We live in universe driven by dark energy consists stars and planets where every object have some mass and contains other properties too.
Dark energy has the cosmoslogists scratching their heads. Perceptions taken by NASA's Hubble Space Telescope and future space telescopes will be required to decide the properties of dull energy, which makes up around 70% of the universe.
Testing dark energy, the energy in void space making the growing universe speed up, calls for precisely estimating how that development rate is expanding with time. Dark energy is remembered to divide space.
Cosmologists accept around 70% of the universe comprises of dull energy, 25% is dim matter, and just four percent typical matter (the stuff that stars, planets and individuals are made of). Hubble perceptions recommend the dim energy might be Einstein's cosmological consistent, an energy permeating out of the vacuum of the space between universes.

which is a major difference between what we've seen in discovered exoplanets and our own solar system?
The major difference between what we've seen in discovered exoplanets and our own solar system is that extrasolar planet orbits tend to be closer and more eccentric than in our Solar System.
Exoplanet:
Any planet outside of our solar system is an exoplanet. The majority of exoplanets orbit other stars, while rogue planets—free-floating exoplanets that are unattached to any star—orbit the galactic center.
All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets.
Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit.

true or faule because only one path exists for the current to flow through a series circuit, it must flow through each resistor in the circuit.
In a series circuit, there is only one path for the current to go, hence each resistor in the circuit must conduct current. For series-connected resistors, this assertion is accurate.
Why does a series circuit just have one path for current?This is thus because a series circuit only has one path for current to move along. Since conductors carry electric charge, the rate of flow at any point in the circuit at any given instant must be equal.
What takes place when a circuit path is damaged?Current will stop flowing in the circuit if any section of this path is damaged. Any series-connected set of parts in a circuit that doesn't have any junctions must all have the same amount of current flowing through them.

The rope-and-pulley system of negligible mass shown above supports a block of weight w that is at rest. if the tension throughout the rope is uniform.
To determine the reading on the spring scale, we can apply Newton's Second Law of Motion to the block of weight w. The net force on the block is equal to the block's mass times its acceleration: F net = ma The only force acting on the block is the force of gravity, which is equal to the weight of the block: F net = F gravity = w The acceleration of the block is zero, since it is at rest: w = ma = m * 0 . This equation tells us that the force of gravity on the block is zero, which means that the block is in equilibrium and the tension in the rope is zero.

The diagram shows a spring scale attached to the ceiling. Below the spring, 2 pulleys are attached, holding the block at 2 separate points. As a result, there will be 4 ropes (2 attached to the spring scale, and 2 to the ceiling).
Because the tension is dispersed evenly among the 4 points, we can say that the scale will only read half the weight as the rest of the tension will be held by the ceiling.
Therefore, the spring scale will read W/2

d. The skydiver has the fastest speed at 3 seconds
The skydiver has the fastest speed at 4 seconds, and the correct statement is (b) "The skydiver has the fastest speed at 4 seconds".
To determine the skydiver's speed at each second, we need to consider the forces acting on the skydiver. In this case, the forces acting on the skydiver are the weight of the skydiver and the air resistance. The weight of the skydiver is constant at 500 N, while the air resistance increases with time.
According to Newton's second law of motion, the acceleration of an object is equal to the net force acting on it divided by its mass. In this case, the mass of the skydiver is not given, so we cannot calculate the acceleration directly.
Speed is the rate of change of displacement over time. In this case, the displacement of the skydiver is not given, so we cannot calculate the speed directly. However, we can use the information provided to determine the skydiver's speed at each second.
From the table, we can see that the air resistance increases with time, reaching a maximum of 500 N at 4 seconds. This means that the net force acting on the skydiver is greatest at 4 seconds, which would correspond to the highest acceleration and the fastest speed.

why the force needed to keep an object traveling in the same size circle is larger the faster the object is going.
A body's direction constantly shifts as it circles around. This shift in direction causes a change in velocity, which causes the motion to accelerate. We know from Newton's First Law that an external force is necessary to produce acceleration. Therefore, a force is required to maintain the body's circular motion.
What force must be applied to maintain an object's motion in a circle?A net force called a centripetal force acts on an object to keep it moving in a circular motion.
According to Newton's first law, unless a force acts on an object, it will either stay in place or continue to move at a constant speed. Inertia is the term for this notion. An object has more inertia the heavier it is (or the more mass it has). Due to their greater inertia, heavy objects are more difficult to move than light ones.

