/s
The formula to calculate the speed of the boad relative to the riverbanks (Vbc), as follow
vbc =
=
since cos 90 = 0, hence
vbc =
= 2.96 m/s
Answer:
The distance from charge 5 μ C = 26.45 cm and the distance from - 4 μ C is 23.55 cm.
Explanation:
Given that
q₁ = 5 μ C
q₂ = - 4 μ C
The distance between charges = 50 cm
d= 50 cm
Lets take at distance x from the charge μ C ,the electrical field is zero.
That is why the distance from the charge - 4 μ C = 50 - x cm
We know that ,electric field is given as
Therefore the distance from charge 5 μ C = 26.45 cm and the distance from - 4 μ C is 23.55 cm.
Assuming that the collision is inelastic that is they are stuck together after the collision, momentum is conserved. We can determine the final velocity of the final mass as follows:
m1v1 + m2v2 = m3v3
100(4) + (200)(-3) = (300)v3
v3 = -0.6667 m/s
Therefore, the final mass moves at 0.6667 m/s to the left.
i believe the answer would be C.
Hope this helps!
