Answer:
The description of the given scenario is described in the explanation segment below.
Explanation:
As a charge passes through some kind of potential gap, the electrical task is undertaken as well as energy will be transferred. The Potential difference seems to be an amount of work performed per unit charge and is denoted by "V" as well as a charge is denoted by "Q".The energy transferred could be determined by using the following equation or formula:
⇒ Energy transferred = charge × potential difference
The equation that links energy transferred, charge flow, and potential difference (voltage) is: [tex]E = qV[/tex]
In Science, when a potential difference (voltage) is applied on an object, it gains some potential energy, which is then converted to kinetic energy.
The kinetic energy possessed by the object is responsible for the movement of electrons from one point to another in an electric field.
Hence, the quantity of energy in an electric circuit is directly proportional to the charge and potential difference (voltage) applied on the object.
Mathematically, the energy transferred in an electric field is given by the formula:
[tex]E = qV[/tex]
Where:
E is the energy transferred.q is the charge.V is the potential difference.Read more: https://brainly.com/question/23153766

A vector points 12.0 units along the x-axis, and 9.00 units along the y-axis. Find the direction of the vector
The resultant points somewhere between the positive x and y axes.
The angle it makes with the x-axis has a tangent of (9/12) = 0.75 .
That angle is 36.9°, rounded to the nearest tenth of a degree.
So the resultant vector points up and to the right, 36.9° above the x-axis.
Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.
Answer:
D
Explanation:
Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)
Answer:
Explanation: D
Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.
A is wrong because that tells you perimeter
B is wrong because that tells you the midpoint
C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors
D is correct, this perfectly explains the distance formula

7. How does friction affect the kinetic energy of an object?
Answer:
Friction is a resistive force to motion. When two bodies move against each other some of the kinetic energy is converted to heat energy due to friction. This reduces the total kinetic energy in the system. ... Mechanical energy is reduced due to friction and converted to heat.
Explanation:
Kinetic friction does oppose the relative motion of two surfaces. If the one of these surfaces is stationary, then it will tend to slow down the moving object.

If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay:
how many protons will be left in the nucleus?
how many neutrons will be left in the nucleus?
Answer:
Protons = 28
Neutrons = 42
Explanation:
Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2
Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.

Answer:

hope it helps you make me as brainlylistPotential energy will be greatest at the points A and G, and kinetic energy will be greatest at the point D.
• The energy possessed by an object due to its motion is termed as the kinetic energy. On the other hand, the energy stored within an object because of its position relative to some zero position is known as the potential energy of the object.
• Kinetic energy is highest when the velocity is the highest, in the case of pendulum, this takes place at the bottom. In the given case, that is, at point D.
• If kinetic energy is highest at point D, then at the same point potential energy will be the lowest.
• Therefore, potential energy would be highest at its highest point on each of the side of its motion where it remains stationary for some time, that is, at point G and A.
Thus, kinetic energy would be highest at point D, and potential energy would be highest at the points A and G.

A wave is traveling from one medium to another.If the wave is partially transmitted an partially reflected from the boundary,what will happen to the amplitude of the reflected wave?
Answer: the answer is C
Explanation:
if you crash your car how could you decrease the damage to you or the car using the concept of impulse
Explanation:
Crumple zones are sections in cars that are designed to crumple up when the car encounters a collision. Crumple zones minimize the effect of the force in an automobile collision in two ways. By crumpling, the car is less likely to rebound upon impact, thus minimizing the momentum change and the impulse.

The way a rock reflects light is called the rock's
A. streak
O B. luster
O C. cleavage
D. specific gravity
The way a rock reflects light is called the luster of the rock. Hence option B is the correct answer.
What is Reflection?When light rays bounce off one surface, transition from one transparent medium to the next, or proceed through a media whose structure is constantly shifting, they change direction.
According to the law of reflection, the angle of the reflected ray when reflecting from a level surface is the same as the angle of the ray. (By practice, all angles in wave propagation are expressed with regards to the normal to the surface, or to the line that is perpendicular to it.
The light beam and the surface normally establish a plane in which the reflected beam is always located. The pictures created by straight and curved mirrors can be understood using the

What is the velocity of the objects position vs time graph
Answer: In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing

Choose one object or instrument. Write a detailed explanation of what happens when a loud and quiet sound is made. Use the words vibration, energy, longitudinal wave, amplitude and particles in your answer.
Answer:
This extra energy causes the string to vibrate more, which helps it move more air particles for a longer time. A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.

What happens to the average kinetic energy of water molecules as water freezes
A. It increases as the water releases energy to its surroundings
B. It increases as the water absorbs energy from its surroundings
C. It decreases as the water releases energy to its surroundings
D It decreases as the water absorbs energy from its surroundings
Answer:
C. It decreases as the water releases energy to its surroundings
Explanation:
The energy that is possessed in the body because of the motion is said to be kinetic energy. When the water freezes, the kinetic energy of the water molecules decreases as the particles stop motion. The energy is released in the surrounding. Freezing takes place when the liquid molecules slow down and lose the kinetic energy to form the solid crystals.
