Look at the diagram showing resistance and flow of
electrons.
OX: High resistance
Y: Low resistance
Z: Flow of electrons
X
N
X: Low resistance
Y: Flow of electrons
Z: High resistance
0 X: Flow of electrons
Y: High potential energy
Z: Low potential energy
X: Low potential energy
Y: High potential energy
Z: Flow of electrons

Answers

Answer 1

Answer: D

Explanation: Look at the figure, we can conclude that the correct answer is

X: Low potential energy

Y: High potential energy

Z: Flow of electrons

Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.

Since the arrow is pointing to X, that means

Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.

Why does a nucleus always have a positive charge?

Answers

Answer:

Explanation:

The nucleus is positive because only protons live in the nucleus. Electrons (which have a minus charge ) orbit around the nucleus, but only the nucleus has positive charges.

It contains protons- which always have a positive charge, causing the nucleus to constantly be positively charged

Foliation occurs when minerals are flattened by heat and pressure. this results in a layered or banded texture. What type of rock do you think is foliated?

Answers

Visible silicate minerals split into dark and light bands or lineations in a metamorphic foliation known as gneissic banding. Typically coarse and frequently folded, these grains. Gneiss is the name for a rock with this texture.

Foliated Metamorphic Rocks:
Some kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.)

Answer:

The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates.

The greater the __ and __ the more kinetic energy there will be. (Fill in the blanks)

Answers

Answer  the gerater mass and the faster the object moves the more kenetic enegry there would be

Explanation:

Answer:

The greater the mass and acceleration the more kinetic energy there will be.

Kinetic energy and Explanation

The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Mass and Explanation

Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.

Acceleration and Explanation

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Use the data in the table to explain how you could determine the volume of the block.

Use the data in the table to explain how you could determine the volume of the block.

Answers

To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.

To find the volume of the block using the measurements provided.

1. Calculate the change in water volume:

The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.

2. Convert the change in water volume to cubic centimeters:

Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.

3. Determine the volume of the block:

When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.

By following these steps, we can find the volume of the block based on the provided measurements.

Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

Explain what happens as the heart grows bigger.

Answers

When the heart grows bigger, a condition known as cardiac hypertrophy occurs. This can happen as a result of several factors, including high blood pressure, heart disease, and obesity.

Initially, the heart may grow bigger as a compensatory mechanism to try to keep up with increased demands for blood and oxygen. For example, if a person engages in regular exercise, their heart may enlarge to accommodate the increased demand for blood and oxygen to the muscles.

However, if the heart continues to grow over time, it can become less efficient at pumping blood and may develop structural abnormalities that increase the risk of heart failure, arrhythmias, and other complications.

In some cases, cardiac hypertrophy may be reversible if the underlying cause is treated, such as by managing high blood pressure or heart disease. However, if left untreated, hypertrophy can lead to irreversible damage to the heart muscle and may require more aggressive interventions, such as medication, surgery, or other medical procedures to manage the condition.
An enlarged heart may cause the heart to beat too fast or too slow. The irregular heartbeat (arrhythmia) may lead to fainting, cardiac arrest or sudden death.

Answers

It states that the time rate of change of the velocity (directed speed), or acceleration, , is directly proportional to the force F and inversely proportional to the mass m of the body; i.e., a = F / m or F = ma; the larger the force, the larger the acceleration (rate of change of velocity); the larger the mass, the smaller the acceleration.

Answers

Metamorphic Rock - Forms when pressure, temperature, or chemical processes change existing rock. Igneous Rock - forms when magma or lava cools and hardens to become solid. Sedimentary Rock - Form when minerals that form from solutions or sediment from older rocks get pressed and cemented together. The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble.
