What is the voltage output (in V) of a transformer used for rechargeable flashlight batteries, if its primary has 475 turns, its
VMariaS [17]

Answer:

Output voltage is 1.92 volts.

Explanation:

Given that,

Number of turns in primary coil, N_p=475

Number of turns in secondary coil, N_s=8

Input voltage, V_i=114\ V

We need to find the voltage output of a transformer used for rechargeable flashlight batteries. For a transformer, the number of turns and the voltage ratio is given by :

\dfrac{N_p}{N_s}=\dfrac{V_i}{V_o}\\\\\\V_o=114\cdot\dfrac{8}{475}\\\\V_o=1.92\ V

So, the output voltage is 1.92 volts.

A rms voltage of 120v produces a maximum current of 2.1a in a certain resistor. Find the resistance of the resistor. What is the
amid [387]

the resistance is 80.8Ω and average power 178.2 W

a) the value of resistance is given as,

R=rms voltage / rms current

and rms current = 2.1/√2

= I°/√2

rms current = 2.1/√2

rms current = 1.48

therefore R = 120/1.48

=80.4Ω

b) average power is product of rms current and rms voltage

P=120× 1.48

=178.2 W

HELP ASAP
hichkok12 [17]

Answer: I’m pretty sure it’s genetic information.

Explanation: Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.

How do electric insulators and conductors differ?
mixas84 [53]

Answer:

The most common difference between the two is that while conductors allow free flow of electrons from one atom to another, insulators restrict free flow of electrons. Conductors allow electrical energy to pass through them, whereas insulators do not allow electrical energy to pass through them.

A truck moving at 6.0 m/s applies the brakes and stops after skidding 12.0 m.
Vitek1552 [10]

Answer:

a) a= -1.5 m/s²

b) t = 4.0 s

Explanation:

a)

  • Since we are told that the deceleration is uniform, we can use the following kinematic equation:

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

  • Since the truck finally stops, this means that vf = 0.
  • Replacing the values of v₀, and Δx in (1), we can solve for a, as follows:

       a =\frac{-(v_{o}^{2})}{2*\Delta X} = \frac{-(6.0m/s)^{2} }{2* 12.0m} = -1.5 m/s2  (2)

b)

  • Since we know the value of the initial and final velocity, and the value of the acceleration also, we can apply the definition of acceleration, solving for time t, as follows:

       \Delta t = \frac{-v_{o}}{a} = \frac{-6.0m/s}{-1.5m/s2} = 4.0 s  (2)
