it takes about 26 seconds for speed of light with approximate speed of 3\times10^5  kilometers per second to reach Jupiter.

To calculate the time it takes light to reach Jupiter, we need to know the distance between the Sun and Jupiter. The average distance between the Sun and Jupiter is approximately 778 million kilometers. We can use the formula distance = speed x time to calculate the time it takes for sunlight to reach Jupiter. We know that the speed of light is approximately 3x10^5 kilometers per second and the distance between the Sun and Jupiter is 778 million kilometers.time = distance / speed

time = (77810^6 km) / (310^5 km/s)

time = 26 sec (approximately)

Therefore, it takes about 26 seconds for light to reach Jupiter.

With a net electric flux of -3. 63 1016 N/m2/C at its surface, the planet Mars has an electric field that is somewhat similar to that of the earth. There will be 3.26 x [tex]10^{5}[/tex]  of electric charge throughout the entire earth.

The electric flux across any closed surface is proportional to the net electric charge q enclosed by the surface, according to Gauss's law of electricity, which reads as = q/0, where 0 is the electric permittivity of free space, which has a value of 8.854 10-12 square coulombs per newton per square meter.

E is the magnitude of the electric field (with units of V/m), S is the area of the surface, and is the angle between the electric field lines and the normal (perpendicular) to S. If the electric field is uniform, the electric flux (E) travelling through a surface of vector area S is: E = ES = EScos.

Ф = q/ε

⇒ 3.69 x [tex]10^{16}[/tex] x = q/ 8.85 x [tex]10^{-12}[/tex]

Answer:

6 m/s

Explanation:

Velocity = Distance/Time

              = 84 meters/14 seconds

              = 6 m/s

Hope this helps! :)

We know, formula of capacitance in parallel plate capacitor is given by :

[tex]C = \dfrac{\epsilon_o A}{d}[/tex]

Here, [tex]\epsilon_o = 8.85 \times 10^{-12} \ F.m^{-1}[/tex]

So,

[tex]A = \dfrac{Cd}{\epsilon_o}\\\\A = \dfrac{1.11 \times 10^{-9}\times 8.89 \times 10^{-7}}{8.85\times 10^{-12}}\\\\A = 1.11 \times 10^{-4}\ m^2 \ or \ 1.11 \ cm^2[/tex]

Hence, this is the required solution.

Answer:

7.09797297 • 10^-7

Explanation:

You just follow the formula:

C = εA/d

ε = 8.85 • 10^-12

A = 8.89 • 10^-7

D = 1.11• 10 ^-9

So:

C = (8.85 • 10^-12)(8.89• 10^-4)/1.11 • 10 ^-9 = 7.09797297 • 10^-7

Static stretching and passive stretching are very similar in that they both involve moving the limbs into and holding the stretch posture.

Static stretching involves the individual holding their own limbs in place, while passive stretching involves a partner assisting with the movement and holding of limbs. When you stretch to your limit and hold that position, you are engaging in a form of stretching known as static stretching. Passive stretching, on the other hand, is also a form of static stretching; however, during this technique, you remain relaxed and do not actively participate in increasing your range of motion.

A radio message is sent home by astronauts in a spaceship approaching Mars at a distance of from Earth.

A contact from Mars travels [between 3 and 22] minutes at light speed to reach Earth. Relativity contributes to the fact that the distance between Earth and Mars is 1.26 seconds longer.

A Mars year is roughly equivalent to two Earth years because of Mars' nearly two-fold longer orbital period than the Earth's. Earth and Mars are 57.6 million kilometers (35.8 million miles) from one another, while 401 million kilometers separate them at their farthest point (249 million mi).

The sole means of contact between Earth and Mars are radio and messenger. A courier will undoubtedly require a lot of time. We can determine how long it will take a radio message to travel between the two planets since radio waves travel at the speed of light (299,792 km/s; 186,282 mi/s). When the two planets are at their closest, the one-way voyage takes the fewest amount of time—3.2 minutes.

The time required for a one-way trip is 22.3 minutes when they are the furthest apart. A round-trip message will take between 6.4 and 44.6 minutes to send and receive. Of course, receiving an answer will take the same amount of time in each situation.

The formula that shows the relationship between the surface area (S) and volume (V) for spheres is S = 4πr² and V = (4/3)πr³ where r is the radius of the sphere.

This formula shows that the surface area of a sphere is directly proportional to the radius squared, and the volume is directly proportional to the radius cubed. This means that as the radius of a sphere increases, the surface area and volume will increase at a much faster rate. For example, a sphere with a radius of 2 will have four times the surface area and eight times the volume of a sphere with a radius of 1.

Eudora spent 0.5 hours from home to library and 1.5 hours from library to school.

Given that,

Average speed from home to library S₁ = 12 km/h

Average speed from library to school S₂ = 76 km/h

Total distance = 120 km

Time = 2 hrs

Let the time spent from home to library  be x. So, from library to school will be = 2 - x

S₁ = 12 km/h

Time spent from home to library T₁ = x

S₂ = 76 km/h

Time spent from library to school T₂ = 2 - x

Distance can be calculated as, D₁ = S₁ T₁ = 12 x

D₂ = S₂ T₂ = 76(2 - x) = 152 - 76 x

As, D₁ + D₂ = 120

12 x + 152 - 76 x = 120

-64 x = -32

x = 0.5

So, T₁ = 0.5 hrs

In the given reaction, 2Mg(s) + O₂ (g) → 2MgO (s), 88.7 kJ of energy will be released.

The reaction 2Mg(s) + O₂ (g) → 2MgO (s) involves the release of energy from the system and hence it is an exothermic reaction. 21.2 kcals of energy is released from this reaction.

21.2 kcals = 21.2 × 10³ calories

1 cal = 4.184 J

For 21.2 × 10³ calories,

21.2 × 10³ cal × 4.184 = 88.70 × 10³ cal

To convert J to kJ, we divide it by 10³

88.70 × 10³ / 10³ = 88.70

Q is the charge's magnitude, V is its velocity, X is the angle formed by the magnetic field's direction and the charge's motion, and B is the strength of the magnetic field.

We must divide this amount by the mass of the charged particle or particles in order to determine the acceleration. Its speed at a later time is 1. 20 Mm/s (non relativistic because v is much less than the speed of light). When a refractive index diminishes over time, light shifts its frequency, which is referred to as photon acceleration [13,14].

It is to be noted that based on the information provided, it is not possible to calculate the distance of the planet from its sun as we need more information about orbit and its eccentricity.

The distance of your fictional planet from its sun, and its orbital period, can be calculated using the information you've provided about its day duration, orbit duration, year duration, and radius.

The distance between a planet and its sun is known as an astronomical unit (AU). To calculate the distance in AU, you can use the formula: d = (T² * G * M_sun) / (4 * pπ²)

where T is the planet's orbital period in Earth years, G is the gravitational constant (6.67 x 10^-⁻¹¹ m³ kg^⁻¹ s^⁻²), M_sun is the mass of the sun (2 x 10^30 kg), and pi is the mathematical constant (3.14).To find the orbital period you need to know year duration in seconds and divide it by 365.25 for Earth-based standard.

With that you can calculate the distance of the planet from its sun. The calculation of axial precession, tilt and oscillation etc don't provide information about the distance from its sun or the orbital period, It helps us to understand the planet's rotation around it's axial and the behaviors of the planet's climate because of axial tilt, precession and oscillation

Also, radius, planet mass and circumference also don't provide any information about distance of the planet from its sun or the orbital period as well.
