Dominik [7]3 years ago

1. The reason shy biogas burns with a flame is that biogas is a combustible gaseous fuel. Biogas is made up of a mixture of methane (CH4) and carbon dioxide (CO2), along with other trace gases. Biogas is commonly made from animal manure, sludge in wastewater and landfills that contain organic waste.

2. When iron is heated strongly, it becomes red and hot, but it does not burn with a flame. This is because in order for us to be able to burn iron we would have to be able to heat the surface of iron to its ignition temperature. However, when we heat iron, it does not reach its ignition temperature, and therefore does not burn.

1 - Biogas is composed of flammable gases such as methane. This means It can combust.

2 - Iron itself cannot catch fire due to it´s physical make-up. Metals in general tend to not catch fire.

gizmo_the_mogwai [7]

Answer:

longitudinal engineering strain = 624.16

true strain is 6.44

Explanation:

given data

diameter d1 = 0.5 mm

diameter d2 = 25 mm

to find out

longitudinal engineering and true strains

solution

we know both the volume is same

so

volume 1 = volume 2

A×L(1) = A×L(2)

( π/4 × d1² )×L(1) = ( π/4 × d2² )×L(2)

( π/4 × 0.5² )×L(1) = ( π/4 × 25² )×L(2)

0.1963 ×L(1) = 122.71 ×L(2)

L(1) / L(2) = 122.71 / 0.1963 = 625.16

and we know longitudinal engineering strain is

longitudinal engineering strain = L(1) / L(2)  - 1

longitudinal engineering strain = 625.16  - 1

longitudinal engineering strain = 624.16

and

true strain is

true strain = ln ( L(1) / L(2))

true strain = ln ( 625.16)

true strain is 6.44

The maximum speed at which a patch of the surface moves during a vibration is 4.5 m/s . What is the amplitude of the vibration,
frutty [35]

Answer:

a) Angular frequency, w = 0.0184 rad/s

b) Amplitude of vibration = 245 m

Explanation:

a) Angular frequency, w = 2πf

f = 1/T, T = 5.7 minutes = 5.7 × 60 = 342 s

f = 1/342 = 0.00292 Hz or 0.00292/s

w = 2π (0.00292) = 0.0184 rad/s

b) Amplitude of simple harmonic motion,

displacement of simple harmonic motion, x(t) = A cos (wt-Φ)

A = amplitude

v = dx/dt = - Aw (sin (wt - Φ)

Velocity amplitude of simple harmonic motion = Amplitude × angular frequency

Amplitude = (velocity amplitude)/(angular frequency) = 4.5/0.0184 = 245m

Hope this Helps!!!

Your electricity bill says 834-kWh of consumption. With this amount of energy, how many 59-W light bulbs can be powered for an a
kvv77 [185]

Answer:

2019 light bulbs

Explanation:

So the electrical energy consumed by each 59-W light bulb within 7 hours is the product of the power and time duration

E = Pt = 59 * 7 = 413 Wh or 0.413 kWh

If each light bulb consumes 0.413 kWh, then the total number of light bulbs needed to consume 834 kWh would be

834 / 0.413 = 2019 light bulbs
