We have that these are some <em>reasons</em> why the light bulb isn't lighting up in a circuit

The Power Requirements to light .Not energy change can light up a bulb.
As well as poor connection ,the connections might be out at a <em>node </em>thereby removing power from the source.

<h3>Electricity </h3>

Generally, there are a series of reason why light bulbs may not light up i n a circuit system.

The power requirements to light up the bulb; not energy change can light up a bulb.

As well as poor connection ,the connections might be out at a <em>node </em>thereby removing power from the source.

How does an increase in temperature affect the volume of a liquid or gas

Ludmilka [50]

When the temperature increases the volume will increase, and when it cools it will decrease. This is because the molecules spread further apart as the temp gets higher, which creates a bigger volume.

You need to design a 60.0-Hz ac generator that has a maximum emf of 5200 V. The generator is to contain a 180-turn coil that has

OlgaM077 [116]

Answer:

0.082 T

Explanation:

Given:

Frequency of the generator (f) = 60.0 Hz

Maximum emf of the generator (E) = 5200 V

Number of turns (N) = 180

Area per turn (A) = 0.94 m²

Magnetic field magnitude (B) = ?

We know that, the angular frequency of the generator is given as:

$\omega=2\pi f$

Plug in the value of 'f' and solve for 'ω'. This gives,

$\omega=2\pi\times 60.0=120\pi\ rad/s$

Now, the maximum emf of the generator is given by the formula:

$E=NAB\omega$

Rewriting in terms of magnetic field, 'B', we get:

$B=\frac{E}{NA \omega}$

Plug in the given values and solve for 'B'. This gives,

$B=\frac{5200\ V}{180\times 0.94\ m^2\times 120\pi\ rad/s}\\\\B=\frac{5200\ V}{63786.897}\\\\B=0.082\ T$

Therefore, the magnitude of the magnetic field in which the coil rotates is 0.082 T.

The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 9.1 kN. Determine the requ

Oksana_A [137]

Answer:

T_ac = 6.586 KN

R = 10.51 KN

Explanation:

Given:

- Tension in cable T_ab = 9.1 KN

Find:

- Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A

- Determine the magnitude R of this downward force.

Solution:

- Compute the three angles as shown in figure attached, a, B , y:

a = arctan (40/50) = 38.36 degrees

B = arctan (50/30) = 59.04 degrees

y = 180 - 38.36 = 82.6 degrees

- Use cosine rule to calculate R and F_ac as follows:

sin(a) / T_ac = sin(B) / T_ab = sin(y) / R

sin(38.36) / T_ac = sin(59.04) / 9.1 = sin(82.06) / R

T_ac = 9.1 * ( sin(38.36) / sin(59.04) )

T_ac = 6.586 KN

R = 9.1 * ( sin(82.06) / sin(59.04) )

R = 10.51 KN

What was Einstein's hypothesis that provided evidence for the particle nature of light called?

Nookie1986 [14]

In 1905, Albert Einstein provided an explanation of the photoelectric effect, an experiment that the wave theory of light failed to explain. He did so by postulating the existence of photons, quanta of light energy with particulate qualities.
