Answer:

the secondary voltage is 60 V.

Explanation:

Given;

number of turns on the primary coil, Np = 100 turns

number of turns on the secondary coil, Ns = 300 turns

voltage supply in the primary coil, Vp = 20 V

let the secondary voltage = Vs

Apply the following transformer equation to determine the secondary voltage;

[tex]\frac{V_s}{V_p} =\frac{N_s}{N_p} \\\\V_s = \frac{V_p \times N_s}{N_p}\\\\V_s = \frac{20 \times 300}{100} \\\\V_s = 60 \ V[/tex]

Therefore, the secondary voltage is 60 V.

Answer:

Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids.

Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

Answer:

Given parameters

Potential difference (V) = 220 V

Power of lamp 1 (P1) = 100 W

Power of lamp 2 (P2) = 60 W

Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.

We know that

Power = Voltage x Current

P = V x I

I = P/V

Lamp 1:

I1 = P1/V

I1 = 100/220

I1 = 5/11 A

Lamp 2:

I2 = P2/V

I2 = 60/220

I2 = 3/11 A

Net current (I) = I1 + I2

I = 5/11 + 3/11

I = 8/11

I = 0.7273 A

Hence, current drawn from the line is 0.727 A

Answer:

12 (Magnesium- Mg)

Explanation:

Looking at the four numbers, we have:

Magnesium, Silicon, Sulfur, and Chlorine.

We can eliminate two of the answers immediately just by looking at the periodic table.

Sulfur and Chlorine are on the nonmetal side of the periodic table. So that's definitely not it. That leaves Magnesium and Silicon.

Silicon is a Metalloid. Magnesium is an Alkaline earth Metal.

Metaloids are elements that have a mix of both metal and nonmetal properties (luster, how it feels, etc.). Since it's a MIX and Magnesium is just straight METAL-

We can say Magnesium has the most metallic properties.

I don't get what the relation here is. Venus is the hottest planet in our solar system. And yes, it's hotter than mercury despite mercury being closer to the sun. And your question talks about the coldest temperature measured which is -235 degrees Celsius. That surely isn't measured on Venus. I'm only wondering what Venus has got to go with cold and what exactly your question is

Answer:

the regular daily rises and falls in sea level caused by the gravitational attraction of the Moon and Sun on Earth.

Explanation:

Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.

Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.

This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.

The various types of ocean tides based on the position of the Earth, Moon and the Sun are;

I. Neap tides.

II. Spring tides.

III. Low tide.

IV. High tide.

V. Brown tide.

VI. Rip tide.

VII. Red tide.

The speed of a wave equals to Wavelength and Frequency. The SI unit of speed of wave is m/s. Thus, option D is correct.

The speed of wave is distance travelled by the wave in given time. It is related to both wavelength and frequency. Wavelength is measured in meters and frequency in hertz.

From the givens:

Frequency(f) = 2 Hz.

Wavelength(λ) = 10m.

Amplitude = 3m ( Amplitude does not affect the speed of wave)

Speed (v) = λ × f

               = 10 × 2

              = 20 m/s.

Therefore, the speed of the wave is 20 m/s. Hence, Option D is correct.

Answer:-4.1858

Explanation: I hate Acellus

If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.

Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.

the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.

i.e. F ∝ q₁q₂

F ∝ 1/r²

F ∝ q₁q₂/r²

F = kq₁q₂/r²

where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹

In this problem,

Given,

q₁ = 6.33×10⁻⁶ C

F = 0.115N

r = 1.44m

q₂ = ?

putting this values in the equation,

0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²

q₂ = 4.23 μC.

fem = -0.126 V

Explanation:

Faraday's law is

          fem =  [tex]- \frac{d \phi}{dt}[/tex]

where the flow is

          Ф = B . A = B A cos θ

bold letters indicate vectors.

In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1

           fem = [tex]- A \ \frac{dB}{dt}[/tex]

in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations

           fem = [tex]- A \frac{\Delta B}{\Delta t}[/tex]

let's calculate

           fem = - 0.7 (0.9 -0) / 5

           fem = -0.126 V
