Planet A exerts a force on planet B, the magnitude and direction of the gravitational force planet B exerts on planet A the gravitational force exerted by planet B on planet A is the same as the magnitude of the gravitational force exerted by planet A on planet B

Newton's third law states that if object A exerts a force on object B, then object B exerts an equal and opposite force on object A. Hence, if planet A exerts a gravitational force on planet B, then planet B exerts an equal and opposite gravitational force on planet A.The magnitude of the gravitational force exerted by planet B on planet A is the same as the magnitude of the gravitational force exerted by planet A on planet B, this is according to the law of universal gravitation,

This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The direction of the gravitational force exerted by planet B on planet A is towards planet B's center, just as the direction of the gravitational force exerted by planet A on planet B is towards planet A's center. Therefore, we can say that the magnitude and direction of the gravitational force planet B exerts on planet A is equal and opposite to the gravitational force planet A exerts on planet B

The discovery that electrons move around the nucleus billions of times in one second can be attributed to multiple scientists. However, the most notable contribution came from Niels Bohr.

In 1913, Bohr proposed his atomic model, which introduced the concept of quantized energy levels for electrons. According to this model, electrons orbit the nucleus in specific, well-defined energy levels or shells.

These energy levels are characterized by their respective energy values, and electrons can transition between them by either absorbing or emitting energy. Bohr's model successfully explained phenomena like atomic spectra, and his work laid the foundation for our current understanding of atomic structure.

Overall, Bohr's model revealed the dynamic nature of electrons in their orbits and their rapid motion around the nucleus.

Answer:

21 m

Explanation:

Since the displacement from the door is 2 m West, we have our vector as -2i. The vector representing 14.0 m South is -14.0j. The vector representing 25.0 m East is 25.0i. The vector representing 11.0 m North is 11.0j. And, the vector representing 2.0 m West is -2.0i.

So, to get our position vector at the other location, we add all the vectors together.

So, r = -2i + (-14.0j) + 25.0i + 11.0j - 2i

= -4i + 25.0i - 14.0j + 11.0j

= 21.0i -3j m

Now, if we assume the position vector for the door is at the origin, we have r₀ = 0i + 0j m

So, our displacement from the door is r - r₀ = 21.0i - 3.0j - (0i + 0j) =  21.0i - 3.0j

So, the magnitude of the resultant displacement |r - r₀| = √(21.0² + 3.0²)

= 3.0√(7.0² + 1)

= 3.0√(49 + 1)

= 3.0√50

The additional charge that flows to the positive plate from the 8 Volts battery is  12 x 10⁻³ Coulomb's.

We have an uncharged capacitor which is charged in two different ways using battery of two different voltages. Firstly, it is connected to the terminals of a 4.0 V battery, and 12 μc of charge flows to the positive plate. Then, the 4.0 V battery is disconnected and replaced with a 8.0 V battery

We have to determine the Additional charge that flows to the Positive plate from this 8 V battery.

Capacitance is the ability of an object to collect and store energy in the form of an electrical charge. Mathematically -

C = Q/V

According to the question, we have -

Electric potential of battery 1 = V[1] = 4 V

Charge flow from battery 1 to the positive plate = Q[1] = 12 x 10⁻³ C

Electric potential of battery 2 = V[2] = 8 V

Now, using the following relation, we will find Q[2] {Charge flow from battery 2 to the positive plate} →

V[1] / V[2] = Q[1] / Q[2]

Substituting the values -

Q[2] = (12 x 10⁻³ x 8)/4 = 24 x 10⁻³ C

Additional Charge that flowed to the positive plate →

Q[2] - Q[1] = 12 x 10⁻³ Coulomb's

Hence, the additional charge that flows to the positive plate is  \(12\times 10^{-3}\) Coulomb's.

The magnitude of the coulombic force of attraction between a central charge of \(-2 * 10^-^5 C\) and the surrounding numbered charges can be determined by analyzing the electric field.

To determine the magnitude of the coulombic force of attraction, we need to analyze the electric field created by the central charge and its interaction with the surrounding numbered charges. The electric field is a vector quantity that describes the influence a charge exerts on other charges in its vicinity.

The magnitude of the coulombic force of attraction can be determined using Coulomb's law, which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.

First, calculate the electric field at the position of each numbered charge. The electric field at a given point is the force experienced by a positive test charge placed at that point. Once the electric field at each numbered charge is determined, multiply the magnitude of the electric field by the charge of the central charge and the charge of the numbered charge. This will give the magnitude of the force between the central charge and the numbered charge.

By following these steps for each numbered charge and summing up the forces, you can determine the magnitude of the coulombic force of attraction between the central charge and the surrounding numbered charges. Remember to consider the signs of the charges (+ or -) when calculating the force, as opposite charges attract each other while like charges repel.

for the man to return to the ship he must throw the balls in the opposite direction of the ship

Explanation:

For this exercise we can use the conservation of momentum. Let's form a system made up of man and baseballs.

Initial instant. Before throwing the balls

     p₀ = 0

Final moment. After throwing the balls

     \(p_{f}\) = M v + n m v '

where M is the mass of the man, m is the mass of each ball and n is the number of balls , v isthe speed man and v' is the speed ball

Since the forces are internal, the momentum of the system is conserved

     p₀ = p_{f}

      0 = M v + n m v ’

      \(v =- \frac{n \ m}{M} \ v'\)

If we analyze this expression, for the man to return to the ship he must throw the balls in the opposite direction of the ship

Answer:

An estimate for the time it will take for a spacecraft to travel from Earth to Mars is approximately 138.8 days

Explanation:

The distance between Earth and the Moon = 684,400 km

The distance between Earth and Mars = 220.58 × 10⁶ km

The distance between Earth and Pluto = 5.2241 × 10⁹ km

The ratio of the distance between Earth and Pluto and the distance between Earth and Mars = (5.2241 × 10⁹ km)/(220.58 × 10⁶ km) ≈ 23.683

It took 2006 to 2015 (9 years) to travel from Earth to Pluto, therefore, it can take approximately (9 years)/(23.683) ≈ 0.38 of a year which is ((9 years)/(23.683)) × 365.2422 ≈ 138.8 days for a spacecraft to travel from Earth to Mars

Answer:

42.5mph

Explanation:

The computation of the average speed is shown below:

As we know that

Speed = Distance ÷ Time

ANd, distance = Speed × time

So, the distance would be

= (50 × 5 hours) + (30 × 3)

= 250 + 90

= 340 miles

And, the total time taken is 8 hours

So, the average speed is

= 340 miles ÷ 8 hours

= 42.5mph

Explanation:

Given that a football coach walks 24 meters eastward, then 12 meters westward, then 36 meters eastward, and finally 22 meters westward. What is the magnitude and direction of the displacement?

Let eastward be positive and westward be negative.

Magnitude = 24 - 12 + 36 - 22

Magnitude = 60 - 34

Magnitude = 26

Since the answer is positive, the direction will be eastward.

Therefore,

Magnitude = 26 m
