can someone explain why is the answer 3.1?​

If two identical airplanes are loaded such that one has the CG at the forward limit, and the other then the correct answer is: CG will not affect speed.

The position of the center of gravity (CG) affects the stability and control of an airplane, but it does not directly affect its speed. The speed of an airplane is determined by factors such as engine power, aerodynamic design, and external conditions (e.g., wind). The position of the CG primarily influences the longitudinal stability of the aircraft and its tendency to pitch up or down.

Therefore, the speed of the airplanes, in this case, would not be affected by the position of the CG. The airplane with the CG at the forward or aft limit may have different stability characteristics, but their speeds would not be inherently different due to CG placement alone.

The true statements are:Jupiter's Great Red Spot is in the southern hemisphere.The fastest wind speed recorded in our solar system is on Neptune.

Among the given statements, only two are true. Jupiter's Great Red Spot, a massive storm, is indeed located in the southern hemisphere of the planet. The Great Red Spot is a prominent feature on Jupiter, visible as a giant swirling storm system. On the other hand, the fastest wind speed recorded in our solar system, reaching speeds of up to 2,100 kilometers per hour (1,300 miles per hour), is found on Neptune.

The strong winds on Neptune contribute to its dynamic atmosphere and the formation of features like the Great Dark Spot. The remaining statements about Pluto, Saturn's moon Enceladus, and Uranus are not true according to our current understanding.

-KARL IS STOOPID

Explanation:

The maximum displacement of the block from its equilibrium position is 0.063 meters.

To solve this problem, we can first find the initial potential energy stored in the spring by using the formula: PE = 0.5kx^2, where k is the spring constant and x is the initial displacement from equilibrium (which is zero). Thus, the initial potential energy is 0 J. Then, we can use the principle of conservation of energy to find the maximum displacement of the block from its equilibrium position. Since there is no external work done on the block-spring system, the initial kinetic energy of the block is converted entirely into potential energy stored in the spring when the block reaches its maximum displacement. Using the formula for kinetic energy, KE = 0.5mv^2, where m is the mass of the block and v is the initial velocity, we can find the initial kinetic energy to be 1.44 J. Setting the initial kinetic energy equal to the final potential energy, we can solve for x to find the maximum displacement of the block from its equilibrium position to be 0.063 meters.

It is important to note that the almost instantaneous hit with the hammer means that we can assume the time interval over which the force is applied to be very short and thus the impulse of the force can be treated as an instantaneous change in momentum of the block. Therefore, the conservation of momentum principle can be ignored in the problem.

The mallet in contact with the ball is 2.4 milliseconds.

The amount of time that the mallet was in contact with the ball can be calculated using the equation for impulse, which is equal to the change in momentum. Force and time combine to create an impulse.. Mathematically, it can be expressed as:

Impulse = Change in Momentum = F * t

Change in momentum is the product of mass and change in velocity.Therefore, the time that the mallet was in contact with the ball can be calculated as follows:

\(t = \frac{Impulse }{F }\\ \\= \frac{(0.45 kg * 1.3 m/s) }{ 83 N }\\\\= 2.4 milliseconds\)

Therefore,The mallet in contact with the ball is 2.4 milliseconds.

Mathematically, the formula for the weight of Tarzan is given as;

W = mg

where;

The given parameters include;

the mass of Tarzan = 75 kg

acceleration due to gravity = 9.8 m/s²

W = 75 x 9.8

W = 735 N

The tension on the vine is calculated as follows;

Explanation:

Due to the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn together by a stronger gravitational attraction. As a result, the gravitational pull between two objects grows as their respective masses rise.

Since the gravitational force is exactly proportional to the mass of both interacting objects, heavier items will be attracted by stronger gravitational forces. Therefore, the gravitational attraction between two objects grows as their respective masses do as well.

The attraction created by gravity is between masses. The gravitational force, commonly known as the gravity force, increases with the size of the masses. With an increase in the distance between masses, the gravitational pull rapidly lessens.

Therefore, second have greater gravitational force.

According to Coulomb's law:

F₁ = k·q₁·q₂ / r₁²

F₂ = k·q₁·q₂ / r₂²

F₂ / F₁  = (r₁ / r₂)²

F₂ / F₁  = ( r₁ / (3·r₁)² = (1 / 3)² = 1 / 9

Answer:

A table of motion (for a moving object) usually is something like:

Time I Position:

0s           1m

1s            3m

2s           5m

etc...

Where time is the independent variable and position represents the position of the object at that given time.

We can think in these points as coordinate pairs, for example, we can wrote these 3 pairs as:

(0s, 1m)

(1s, 3m)

(2s, 5m)

Now that we have these points, we can go to a coordinate plane and find these points

(The time would be on the horizontal axis, and position in the vertical axis)

Once you found the points, to complete the graph you need to find a line that connects the points.

An example of this is shown below, where the points used are the ones above, and the line should be straight.

Explanation:

The light-gathering power of a 10 m Keck telescope is much greater than that of a 0.5 m telescope.

The light-gathering power of a telescope is determined by the size of its objective lens or mirror. A larger telescope with a larger objective collects more light, which allows for better resolution and the ability to observe fainter objects. Therefore, the light-gathering power of a 10 m Keck telescope is much greater than that of a 0.5 m telescope.

The Keck Observatory consists of two 10 m telescopes, each with a primary mirror composed of 36 hexagonal segments, that are used to observe the cosmos. The telescopes are located on the summit of Mauna Kea in Hawaii, and they can observe objects up to 13 billion light-years away. These telescopes are among the largest and most advanced in the world, allowing for unparalleled observations of the universe.

A 0.5 m telescope, on the other hand, has a much smaller objective and is typically used for amateur astronomy or as a backup telescope for larger observatories. While it can still be used to observe celestial objects, its light-gathering power is much less than that of a 10 m Keck telescope. This means that it will have a lower resolution and be less able to detect faint objects in the night sky.

In summary, a 10 m Keck telescope has a much greater light-gathering power than a 0.5 m telescope due to its larger objective lens. This allows for better resolution and the ability to observe fainter objects, making it one of the most advanced telescopes in the world.

The question is asking whether it is possible to find a magnetic vector potential for a given uniform surface current flowing in the xy plane and generating a magnetic field for different regions of space.

To determine whether it is possible to find a magnetic vector potential for the given scenario, we need to consider the conditions that must be satisfied. In general, a magnetic vector potential A can be found if the magnetic field B satisfies the condition ∇ × A = B. This is known as the magnetic vector potential equation.

In the given situation, the magnetic field is different for the regions above and below the xy plane. For z > 0, the magnetic field is described as B = MoK -î, and for z < 0, it is described as B = -MoK -î. To find the magnetic vector potential, we need to determine if there exists a vector potential A that satisfies the equation ∇ × A = B in each region.

By calculating the curl of A, we can check if it matches the given magnetic field expressions. If the curl of A matches the magnetic field expressions for both regions, then it is possible to find a magnetic vector potential for the given scenario. However, if the curl of A does not match the magnetic field expressions, then it is not possible to find a magnetic vector potential that satisfies the conditions.
