Answer:
4 Ohms
Explanation:
The challenging part in this circuit is the bridged setup (diamond-shaped arrangement made of the 4 Ohm resistors). In general, this would first need to be transformed using the Wye-Delta transform to be solved, but in this case we can make a valid simplification: since the diamond arrangement is completely symmetrical, the voltage at the top and the bottom tip of the "diamond" will be identical and no current flows through the 4 Ohm bridge, hence, this resistor can be removed without changing the resulting resistance. After this, it is easy to see that the equivalent resistance of the modified "diamond" is just 4 Ohms.
The remaining top parallel branch of the circuit will be 8 Ohms, and the bottom parallel branch is nominally 8 Ohms. The resulting resistance therefore is 4 Ohms.
(The answer is not 2 Ohms!)
Light is a very complex phenomenon, but in many situations its behavior can be understood with a simple model based on rays and wave fronts. A ray is a thin beam of light that travels in a straight line. A wave front is the line (not necessarily straight) or surface connecting all the light that left a source at the same time. For a source like the Sun, rays radiate out in all directions; the wave fronts are spheres centered on the Sun. If the source is a long way away, the wave fronts can be treated as parallel lines.
Rays and wave fronts can generally be used to represent light when the light is interacting with objects that are much larger than the wavelength of light, which is about 500 nm. In particular, we'll use rays and wave fronts to analyze how light interacts with mirrors and lenses.
The volume in units of 6.03x10^3 in3
1ft = 12 inch
So to convert foot into inches we have to multiply by 12
The volume of container = 3.49ft^3
=3.49×12×12×12
= 6030.72 in^3
<h3>
What is the volume of a container?</h3>
The amount of space a container encloses, or how much room is inside of it, is measured by its volume. The volume of a box can be calculated using this straightforward formula: volume V = L × W × H for a box with height H, width W, and length L.
Many different units can be used, however because of the way this formula is written, the volume would have length to the third power dimensions. For instance, if the container's measurements are given in metres, the capacity of the box will be given in metres squared, or m3.

Answer:
No because it could run out of gas quicker or get into a reck.
Explanation:
Answer:
m = 0.0125 kg
Explanation:
Let us apply the formula for the speed of a wave on a string that is under tension:
where F = tension force
μ = mass per unit length
Mass per unit length is given as:
μ = m / l
where m = mass of the string
l = length of the string
This implies that:
Let us make mass, m, the subject of the formula:
From the question:
F = 20 N
l = 4.50 m
v = 85 m/s
Therefore:
