It's B.

The current passing through each bulb is the same. As you add more light bulbs, the current will decrease in each, but it will always be the same current passing through each one.

Answer:

The correct answer is option b) "The current passing through each bulb is the same."

Explanation:

A series circuit is one where there is only one path for the current, from the power supply source through all the elements of the circuit, to return again to the source.

Because the current flowing through it only has one way to go, the same amount of current will be supplied at the same intensity throughout the circuit.

The equivalent or total resistance of the circuit is the sum of the resistances that compose it and will be greater than the greater of the resistances of the circuit. This means that as we add terminals (the devices connected to the power grid, which receive the current and transform it into another type of energy), the resistance increases.

Taking into account the definitions and characteristics above, the correct answer is option b) "The current passing through each bulb is the same."

What is the electric force acting between two charges of -0.0050 C and 0.0050 C that are 0.025 m apart?

nika2105 [10]

Answer:

(A) $-3.6\times 10^8\ N$

Explanation:

Given:

Charge of one particle (q₁) = -0.0050 C

Charge of another particle (q₂) = 0.0050 C

Separation between them (d) = 0.025 m

We know that, from Coulomb's law, electric force acting between two charged particles is given as:

$F_e=\dfrac{kq_1q_2}{d^2}\\\\Where,k\to Coulomb's\ constant = 9\times 10^9\ N\cdot m^2/C^2$

Plug in the given values and solve for electric force, $F_e$ . This gives,

$F_e=\frac{(9\times 10^9\ N\cdot m^2/C^2) (-0.0050\ C)(0.0050\ C)}{(0.025\ m)^2}\\\\F_e=\frac{-2.25\times 10^{-4}\times 10^9}{6.25\times 10^{-4}}\ N\\\\F_e=-3.6\times 10^8\ N$

Therefore, option (A) is correct. Negative sign implies that the nature of electric force is attraction.

A 1 200-kg automobile moving at 25 m/s has the brakes applied with a deceleration of 8.0 m/s2. How far does the car travel befor

Alja [10]

Answer:

Δx = 39.1 m

Explanation:

Assuming that deceleration keeps constant during the braking process, we can use one of the kinematics equations, as follows:

$v_{f} ^{2} - v_{o} ^{2} = 2* a * \Delta x (1)$

where vf is the final velocity (0 in our case), v₀ is the initial velocity

(25 m/s), a is the acceleration (-8.0 m/s²), and Δx is the distance

traveled since the brakes are applied.

Solving (1) for Δx, we have:

$\Delta x = \frac{-v_{o} ^{2} }{2*a} = \frac{-(25m/s)^{2}}{2*(-8.0m/s2} = 39.1 m (2)$

The fundamental frequency of a standing wave on a 1.0-m-long string is 440 Hz. What would be the wave speed of a pulse moving al

Nana76 [90]

Answer: v = 880m/s

Explanation: The length of a string is related to the wavelength of sound passing through the string at the fundamental frequency is given as

L = λ/2 where L = length of string and λ = wavelength.

But L = 1m

1 = λ/2

λ = 2m.

But the frequency at fundamental is 440Hz and

V = fλ

Hence

v = 440 * 2

v = 880m/s

Accomplished silver workers in india can pound silver into incredibly thin sheets, as thin as 3.00 10-7 m (about one-hundredth o

postnew [5]

The density of silver is ρ = 10500 kg/m³ approximately.

Given:
m = 1.70 kg, the mass of silver
t = 3.0 x 10⁻⁷ m, the thickness of the sheet

Let A be the area.
Then, by definition,
m = (t*A)*ρ

Therefore
A = m/(t*ρ)
= (1.7 kg)/ [(3.0 x 10⁻⁷ m)*(10500 kg/m³)]
= 539.7 m²

Answer: 539.7 m²
