A transformer has 100 turns on primary coil and 300 turn on secondary coil. If 20V Ac is applied to the primary coil, what would be the secondary voltage?
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.

A car with a mass of 2000 kg accelerates at 6 m/s'at a green light. What is the car's force?
Answer:
Car's force is 12000 N.
Explanation:
→ Force = Mass × Acceleration
→ Force = 2000 kg × 6 m/s²
→ Force = 12000 NA +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?
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.
What is coulomb's law ?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.

Which of ONE of the following four elements has the most metallic properties?
The atomic numbers of the elements are listed below.
12
14
16
17
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.

The speed of a wave with a frequency of 2 Hz (2/s), an amplitude of 3 m, and a wavelength of 10 m is
options:
0.2 m/s.
12 m/s.
5 m/s.
20 m/s.
Answer:
5 m/s
Explanation:
your welcome
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.
What is speed of wave?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.

2. A loop of wire of area 0.7 m is moving into a 0.9 T magnetic field. If it takes 5
seconds for the loop to move from completely outside the field to completely inside the
field, what emf is produced?
Answer:
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

6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.
