Answer:

A. Recall Ohm's Law: V = IR

If V = 45 volts, and I = 5 amps, the R = V/I = 45V/5A = 9Ω

B. We know the potential difference and the resistance, both of which have good units. All we have to do is plug the known values into the equation and solve for the current:

I=15V9Ω

Thus, the electric current is: 1.67A

Archimedes' Principle

Explanation:

Its because Archimedes' Principle states "that the buoyant force on an object is equal to the weight of the fluid displaced by the object.... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object."

Answer:

The particles will more likely to move faster since they are converted from a liquid to gas.

Rules for States of Matter:

1. Solid particles always are packed close together and don't have much space to move.

2. Liquid particles have space to move around but are still packed together, but not as close as solid.

3. Gas particles are moving freely, in fact they are in the air! Gas particles are free to move wherever. For example, the air has gas particles that are constantly bumping into each other.

Let me know if I am right =)

Answer:

5 m/s

Explanation:

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.

Car's force is 12000 N.

Explanation:

→ Force = Mass × Acceleration

→ Force = 2000 kg × 6 m/s²

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:

B

Explanation:

the balloon has a negative charge and the metal sphere has a positive charge

Answer: B

Explanation:

The balloon will pick up stray electrons, so it will become negatively charged. Since it is attracted to the metal sphere, the sphere must be positively charged.

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.

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.
