If there is two batteries connected in series, each battery is 6V. What is the EMF of the battery?​

Answers

Answer 1

Answer:

The EMF of the batteries connect in series in the circuit is 12 V.

Explanation:

Given;

two batteries, each is 6 V

The EMF of the batteries connect in series in the circuit is calculated as sum of the voltage of the two batteries since they are connected in series.

EMF = V₁ + V₂

EMF = 6V + 6V

EMF = 12 V

Therefore, the EMF of the batteries connect in series in the circuit is 12 V.

The _____ composition of igneous rocks can vary because of the different minerals that might be contained within the rock.

Answers

Mineral composition is a crucial factor in determining the type of igneous rock. Igneous rocks are formed from the solidification of magma or lava, and the mineral composition of the rock is determined by the chemical composition and cooling conditions of the magma.

The mineral composition can vary greatly, depending on factors such as the chemical makeup of the magma, the pressure and temperature conditions during cooling, and the presence of other minerals or impurities.

For example, granitic magma, which is rich in silica and has a low content of other elements, will solidify into a rock with a high concentration of quartz and feldspar minerals. On the other hand, basaltic magma, which is low in silica and high in iron, magnesium, and other elements, will solidify into a rock containing mostly pyroxene, olivine, and plagioclase minerals.

________ occurs in the summer months, while ________ occurs in the winter.

Answers

Estivation occurs in the summer months, while hibernation occurs in the winter.

How is hibernation and estivation similar?

Both hibernation and estivation involve an animal's metabolism slowing down, and the animal appears to be dead because of how slowly it breathes. Similar to how humans hibernate in the winter, estivating can be defined as staying put and not traveling during the summer.

What is the most basic division of animals based on?

True animals can be broadly categorized into three groups based on the symmetry of their body plans: radially symmetrical, bilaterally symmetrical, and asymmetrical, at the most fundamental level of classification. Two contemporary clades, the Parazoa (Figurea) and Placozoa, exhibit asymmetry.

what is the Difference Between Aestivation And Hibernation ?

Animals engage in hibernation, sometimes known as "winter sleep," which is a condition of inactivity or low metabolic activity. On the other hand, aestivation, or "summer slumber," is the animals' low metabolic rate throughout the summer.

some rivers have a daily cyclical pattern in discharge where discharge increases and decreases regularly as shown in the hydrograph. what is the reason for the regular repeating pattern?

Answers

The daily cyclical pattern in river discharge is caused by factors such as snowmelt, evapotranspiration, groundwater influence, and human activities.

How is the regular repeating pattern of river discharge explained?

The regular repeating pattern of daily cyclical discharge in rivers can be attributed to a phenomenon known as diurnal or daily hydrological fluctuations. Several factors contribute to this pattern:

Snowmelt and Glacial Runoff: In regions with snow or glaciers, the daily temperature variation causes snow or ice to melt during the day, increasing the discharge. At night, with cooler temperatures, the melting process slows down, leading to decreased discharge.

Evapotranspiration: During the day, higher temperatures and sunlight promote evaporation from the river and surrounding vegetation. This reduces the amount of water in the river, resulting in lower discharge. At night, evaporation rates decrease, allowing discharge to increase.

Groundwater Influence: Groundwater contributes to river flow. During the day, evapotranspiration rates increase, leading to a drawdown of groundwater levels, which reduces river discharge. At night, with reduced evapotranspiration, groundwater levels rise, resulting in increased river discharge.

Human Activities: Human activities, such as water withdrawals for irrigation or industrial use, can also contribute to the daily cyclical pattern. Higher demand during the day leads to reduced river flow, while decreased demand at night allows for increased discharge.

It's important to note that the specific factors contributing to the daily cyclical pattern may vary depending on the geographical location, climate, and local hydrological conditions of a particular river.

the forces that deform rock are different in different directions and are referred to as .

Answers

The forces that deform rock in different directions are referred to as stress. Stress can be defined as the force per unit area acting on a material.

When rocks are subjected to stress, they can undergo different types of deformation, including compression, tension, and shearing. Compression occurs when rocks are squeezed together, while tension occurs when rocks are pulled apart. Shearing occurs when rocks are pushed in opposite directions along parallel planes. The type of deformation that occurs depends on the type of stress and the strength of the rock. Over time, this deformation can lead to the formation of geological structures such as faults, folds, and mountains.

