Answer: 20kg

Explanation: the above question is base on workdone...

Note: work done is also equal to potential energy.

➡Mathematical expression for the above statement:

W = P.E. where w and p.e are noted to be work done and potential energy...

Therefore; P.E = mgh

Where m is the mass of the object, g is the acceleration due to gravity and finally h is the height...

Therefore; P.E = mgh

600 = m x 10 x 3

600 = 30m

Divide both side by the coefficient of m

Therefore; 600/30 = m

m = 20kg

Answer:

mass = 20.408 kg

Explanation:

Formula:   GPE = mgh

Solve:

600 = m*9.8*3

600 = m*29.4

m= 600/29.4

m= 20.408 kg

Result:

20.408 kg

Answer:

which two statements describe how soil horizons are formed?

Explanation:

A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture.

Answer:

Explanation:

As soils develop over time, layers (or horizons) form a soil profile. Most soil profiles cover the earth as 2 main layers— topsoil and subsoil. Soil horizons are the layers in the soil as you move down the soil profile. A soil profile may have soil horizons that are easy or difficult to distinguish.

To accurately record the location of a star, you would typically need to measure the altitude, azimuth, and time.

Altitude: The altitude refers to the angle above the horizon at which the star is located. It is measured vertically from the observer's position.

Azimuth: The azimuth refers to the horizontal angle or direction in which the star is located. It is measured clockwise from a reference direction, often north.

Time: Recording the time of observation is crucial for celestial navigation and astronomy. It helps determine the position of the star relative to Earth's rotation and allows for calculations related to the star's apparent motion.

Therefore, to precisely record the location of a star, you would need to measure the altitude, azimuth, and time.

Explanation:

When the compass needle as you move the compass around, Then the compass needle follows the pattern of magnetic field lines. The correct option is C.

Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field around a magnet or a current-carrying wire. The pattern of magnetic field lines depends on the shape and orientation of the magnet or the wire, as well as the direction and strength of the magnetic field.

The magnetic field lines around a magnet emerge from the north pole and loop back into the south pole in a continuous path. They are always closed loops, meaning they do not begin or end anywhere but instead form a continuous path around the magnet. The magnetic field lines are closer together near the poles of the magnet, indicating a stronger magnetic field in those regions. They become less dense as they move further away from the poles, indicating a weaker magnetic field in those regions.

Here in the question,

When a compass is moved around, the compass needle aligns itself with the direction of the magnetic field lines in the vicinity. Magnetic field lines are the paths that a small compass would follow if it were placed at various points around a magnet. They indicate the direction of the magnetic field at each point.

The compass needle has a north-seeking pole and a south-seeking pole. The north-seeking pole of the compass needle aligns itself with the direction of the magnetic field lines, which are oriented from the north pole of a magnet to the south pole. This means that the north-seeking pole of the compass needle will point towards the south pole of a magnet, while the south-seeking pole of the compass needle will point towards the north pole of the magnet.

Therefore, as the compass is moved around a magnet or any other magnetic field, the compass needle will follow the pattern of the magnetic field lines, and the north-seeking pole of the compass needle will always point towards the south pole of the magnet or the magnetic field source.

Answer:

Net Force = 390 N

Explanation:

Net Force =  is the sum of all forces acting on an object.

450 N - 60 N = 390 N

The net force acting on the buggy is 390 N pointing to the right.

In physics, force is defined as: the push or pull on a mass that causes it to change velocity.

A force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction. The direction of the force is the point where force is applied, and the application of force is the point where force is applied.

A spring balance can be used to calculate force. Newton is the SI unit of force.

A short blue arrow over the cart is labeled [tex]F_f[/tex] = 60 N

And A long blue arrow over the horse is labeled [tex]F_P[/tex]= 450 N.

Hence, The net force acting on the buggy is = 450 N - 60 N = 390 N  pointing to the right.

Explanation:

The  ideas about the universe have been proven false are:

Universe is the totality of the matter and energy that makes up the cosmos, and of which Earth, and by extension, the human race, is a part. Since societies conceived of Earth, the Sun, and the Moon as the primary elements of creation and the rest of the universe as virtually an afterthought, humanity has come a long way.

Today, it is understood that Earth is but a tiny ball of rock in an unfathomably enormous universe, and that the formation of the solar system was most likely only one of numerous occurrences set against the background of a developed universe.

Answer:

the force of the football player would cause you to fall over and possibly get a concussion because the football players mass is probably more than yours and the velocity of the football player would cause you to fall over or in football terms "get tackled"

Explanation:

Explanation:

Newton stated within his first law of motion that any object of mass at rest (velocity, designated as v, is zero) will tend to stay at rest, and any object in motion (velocity is not zero) will tend to stay in motion at the same speed and direction (acceleration, designated as a, is zero), unless acted upon by a force.  Applied to football collisions, the more massive a football player (the more he weighs), the less likely he is to be slowed down, sped up, or diverted by an outside force, such as opponents. The first law is often called the law of inertia because the term inertia means the resistance to motion. For instance, the quarterback who desires to score a touchdown when very near to the goal line will often use the quarterback-sneak. In this scenario, the interior offensive line of players is used as a massive wall to block the defensive line so the quarterback can sneak around or over his men who are very resistant to being moved back.

Explanation:

Explanation:

Low-cost energy

Although building nuclear power plants has a high initial cost, it’s relatively cheap to produce energy from them and they have low operating costs.

Reliable

One of the biggest benefits of nuclear energy is that it is a reliable power generation source.

Zero-carbon emissions

Nuclear power reactors do not produce any carbon emissions. This is a huge advantage over traditional sources of energy, like fossil fuels, which releases tons of carbon dioxide into the atmosphere.

Nuclear fusion is the holy grail of harnessing energy. If we can learn to control atomic fusion (the same reactions as those that fuel the sun), we could practically have unlimited energy.

High energy density

It is estimated that the amount of energy released in a nuclear fission reaction is ten million times greater than the amount released when burning fossil fuels

Answer:

These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.
