Jennifer runs 5 miles east, then stops to take a break. after her break, she continues running 4 more miles east. what is her distance and displacement?

The mass of the object is 6 kg.

Any push or pull applied to an object is termed a force. In other words, force is defined as the product of the mass of the object and its acceleration. SI unit of force is Newton and that is denoted by the symbol N. Force is termed as a vector quantity because it has both magnitude and direction.

[tex]Force = Mass × Accleration [/tex]

[tex] F = m × a[/tex]

Acceleration is defined as the rate at which velocity changes an object over time.

Si unit of the acceleration is a meter per second square.

[tex]Accleration = \frac{Velocity}{ Time}[/tex]

[tex]a = \frac{v}{t} [/tex]

Acceleration = 6 m/s²

Force = 36 N

The mass of the object is,

[tex]F = m × a[/tex]

[tex]36 = m \times 6[/tex]

[tex]m = \frac{36}{6} [/tex]

[tex]m = 6 \: kg[/tex]

Therefore, the mass of the object is 6 kg.

During the time that a planet is in its period of apparent retrograde motion, over many weeks or days, the planet moves west relative to the stars, rather than the usual east relative to the stars

All the planets orbit the Sun in the exact direction, and if you envision a place above the Earth's north pole, you can see them traveling anticlockwise. The normal motion is anticlockwise and is recognized as 'prograde.'

When a planet is in apparent retrograde motion, it appears to be the planet moving west relative to the stars, rather than the usual east relative to the stars, frequently zigzagging or looping as it goes. The planet appears to be moving backward to the viewer. The word "retrograde" means "to move backward."

An artwork from The Book of Fixed Stars is seen in the figure.

A man is depicted in the drawing holding a sickle with his left hand and extending his right arm forth. The person is hunched over on his left knee, and above him is inscribed in Arabic calligraphy. There are dots all throughout the artwork with Arabic text that identify specific stars and their brightness as observed by Muslim astronomers.

The monarch of the Turkic Timurid dynasty, which ruled over a large portion of Central Asia in the fifteenth century, received this copy of The Book of Fixed Stars. Individual stars are represented by the dots spread throughout the picture, and the symbols next to the dots denote the stars' varying luminosities,  as observed by Muslim astronomers.

The greatest evidence that intellectual activities in the Muslim world persisted in the era between 1200 and 1450, despite the dissolution of the Abbasid Caliphate, is the sponsorship of scholarship by Turkic dynasties, such as the Timurids.

The demand for widgets has a price elasticity of 0.5. If we assume no change in the demand curve for widgets, an increase in sales of 8 percent implies a(n) 32% reduction in price.

The basic formula for the price elasticity of demand coefficient is:

Percentage change in quantity being demanded/percentage change in the price

Demand elasticity the price elasticity of demand (PED) of a good is a measurement of how responsive the quantity demanded is to the price.

Almost all goods see a decrease in quantity demanded when prices rise, however certain goods experience this decrease more than others.

When a price increases by 1% while all other factors remain constant, the price elasticity provides the percentage change in the quantity required. If the elasticity is 2, a 1% increase in price results in a 2% decrease in the amount demanded.

Other elasticities gauge how changes in other factors affect the quantity needed (e.g., the income elasticity of demand for consumer income changes).

A hockey puck is set in motion across a frozen pond, if friction and air resistance are ignored, zero newton force is required to keep the puck sliding at constant velocity .

The force preventing solid surfaces, fluid layers, and sliding material components from moving in the same direction is known as friction. Friction between two surfaces causes kinetic energy to be converted into thermal energy when they move in relation to one another (that is, it converts work to heat). The utilization of friction produced by rubbing pieces of wood together to start a fire serves as an example of how this attribute can have dramatic effects. When a viscous fluid is agitated, for instance, kinetic energy is transformed into thermal energy.

This law applies to bodies in uniform or rapid motion and is crucial for addressing problems of static equilibrium, where all forces are in balance. The forces it discusses are actual phenomena, not just accounting tricks.

If there is a net force operating on a body, it moves faster in line with the second rule.

If there is no net force acting on the body, either because there are no forces at all or because all forces are precisely balanced by opposing forces, the body does not accelerate and is said to be in equilibrium.

The fusion of hydrogen nuclei in stars produced all of the helium in the Universe.

However, most stars undergo an internal transformation after turning a considerable percentage of their hydrogen to helium. The interior core compresses and warms up until it is hot enough to fuse helium into bigger atoms, for as by fusing three helium atoms into carbon. At the same time, some helium will combine with the carbon to generate oxygen. Outside the core, in what is known as the envelope, there is still enough hydrogen to fuse into additional helium. However, the center starts fusing heavier nuclei. This, by the way, is the transition from a 'regular' star like our Sun to a Red Giant.

After the red giant phase, the Sun will shed its outer layers, leaving behind a helium-rich core that will gradually cool throughout the course of the Universe. After the red giant phase with stars more massive than the Sun, it becomes practically a free for all for producing heavier and heavier atoms. When the helium in the core runs out, the star collapses again, heats up, and begins fusing carbon and oxygen into bigger atoms. If the star is large enough, this will continue until iron is fused. At such time, a hotter core will still not result in fusion. The star falls, becomes unstable, and explodes, resulting in supernovae and neutron stars (or black hole).
