Answer:

Large Hadron Collider

Explanation:

My favorite is the Large Hadron Collider. It is 16.6 miles and a new version is expected to be built that is 62 miles long. It is incredibly interesting to me how they are able to separate individual atoms and make them travel through the collider at light speed and then smash them into each other at these speeds. What's even more interesting is that on November 7 of 2010 they managed to create a mini-big bang that created temperatures a million times hotter than at the center of the Sun.

Answer:

The final angular speed is 16.1 rad/s

Explanation:

Given;

initial moment of inertia, I₁ = 2.56 kg.m²

final moment of inertia, I₂ = 0.40 kg.m²

initial angular speed, ω₁ = 0.4 rev/s = 2.514 rad/s

Apply the principle of conservation of angular momentum;

I₁ω₁ = I₂ω₂

where;

ω₂ is the final angular speed

ω₂ = (I₁ω₁) / (I₂)

ω₂ = (2.56 x 2.514) / (0.4)

ω₂ = 16.1 rad/s

Therefore, the final angular speed is 16.1 rad/s

Answer:

Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc. Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network's physical layer, topology, and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet).

There are several technologies used for network connections. Patch cables are used for short distances in offices and wiring closets. Electrical connections using twisted pair or coaxial cable are used within a building. Optical fiber cable is used for long distances or for applications requiring high bandwidth or electrical isolation. Many installations use structured cabling practices to improve reliability and maintainability. In some home and industrial applications power lines are used as network cabling.

Answer:

It is also called voltage.

Explanation:

Voltage in a circuits can be define as difference between two points that enable it to push a charge or current in a conducting loop there by causing light. This can also be defined as the workdone that is required per unit of charge or current to cause a motion of a test charge between the two points.

Answer:

1.) The importance of the lab in this topic is to find how dense an object is, and if it can sink or float, and it is important to answer the question so you can find the mass and volume.

2.) My hypothesis for this experiment was that the more water in the water bottle would make the beanbag fly higher. Also the higher the bottle is dropped the further it would go.

3.) The methods that I used to test my hypothesis were dropping the bottle of water from a higher distance. Another method that I used to test my hypothesis was filling the bottle with more water, or dumping water out to make it heavier/lighter.

Answer:

Newton's Second Law

Explanation:

The scenario explained above could be best described by Newton's Second Law.

Newton's Second Law state that when a net force is acted on an object, the force will lead to the acceleration of that object, such that force is equal to momentum change per change in time.

Hence, as the runner pushes harder with her leg muscles and speeds up for the last few yards, the speed is directly proportional to the force with which it pushes her leg muscles.

The image of the black body curve is missing, so i have attached it.

Answer:

T ≈ 3372 K

Explanation:

From the attached curve of the black star, if we trace the peak value of the wavelength from the graph, we will see that it is approximately 859.5 nm.

Thus; λ_peak = 859.5 × 10^(-9) m

From wiens law, we know that;

T•λ_peak = 2.898 × 10^(-3) m.K

Where T is surface temperature.

Plugging in the relevant values, we can find the temperature T

Thus;

T = (2.898 × 10^(-3))/(859.5 × 10^(-9))

T ≈ 3372 K

Explanation:

Answer:

1. Potential energy, 2. Potential and kinetic energy, 3. Potential and kinetic energy, 4. Potential and kinetic energy, 5. Potential energy

Explanation:

We note that the total mechanical energy (M.E.) of the body is given as follows;

M.E. = K.E. + P.E. = Constant

Where;

K.E. = The kinetic energy of the body = (1/2)·m·v²

P.E. = The potential energy of the body = m·g·h

m = The mass of the person

v = The velocity with which the person is in motion

g = The acceleration due to gravity ≈ 9.81 m/s²

h = The height of the person above the ground

The length of the rope = 20 m

The initial height at location 1, h₁ = 40.0 m

At location 1, the velocity, v₁ = 0.00 m/s

The mechanical energy, M.E. = K.E.₁ + P.E.₁

∴  K.E.₁ = 0 and P.E.₁ = m ×9.81×40

M.E. = (1/2) ×m ×0² + m ×9.81×40

∴ M.E. = 0 + P.E.₁ the type of energy present at location 1 is only potential energy

At location 2, the velocity, v₂ = 10.0 m/s

The mechanical energy, M.E. = K.E.₂ + P.E.₂ = (1/2) ×m ×10² + m ×9.81×40

∴  K.E.₂ = 50·m and P.E.₂ = m ×9.81×35 = 343.35·m

M.E. = 50·m + 343.35·m the type of energy at location 2 is both kinetic energy, K.E. and potential energy, P.E.

