"The Large Hadron collider (LHC) is a huge piece of equipment designed and built in order to make new scientific discoveries."

As we know that there are two types of planets in our solar system, the terrestrial and jovian planets. Terrestrial planets are the planets that are made up of rock or metal and are much denser and smaller than the jovian planets.

The jovian planets are the planets that are made up of gases and are much larger and less dense than the terrestrial planets. Now let's talk about the number of moons each planet has. Each of the six terrestrial planets has at least five moons, while the jovian planets have no moons at all.

The planets of the solar system have been classified into two categories. The first type of planets is the terrestrial planets, also known as rocky planets, and the second type is the jovian planets, also known as gas giants. The terrestrial planets are smaller, denser, and composed mostly of rock and metal. On the other hand, the jovian planets are larger, less dense, and mostly composed of gases such as hydrogen and helium. As per the given question, a solar system has six terrestrial planets and four jovian planets.

Each of the six terrestrial planets has at least five moons, while the jovian planets have no moons at all.This implies that the terrestrial planets are much more likely to have moons than the jovian planets. It is because the gravitational pull of a planet depends on its size and mass. A smaller planet will have less gravitational pull, which means it can easily capture and hold onto a moon in its orbit. In contrast, a larger planet will have a stronger gravitational pull, which can cause it to lose moons or not capture any at all. Therefore, the terrestrial planets can hold onto moons better than the jovian planets.

The number of moons a planet can have depends on its size, mass, and gravitational pull. The terrestrial planets in our solar system have a higher likelihood of having moons because they are smaller, denser, and have less gravitational pull than the jovian planets. The jovian planets have no moons at all because they are larger, less dense, and have a stronger gravitational pull that can cause them to lose moons.

If earth shrank, and mass remains unchanged, then my weight at the surface will increase.

We know very well that weight of the body is given (W)=mg, where m is the mass of the body and g is the acceleration due to gravity.

Also, acceleration due to gravity(g)=GM/r²,

When earth shrank, in that case radius will decrease, due to that acceleration due to gravity will increase.

We move more closer to the center of gravity, and due to higher value of g our weight will increase.

Hence, my weight will increase.

Answer: Elements in the same group

Answer:

a) 37.5N

b) 9.375Joules

Explanation:

a) According to Hooke's law

F = ke

k is the spring constant

e is the extension;

F = 150 * 0.25

F = 37.5N

b) Work done on the spring = 1/2ke^2

Work done on the spring = 1/2 * 150 * 0.25^2

Work done on the spring  = 75 * 0.0625

Work done on the spring  = 9.375Joules

(a)  The force required to stretch the spring is of 37.5 N.

(b)  The work done on the spring is of 4.6775 J.

Given data:

The force constant of a spring is, k = 150 N/m.

The stretching distance of spring is, x = 0.25 m.

(a)  

When some force is experienced on the spring, then due to this force then it will displace. Then, the expression for the force applied on the spring is given as,

\(F = k \times x\)

Solve by substituting the values as,

\(F = 150 \times 0.25\\\\F = 37.5 \;\rm N\)

Thus, we can conclude that the force required to stretch the spring is of 37.5 N.

(b)

And the expression for the work done on the spring is given as,

\(W = \dfrac{1}{2}kx^{2}\)

Solving as,

\(W = \dfrac{1}{2} \times 150 \times 0.25^{2}\\\\W = 4.6875 \;\rm J\)

Thus, we can conclude that the work done on the spring is of 4.6775 J.

The result is added to the initial height of 15 meters to obtain the height of the capsule at any given time.

To determine the number of rotations each capsule makes in a given time, we need to convert the time to minutes and divide by the time it takes for one full rotation.

In 1 hour (60 minutes), each capsule will make 60 minutes / 30 minutes = 2 rotations.

In 2 hours (120 minutes), each capsule will make 120 minutes / 30 minutes = 4 rotations.

In t hours (t × 60 minutes), each capsule will make (t × 60 minutes) / 30 minutes = (2×t) rotations.

To calculate the number of radians each capsule sweeps in a given time, we need to multiply the number of rotations by 2π (since one full rotation is equal to 2π radians).

In 1 hour, each capsule will sweep 2 rotations × 2×π radians = 4π radians.

