The given problem can be exemplified in the following diagram:

To determine the extension force we will use the definition of pressure:

Where "F" is the force, and "A" is the area. To determine the area we will use the following equation:

Where "D" is the diameter. The force acts over the area of the 10 inches diameter alone, therefore we don't need to have into account the area of the rod. Replacing the value of the diameter we get:

Solving the operation:

Replacing in the formula for the pressure we get:

Since we are required to determine the force, we will multiply both sides by the area:

Replacing the given value of the pressure we get:

Solving the operations we get:

Therefore, the extension force is 107756.62 lbf.

The total distance of Bella's trip through the jungle is 24 kilometers.

To find the total distance of Bella's trip, we need to calculate the distance traveled during each leg of her journey and then sum them up.

Let's calculate the distance traveled in each segment:

Trekking in the thick jungle:

Bella trekked for 1 hour at an average speed of 6 km/h.

Distance = Speed × Time

Distance = 6 km/h × 1 hour

Distance = 6 km

Crossing the lake by boat:

Bella rode a boat at an average speed of 20 km/h for 0.5 hours.

Distance = Speed × Time

Distance = 20 km/h × 0.5 hour

Distance = 10 km

Hiking for the remaining part:

Bella hiked for 2 hours at an average speed of 4 km/h.

Distance = Speed × Time

Distance = 4 km/h × 2 hours

Distance = 8 km

Now, let's calculate the total distance:

Total distance = Distance of trekking + Distance of crossing the lake + Distance of hiking

Total distance = 6 km + 10 km + 8 km

Total distance = 24 km

A polar covalent bond is one where electrons are unequally shared between the atoms in the bond. option (c)

In a covalent bond, atoms share electrons to form a stable compound. However, in some cases, the electrons are not shared equally between the atoms, resulting in a partial positive charge on one atom and a partial negative charge on the other. This unequal sharing of electrons occurs when one atom has a higher electronegativity (ability to attract electrons) than the other. The atom with higher electronegativity attracts the electrons closer to itself, resulting in a partial negative charge on that atom, while the other atom has a partial positive charge. For example, in the water molecule (H2O), the oxygen atom is more electronegative than the hydrogen atoms. As a result, the electrons in the covalent bond are pulled closer to the oxygen atom, giving it a partial negative charge, while the hydrogen atoms have a partial positive charge.

Polar covalent bonds play an essential role in many biological processes, such as the formation of DNA and proteins, and are crucial in understanding the properties of many chemical compounds. option (c)

Answer:

S = 16.3125m

Explanation:

Given the following data;

Acceleration, a = 14.5m/s²

Time, t = 2.25secs

Since the bottle rocket starts from rest, its initial velocity is 0m/s.

To find the distance S, we would use the second equation of motion.

S = ut + ½at²

Substituting into the equation, we have

S = 0(2.25) + ½*14.5*2.25

S = 0 + 7.25*2.25

S = 16.3125m

Therefore, the bottle rocket covered a distance of 16.3125 meters.

(1) The distance of the image formed by the lens is determined as 6 cm.

(2) The image formed is real.

The distance of the image formed by the lens is calculated by applying the following formula as follows;

1/f = 1/v + 1/u

where;

The distance of the image formed by the lens is calculated as;

1/v = 1/f - 1/u

The remaining battery capacity would be 76%, which is still above the 25% limit on discharge depth.

If the electric bicycle can go 100 miles on a full charge, and the owner wants to limit the discharge depth to 25%, then they can only use up to 25 miles of the battery's capacity before needing to recharge.

Since the owner's commute is 12 miles round trip, they can make one round trip without depleting the battery more than 25% of its capacity.

Therefore, the owner can make 2 round trips (2 x 12 = 24 miles) before needing to recharge, but they will still have some battery capacity left.

The remaining battery capacity would be (100 - 24)/100 x 100% = 76%, which is still above the 25% limit on discharge depth. So the owner could make a few more round trips before needing to fully recharge the battery.

The density of the liquid in the drum is 459.184 kg/m³.

To find the density of a liquid, we must know its pressure, the depth to which it is filled, and the gravitational acceleration acting on it. Using the equation for pressure at a depth h below the surface of a liquid in a container of height H, P = ρgh, where P is the pressure, ρ is the density, g is the gravitational acceleration, h is the height of the liquid, and H is the height of the container.Let's substitute the given values in the above formula:P = 9000800 Pa; h = 2m; g = 9.8m/s²Therefore, ρ = P/gh = 9000800/(9.8 × 2) ≈ 459184.

This means that the density of the liquid in the drum is 459.184 kg/m³ (kilograms per cubic meter).

Palace word best provides a context clue to the meaning of mead-hall. So, the correct option is A.

The royal residence, as well as occasionally a place of government or worship, is referred to as a palace. The Pontifical Hill in Rome, where the Ancient romans built their palaces, is whence the word was from.

A palace should be distinguished from a fortress, which was formerly any fortified residence, as a construction. A palace is a location with a regal and imposing structure that serves as a stately home such as a president, ruler, or leader's official residence.

Many old palaces have been turned into museums that depict what life was like for the king and aristocracy at the time they were erected. The context information provided by Palace term in the aforementioned example sheds light on the definition of mead-hall.

Gerard's average velocity for the ride is 6 meters per second.

To find Gerard's average velocity for the ride, we can use the formula:

Average velocity = Total displacement / Total time

First, we need to convert the distance traveled from kilometers to meters:

7.20 kilometers * 1000 = 7200 meters

Next, we convert the time from minutes to seconds:

20.0 minutes * 60 = 1200 seconds

Now, we can calculate the total displacement by subtracting the initial position from the final position. Since Gerard is riding directly east, there is no change in the east-west direction, so the displacement is equal to the distance traveled:

Total displacement = 7200 meters

Finally, we substitute the values into the average velocity formula:

Average velocity = 7200 meters / 1200 seconds

Average velocity = 6 meters per second

Mendel's law of segregation states that an individual inherits one allele for each trait from each parent and that these two alleles segregate during gamete formation, with each gamete containing only one allele of each gene.

Mendel's law of segregation states that an individual inherits one allele for each trait from each parent and that these two alleles segregate during gamete formation, with each gamete containing only one allele of each gene.

The other two laws of Mendelian inheritance are:

Mendel's law of independent assortment: states that the inheritance of one trait is independent of the inheritance of another trait if the genes encoding the traits are on different chromosomes or are far apart on the same chromosome.

Mendel's law of dominance: states that when two different alleles are present in an individual, one allele (the dominant allele) will be expressed, while the other allele (the recessive allele) will be masked.

Research helps further the biological perspective when they demonstrated that electrical activity in the brain can predict an individual's behaviour.

Behaviour is the way in which an individual or group acts and reacts to events, people, and their environment. It is the actions of an individual or group and the reactions they cause in others. Behaviour can be conscious or unconscious, voluntary or involuntary, and is often defined in terms of being either adaptive or maladaptive.

This concept, known as neuropsychology, provides evidence that behavior is largely determined by biological processes and can help explain the complex relationships between the brain and behavior. Neuropsychological research has allowed scientists to better understand the neural basis of behavior, allowing a more.