At location 3, the velocity, v₃ = 20.0 m/s

The mechanical energy, M.E. = K.E.₃ + P.E.₃ = (1/2) ×m ×20² + m ×9.81×20

∴  K.E.₃ = 200·m and P.E.₃ = m ×9.81×20 = 196.2·m

M.E. = 200·m + 196.2·m the type of energy at location 3 is both kinetic energy, K.E. and potential energy, P.E.

At location 4, the velocity, v₄² = 350.0 m²/s², h₄ = 15.0 m

The mechanical energy, M.E. = K.E.₄ + P.E.₄ = (1/2) × m ×350 + m ×9.81×15

∴  K.E.₄ = 175·m and P.E.₄ = m×9.81×15 = 147.15·m

M.E. = 175·m + 147.15·m the type of energy at location 4 is both kinetic energy, K.E. and potential energy, P.E.

At location 5, the velocity, v₅ = 0 m/s, h₅ = 10.0 m

The mechanical energy, M.E. = K.E.₅ + P.E.₅ = (1/2) × m × 0 + m ×9.81×10

∴  K.E.₅ = 0·m and P.E.₅ = m×98.1 = 98.1·m

M.E. = 0·m + 98.1·m the type of energy at location 5 is only potential energy, P.E.

Therefore, we have;

Explanation: I ended up just messing around with the numbers, I multiplied 5 and 2 got 10 as my answer and it was right.

If a force of 5 Newtons is applied to the end of a lever that has a length of 2 meters. If the force is applied directly perpendicular to the lever, then the magnitude of the torque acting on the lever would be 10 Newton meters.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem statement if a  force of 5 N is applied to the end of a lever that has a length of 2 meters. If the force is applied directly perpendicular to the lever,

The magnitude of the torque acting on the lever = 5 × 2

                                                                                  = 10 Newton meters

Thus, the magnitude of the torque acting on the lever would be 10 Newton meters.

Answer:

18 grams

Explanation:

The mass of an object is the object's fundamental property. It is the amount or quantity of mater in the object. Irrespective of the object's location or the gravitational force applied on the object, the mass of an object remains the same. In other words, the mass of an object is the same everywhere.

The mass should however not be confused with its weight which depends on the mass and the gravitational force applied on it.

In summary, whether on earth or in the moon, the mass of an object remains the same. If the mass of the object is 18 grams on earth, it will also be 18 grams in the moon.

Answer:

Positive work

Explanation:

When work and the exerted force are in the same direction, then the work done is positive.

In the question, we understand that Marvin lifts a box up (i.e. over his head). The force to lift the box acts in the upward direction and the work done itself is also in the upward direction (from the floor to Marvin's head).

Since these two are in the same direction, then we can conclude that the work done is positive.

Answer:

Q = 133.76 KJ

Explanation:

The amount of heat energy required to raise the temperature of the water can be calculated by the following formula:

[tex]Q = mC\Delta T[/tex]

where,

Q = Heat Energy Required = ?

m = mass of water = 2 kg

C = Specific Heat Capacity of Water = 4.18 KJ/kg°C

ΔT = change in temperature = 26°C - 10°C = 16°C

Therefore,

[tex]Q = (2\ kg)(4.18\ KJ/kg.^oC)(16^oC)[/tex]

Q = 133.76 KJ

Answer:

change

Explanation:

Energy can be defined as the ability (capacity) to do work or cause change in a system.

The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.

Energy is the ability to do work or cause change.

Basically, the various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.

The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.

Mathematically, it is given by the formula;

Mechanical energy = G.P.E + K.E