In 2 hours, each capsule will sweep 4 rotations × 2×π radians = 8π radians.

In t hours, each capsule will sweep (2×t) rotations × 2×π radians = 4tπ radians.

The height of a capsule can be determined using the following equation:

H_(t) = 15 meters + (t × 30 minutes × (165 meters - 15 meters) / (60 minutes))

In this equation, t represents the time in hours since the capsule boarded. The term (t × 30 minutes) converts the time to minutes, and the division by (60 minutes) converts it back to hours. The expression (165 meters - 15 meters) represents the total vertical distance the capsule can travel, and it is multiplied by the ratio of the elapsed time to the total time for one full rotation. The result is added to the initial height of 15 meters to obtain the height of the capsule at any given time.

The total change of mechanical energy in the system is negative and is equal to \(-(3/2)mv^2\).

The total change of mechanical energy in the system can be calculated by finding the initial mechanical energy of the system and subtracting the final mechanical energy.

The initial mechanical energy of the system is:

\(E_i = (1/2)mv^2 + (1/2)(2m)v^2 = (1/2)mv^2 + mv^2 = (3/2)mv^2\)

Since the blocks are moving in opposite directions, they will collide and stick together. After the collision, the combined mass will be 3m and the velocity will be zero. The final mechanical energy of the system is:

\(E_f = (1/2)(3m)(0)^2 = 0\)

The total change of mechanical energy in the system is:

\(ΔE = E_f - E_i = - (3/2)mv^2\)

Therefore, the total change of mechanical energy in the system is negative and is equal to \(-(3/2)mv^2\). This indicates that some energy was lost during the collision, possibly due to friction or deformation of the blocks.

The work function of the metal surface is 6.03 × 10^-19 J. The unit of work function is joules (J).

The photoelectric effect is the phenomenon of emission of electrons from a metal surface when light falls on it. When light of a certain frequency (or wavelength) falls on the metal surface, electrons are emitted from the surface. The minimum frequency (or wavelength) of the incident light required to eject an electron is called the threshold frequency (or wavelength).

Now, in the given experiment, it is found that no current flows unless the incident light has a wavelength shorter than 331 nm. This means that the threshold wavelength of the metal surface is 331 nm. We can use the following equation to relate the threshold wavelength to the work function:

λ_threshold = hc/Φ

where λ_threshold is the threshold wavelength, h is Planck's constant, c is the speed of light, and Φ is the work function.

Rearranging the above equation, we get:

Φ = hc/λ_threshold

Substituting the values, we get:

Φ = (6.626 × 10^-34 J s) × (3 × 10^8 m/s) / (331 × 10^-9 m)

First of all, Slope of a Displacement time graph represents velocity. so we can say that :

Graph has positive (increasing) Slope from 3rd to 6th seconds that represents positive constant velocity.

From 6th to 8th second graph has Slope = 0, that means there is no Displacement taken in the mean time, that means velocity in this interval of time is 0.

From 8th second the graph has negative (Decreasing) Slope that means, the object is retracing its own path with a constant velocity.

This is because a thermometer is only meant for measuring temperature and temperature is not a measure of thermal energy

Explanation:

The reason is because a thermometer is designed and calibrated to measure the temperature of a body.

Although the thermal energy of a body is somehow related to its temperature, the thermal energy of a body is not entirely dependent on the temperature of the body

The thermal energy of a body deals with its heat. While thermal energy basically deals with the amount of heat, temperature deals with the flow from one point to another along the body

So what this means is that since thermometer measures this flow, it cannot be used to ascertain the level of heat ( thermal energy) in the body

If gravity is unimportant and the value of h (Hubble constant) is 75 km/sec/mpc, the estimated age of the universe using the Hubble constant would be approximately 13.8 billion years.

The Hubble constant (h) represents the rate at which the universe is expanding. By assuming gravity to be unimportant, the age of the universe can be estimated using the Hubble constant. The formula for calculating the age of the universe is 1/h, where h is measured in units of km/sec/mpc (kilometers per second per megaparsec). With a given Hubble constant of 75 km/sec/mpc, the estimated age would be approximately 1/75 billion years, which is roughly 13.8 billion years. This estimate is based on the assumption of a constant rate of expansion throughout the history of the universe and provides a rough approximation of its age.
