Earth's orbit is currently elliptical enough to make the intensity of sunlight vary by 6 percent. the largest earth-sun distance occurs in every january.

When seen from above the Northern Hemisphere, the Earth circles the Sun at an average distance of 149.60 million kilometres in a counterclockwise manner. Earth has travelled 940 million kilometres in 365.256 days, the length of one orbit. Every twelve months, the earth orbits the sun. With the sun at one of the ellipse's foci, the orbit has a slightly elliptical form. A plane with the sun in it is defined by the orbit. It takes the Earth 149 million kilometres to travel to the sun on average. The path taken by Earth is not a perfect circle. It is oval-shaped, or elliptical. This implies that Earth is closest to the Sun at a certain point in its orbit, and farthest from the Sun at an other point.

7 moles of CH₄ are contained in 112 g of that substance.

The weight of a single mole of a substance is its molar mass. The word "molar mass" refers to the amount of a certain chemical in grams that makes up one mole. The periodic table contains a list of the atomic masses that were utilized to compute the molar mass. The Avogadro's number reveals the number of particles in each mole.

The molar mass, also referred to as the molecular weight, is the total mass of the atoms needed to create a molecule per mole, represented in grams. Grams per mole are used to express molar mass.

Given mass = 112 g

Molar mass of CH₄ = ( 1 x 12 ) + ( 4 x 1) = 16 gmol-1

Number of moles = mass / Molar mass

Number of moles = 112 g / 16 gmol-1

Order of the three bars from the lowest to the highest melting point of the materials can be arranged from bottom to top as given below

(c) Lowest melting point - high intermolecular forces

(b) Intermediate melting point - medium intermolecular forces

(a) Highest melting point - low intermolecular forces

The matter has three different states and all of them have different melting points depending on the type of intermolecular forces in them.

So far, the melting point of a substance refers to the point or temperature at which it undergoes the transition phase to turn from a solid to a liquid state.

When a substance starts melting it reaches the intermediate point or the equilibrium point where the solid and liquid phases co-exist.

The melting point also depends on the atmospheric pressure standard is 100 kilopascal or 100 Kpa.

In general, a substance passes through three phases of melting point i.e. at first the melting point is lowest, then reaches to equilibrium point or intermediate point, and then to the highest point where it completely melts overcoming the intermolecular forces.

Based on data in the chart, it can be concluded that as the mass increases then the thermal energy increases because thermal energy of a substance depends greatly on the temperature and mass of that substance

Thermal energy always moves from an area with a higher temperature to an area with a lower temperature. So, if  a block of ice comes in contact with a substance that has  lower temperature, such as liquid nitrogen or dry ice, then thermal energy move from the ice to the colder substance.

Mass measures the quantity of material in a sample ,therefore, thermal energy depends on the mass and the temperature of the object. The more the mass of the object,  more particles are in the sample and   thermal energy is also more.

The average force necessary to stop a hammer having momentum of 25 NS , in 0.05 second is 500N.

What is Momentum?

Momentum is the product of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum. The rate of change of a body's momentum is equal to the net force exerted on it, according to Newton's second law of motion. Regardless of the frame of reference, momentum is a conserved quantity in any inertial frame, which means that if an enclosed system is not subject to outside influences, its total linear momentum remains constant. Additionally, momentum is preserved in general relativity, electrodynamics, quantum mechanics, quantum field theory, and special relativity (using a modified formula). It is a manifestation of translational symmetry, one of the basic symmetries of space and time.

Minimum speed is necessary to clear the canyon is 14 m/s

What is speed ?

The speed of an object, also known as v in kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time, making it a scalar quantity. The instantaneous speed is the upper limit of the average speed as the duration of the time interval gets closer to zero. [1] The average speed of an object in a period of time is the distance travelled by the object divided by the duration of the interval. Velocity and speed are not the same thing.

The parameters of speed are time divided by distance. The most often used unit of speed in daily life is the kilometre per hour (km/h), or miles per hour in the US and the UK. The SI's unit of speed is the metre per second (m/s) (mph). The knot is frequently utilised for maritime and air transport.

Since the object falls freely without being pushed, we are able to conclude it falls with constant acceleration.

The Final Velocity of the space - mobile would be the total displacement it covered in the given time.

Final Velocity = 96/4 m/s

Explanation:

Tension is the result of opposite forces in a connector. The tension pulls each object towards the center of the connector. Thus, the given statement is true.

Tension is the opposite force that is exerted by a rope, string, cable, or similar object on one or more objects. Anything which is pulled, hung, supported, or swung from a rope, string, and cable, etc. is subjected to the tension force. Like all the other forces, tension can also accelerate objects or cause them to deform from their original structure.

Newton's third law is that when a contact force acts between any two objects, both the objects experience the same magnitude of force, but in opposite directions to each other. In tension, the two objects which are attached with the rope pull on each other.

To determine the magnitude of tension, a formula is used:
