A. Parallel circuit
Short circuits are circuits that is like plugging in a USB into your computer and the other end to your iPhone, so it's not D.
Series circuits can come in all kinds of different shapes, so it's not C.
Open circuits are circuits that are opened, meaning that whenever you turn on the light and it's an open circuit, it won't work cause the two wires are not connected, meaning it's not D.
Parallel circuits are circuits that are in one straight line, just like parallel lines, meaning the answer would be A. (Look at the picture and don't get confused with the other question that's the same question and has the same answers, they both have different pictures, so look at the pictures they give you whenever they ask the question so your getting the right answer)
Hope this helped.
It must be a mixture, because the ingredients can be separated. You can precipitate sugar from water, there's no chemical reaction involved. I actually made lemonade pops once and the lemon juice and sugar comes out of solution as the water freezes.
Answer:
6.1 km
Explanation:
Given that a plane travels 4.0 km at an angle of 25◦ to the ground, then changes direction and travels 10 km at an angle of 16◦ to the ground. What is the magnitude of the plane's total displacement? Answer in units of km
The magnitude of the total displacement D can be calculated by using cosine formula
Ø = 25 - 16 = 9 degree
D^2 = 4^2 + 10^2 - 2 × 4 × 10 × cos 9
D^2 = 16 + 100 - 80cos9
D^2 = 116 - 79.02
D = sqrt( 36.98)
D = 6.1 m
Therefore, the magnitude of the plane's total displacement is 6.1 km
Answer:
Explanation:
When standing sound wave is produced in a medium , distance between anti-node and next node is equal to a quarter of a wave length. Node is point of silence where sound intensity is zero or minima.
wave length = velocity / frequency
= 340 / 85
= 4 m
We must move by a distance of 4/4 = 1 m away from wall
to find the first quiet spot.
Answer: 1141km
Explanation:
Given the following :
Distance due west = 915m
Distance due North = 681m
The magnitude of the Displacement =?
The information above produces a right angle triangle and the magnitude of the displacement can be calculated using Pythagoras rule :
The Magnitude of the woman's Displacement represents the hypotenuse of the triangle:
From Pythagoras :
Hypotenus = √(opposite)^2 + (adjacent)^2
Hypotenus = √(915)^2 + (681)^2
Hypotenuse = √1300986
Hypotenuse= 1140.6077
The magnitude of woman's displacement = 1140.6077 = 1141(to the nearest kilometer).