1. what are the two basic features of a fault and how would you differentiate between them?

Answers

The two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. The surface of the Earth is covered by a network of large cracks known as faults.

The earth's crust is in motion, which causes pressure to accumulate on the rocks, and this leads to the development of cracks that may result in earthquakes. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks. A fault occurs when two large blocks of the earth's crust shift position relative to one another. The movement of the rocks, as well as the direction in which they move, determine the type of fault. There are two types of faults based on their motion, namely, normal faults and reverse faults. A normal fault is characterized by the hanging wall moving downward relative to the footwall. The hanging wall is the block of rock that lies above the fault plane, while the footwall is the block of rock that lies below the fault plane. When the stress that created the fault is greater than the friction holding the rocks together, the rocks break apart, causing the hanging wall to move downward relative to the footwall.

On the other hand, reverse faults occur when the hanging wall moves upward relative to the footwall. Reverse faults are also called thrust faults, and they occur when rocks are under compression, and the hanging wall moves up. The hanging wall is usually moved up over the footwall. The reverse fault has an angle that is steeper than 45°.

In conclusion, the two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks.

In ΔNOP, the measure of ∠P=90°, OP = 99 feet, and PN = 86 feet. Find the measure of ∠N to the nearest degree.

Answers

Answer:

<N = 49°

Explanation:

This question isn't geography; it's mathematics.

However, the solution is as follows.

This question is best answered using an attachment (see attachment)

Given that

<P= 90° (This shows that the triangle is right angled)

PN = 86ft

OP = 99ft

Required

Angle <N

From the triangle below, we're to solve for θ

The side opposite θ = 99

The side adjacent θ = 86

In other words,

Opp = 99

Adj = 86.

The relationship between θ, Opp and Adj is tan and this is defined as follows.

Tan θ = Opp/Adj

Substitute 99 for Opp and 86 for Adj

Tan θ = 99/86

Tan θ = 1.1512

Take inverse tan of both sides

θ = arctan(1.1512)

θ = 49.02°

θ = 49° (Approximated)

Hence, the measure of <N is 49°

In NOP, the measure of P=90, OP = 99 feet, and PN = 86 feet. Find the measure of N to the nearest degree.

Answers

Answer:

True

Explanation:

It is TRUE that the larger the scale interval on the vertical axis, the smaller the difference between bars.

The above statement is true because a higher or larger scale interval ensures that a huge quantity can be covered. For example 1:200, 1:500, 1:1000, 1:2000. Hence, the difference in height of different bars, for example, 1:2000 will be very smaller compared to the difference in height of 1:200 bars.

a sequence of folded rocks must be older than the event that deformed them. this is an example of the principle of: group of answer choices original horizontality inclusions superposition lateral continuity

Answers

A sequence of folded rocks must be older than the event that deformed them. This is an example of the principle of original horizontality.

According to the Law of Original Horizontality, all rock strata were initially deposited horizontally and are therefore susceptible to deformation. This enables us to deduce that for the rocks to be slanted, something must have occurred to them. This comprises quakes, faulting, and mountain-building activities. The lower rock strata are slanted as a result of deformation. The top rock strata are once more placed level since they were added after the tilting event.

The conclusion of the science of plate tectonics, which holds that movement and collisions of huge plates of the Earth's crust are what causes folded rock strata, is further supported by evidence that the Earth has not been static and that powerful forces have been at work over extended periods of time.

D. Machines replaced people in many factory jobs, forcing them to

Answers

Answer:

C. Lack of regulation led to long hours, low pay, and dangerous

working conditions.

Explanation:

The Industrial Revolution represented an enormous change in the working conditions of most of the working class. In fact, it is only after the Industrial Revolution that we talk of a "working class", since before, most people of low social status were peasants.

During the first decades of the Industrial Revolution, labor was mostly unregulated, and firms took advantage of this by exploiting their workers as much as possible, making them work very long hours, with little pay, and under dangerous or harsh conditions.

This prompted the birth of social movements and workers' unions, who demanded better working conditions, like better pay, a 8 hour daily shift, and vacation time. With time, in most countries in the world these demands became laws, which means that nowadays working conditions are much better.
