Answer:

the most elliptical orbit is that of COMETA

Explanation:

The eccentricity of a curve in defined as the ratio between lacia to the focus, called c and the value of the axis greater than

         ε = c / a

if we use Pythagoras' theorem

         c = \(\sqrt{a^2 - b^2}\)

   substituting

           ε = \(\sqrt{1 - (b/a)^2 }\)

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=\(\sqrt{1- x} \\ x = (\frac{b}{a} )^2\)

if we expand in series

             ε = 1 - x/2  

             ε=  \(1 - \frac{1}{2} \ (\frac{ b}{a} )^2\)

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = \(\sqrt{1- 0.98675^2}\)

               ε = 0.16

a very small ellipse

Planet X, despite not having data, it seems that the sun is in the scepter of the orbit, so b = a

therefore  both the semi-axes of the curve

        e = a / b

Consequently, the most elliptical orbit is that of COMETA.

Before moving away from the right curb to enter traffic, it is essential to perform several important checks to ensure a safe maneuver.

First, ensure that your vehicle is properly positioned close to the right curb, allowing enough space for traffic to pass on your left. Adjust your side and rearview mirrors to provide maximum visibility.

Once your vehicle is properly positioned, activate your turn signal to indicate your intention to merge into traffic. Check your rearview mirror to assess the speed and distance of approaching vehicles. Then, glance over your left shoulder to check your blind spot, an area that may not be visible in your mirrors.

This last shoulder check is critical as it helps you identify any vehicles, cyclists, or pedestrians that may be approaching from behind and could potentially be in your path as you move away from the curb. By performing this check, you can ensure that there are no hidden hazards and that it is safe to merge into the traffic lane.

Remember, maintaining awareness of your surroundings and performing the necessary checks before entering traffic is vital for a safe and successful merge.

Answer:

Explanation:

Answer:

The correct option is (d). "3x stronger".

Explanation:

The force between two charged particle is given by :

\(F=k\dfrac{q_1q_2}{r^2}\)

If one charge is tripled, \(q_1'=3q\)

New force will be :

\(F'=\dfrac{kq_1'q_2}{r^2}\\\\=3\times F\)

It means if one of the charges were to triple in strength, then the force will become 3 times of the initial force.

The magnitude and direction of the electric field at a point on the y-axis (y = a) due to charges 2q and -q located at the origin and x = 2a respectively can be determined using the principles of electrostatics.

To find the electric field at a point on the y-axis, we can consider the contributions from both charges. The electric field due to a point charge is given by Coulomb's Law, which states that the magnitude of the electric field (E) is proportional to the magnitude of the charge (q) and inversely proportional to the square of the distance (r) between the charge and the point of interest.

For the charge 2q at the origin, the electric field at a point on the y-axis can be calculated using the formula \(E1 = k(2q)/(r1^2)\), where k is the electrostatic constant and r1 is the distance between the charge 2q and the point on the y-axis.

Similarly, for the charge -q at x = 2a, the electric field at the same point can be calculated using the formula \(E2 = k(-q)/(r2^2)\), where r2 is the distance between the charge -q and the point on the y-axis.

To find the total electric field at the point, we need to consider the vector sum of the electric fields due to each charge. The direction of the electric field at the point on the y-axis will depend on the directions and magnitudes of the individual electric fields.

By calculating the magnitudes and directions of E1 and E2, we can determine the magnitude and direction of the total electric field at the point on the y-axis.

For this problem, lets use the kinetic energy formula

Where m is equal to mass and v is equal to velocity

In our given, we have:

velocity = 60 m/s

kinetic energy = 6,025,000 J

Plug these numbers into the formula to get the mass

m = 3347.222 kg

The magnitude of car's displacement is 17.78 m.

Given that, distance travelled due north is 11.8 m

Distance travelled due east is 13.3 m

As it is said that the car travels north and then east, it forms the two sides of a right-angled triangle. The magnitude of third side is the magnitude of car's displacement.

From Pythagoras theorem, the expression for car's displacement can be written as,

AC² = AB² + BC²

where, AB and BC are the sides of the right triangle

AC is the displacement of the car

Making AC as subject, we have,

AC = √(AB² + BC²) = √(11.8² + 13.3²) = √(139.24 + 176.89) = 17.78 m

Thus, the magnitude of car's displacement is 17.78 m.

Answer:

A resistor of 160 ohms should be used to replace the current resistor

Explanation:

Applying,

Ohm's Law

V = IR................... Equation 1

Where V = Voltage of the battery, I = current, R = Resistance

From the question,

Given: I = 0.2 A, R = 120 ohms.

Substitute these values into equation 1

V = 0.2×120

V = 24 V

IF a current of 0.15 A is required,

make R the subject of equation 1

R = V/I............... Equation 2

Given: V = 24 V, I = 0.15 A

Substitute these values into equation 2

R = 24/0.15

R = 160 ohms.

Hence a resistor of 160 ohms should be used to replace the current resistor

The value of R is 379 kΩ. Answer: R = 379 kΩ.

Given data: Capacitance C = 8.0 µF

Voltage V = 11.0 V Charge q

= CV = 8.0 × 10⁻⁶ F × 11 V

= 88 × 10⁻⁶ C Initial voltage V₀ = 0 V

Final voltage V = 4.00 V Time t = 3.00 s

Let resistance R be x kΩ.

The voltage across the capacitor is given by, V = V₀(1 - e⁻ᵗ/ᵣ)

Where, τ = RC is the time constant of the RC circuit.

Substituting the given values,4.00 V = 0(1 - e⁻³/τ)⇒ 1 - e⁻³/τ

= 0V / 4.00 V = 0 / V₀ - e⁻³/τ⇒ e⁻³/τ

= 4.00 V / 11.0 V⇒ e⁻³/τ = 0.3636

Taking natural logarithm on both sides,

ln e⁻³/τ = ln 0.3636⇒ -³/τ

= -1.0094...⇒ τ = 3.03 s Since τ

= RC = 3.03 s,8.0 × 10⁻⁶ F × x × 10³ Ω

Based on the given information, it appears that the question is referring to a sound wave created by a horizontal spring that oscillates between having rings far apart, then close together, and then far apart repeatedly. To determine the number of wavelengths present in the sound wave, we need to examine the pattern of the wave and identify the complete cycles.

A wavelength represents the distance between two consecutive points in a wave that are in phase, meaning they have the same amplitude and phase. In the given scenario, the wave pattern starts with rings far apart, then progresses to rings close together, and finally returns to rings far apart. This pattern completes one cycle of the wave.

Therefore, there is one complete wavelength present in the sound wave shown. The wave starts at a certain point, completes a cycle as it goes through the rings far apart, rings close together, and rings far apart again, and then repeats the same pattern for subsequent cycles.

Hence, the correct answer is 1 wavelength.