a uniform thin rod of length 0.50 m and mass 4.0 kg can rotate in a horizontal plane about its center. a 3.0 gram bullet hits the end of the rod (initially at rest) at an angle of 60 degrees and imbeds in the rod. if the angular speed of the rod is 10. rad/s after the bullet strikes, what is the speed of the bullet before it strikes the rod?
The speed of the bullet before it strikes the rod is 67 m/s. To determine the speed of the bullet before it strikes the rod, we need to consider the conservation of angular momentum.
The moment of inertia of a thin rod about its center is given by the following formula:
I = (1/3) * m * L^2where I is the moment of inertia, m is the mass of the rod, and L is the length of the rod.
Substituting the values given in the problem, we find that the moment of inertia of the rod is
(1/3) * 4.0 kg * (0.50 m)^2 = 0.67 kg*m^2.In this case, the bullet strikes the rod, transferring some of its linear momentum to the rod in the form of angular momentum. The change in angular momentum of the rod is equal to the angular momentum of the bullet.
We can use the conservation of angular momentum to write the following equation:
I1 * w1 + J = I2 * w2where I1 is the initial moment of inertia of the rod, w1 is the initial angular velocity of the rod, J is the angular momentum of the bullet, I2 is the final moment of inertia of the rod, and w2 is the final angular velocity of the rod.
Since the initial angular velocity of the rod is zero, we can simplify the equation as follows:
J = I2 * w2
Substituting the values given in the problem, we find that the angular momentum of the bullet is
0.67 kgm^2 * 10 rad/s = 6.7 kgm^2/s.To determine the speed of the bullet before it strikes the rod, we need to consider the bullet's mass and the angle at which it strikes the rod. The mass of the bullet is given as 3.0 grams, which is equivalent to 0.003 kg. The angle at which the bullet strikes the rod is given as 60 degrees.
We can use the following formula to calculate the speed of the bullet before it strikes the rod:
v = (J/m) * sin(theta)Substituting the values given in the problem, we find that the speed of the bullet before it strikes the rod is (6.7 kg*m^2/s / 0.003 kg) * sin(60 degrees) = 67 m/s. This is the final answer.

describe how energy travels from the nuclear core of the sun to the atmosphere. in your answer, include the name of each layer and describe how energy moves through the layer.
Energy travels from the nuclear core of the Sun to the atmosphere through a process called thermal radiation. Thermal radiation is the emission of electromagnetic waves from a body due to its temperature.
The Sun is composed of several layers, including the core, the radiative zone, and the convective zone. Energy travels through these layers as follows:
1. Core: The core is the innermost layer of the Sun and is where nuclear fusion reactions take place. In these reactions, hydrogen atoms are combined to form helium, releasing a large amount of energy in the process. This energy is in the form of electromagnetic radiation, including visible light and ultraviolet radiation.
2. Radiative zone: The radiative zone is the layer of the Sun just outside the core. In this layer, the energy released in the core is transported outward through the process of thermal radiation. Photons, or particles of light, are emitted from the surface of the core and travel through the radiative zone, gradually losing energy as they move outward.
3. Convective zone: The convective zone is the outer layer of the Sun. In this layer, the energy transported by thermal radiation is not enough to sustain the temperature of the Sun, so the energy is transferred through the process of convection. In convection, hot gas rises and cool gas sinks, resulting in the transfer of heat from the interior of the Sun to the surface.
Overall, energy travels from the nuclear core of the Sun to the atmosphere through the process of thermal radiation and convection. These processes help to transport energy from the core of the Sun to the surface, where it is emitted into space as electromagnetic radiation.

which type of wave has a wave perpendicular to the disturbance?responses surface surface longitudinal longitudinal mechanical mechanical transverse
The disruption of a transverse wave propagates perpendicular to the direction of propagation.
Depending on the type of motion they experience, mechanical waves can either be transverse or longitudinal. It should be emphasized that transverse and longitudinal waves can both have periodic behavior.
Transverse wave: what is it?
An oscillating wave that moves in the opposite direction of its oscillations is referred to as a transverse wave in physics. On the other hand, a longitudinal wave travels in the direction of its oscillations. Water waves are transverse waves.
A transverse wave is what sort of wave?
Transverse waves include phenomena like string vibrations and sea surface ripples. The slinky may be swung horizontally up and down to produce a transverse wave. A longitudinal wave's particles are scattered perpendicular to the direction that the wave is moving.

questions 10-11 refer to a ball that is tossed straight up from the surface of a small, spherical asteroid with no atmosphere. the ball rises to a height equal to the asteroid's radius and then falls straight down toward the surface of the asteroid. 10. what forces, if any, act on the ball while it is on the way up?
Only a decreasing gravitational force that acts downward will apply on the ball that is tossed straight up from the surface of a small, spherical asteroid with no atmosphere.
What is gravitational force?All physical things with mass are drawn to the gravitational force, which can be thought of as an attracting force. It is the known natural force that is by far the weakest.The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward each other by gravity.
Hence,
