Heat is thermal energy that is transferred from a hotter body to a cooler body.

Heat is the transfer of kinetic energy from one means or object to another, or from an energy origin to a medium or object. Such energy transfer can occur in three ways: radiation, instruction, and convection. Heat is the exchange of "thermal” energy due to a temperature difference. examine an isolated system made up of two subsystems initially at two different temperatures.

Heat is a form of energy that built the substance hot. In winter, it is our usual experience that we feel cold inside the house, and heat if we come out in front of sun rays, then we experience warm.

So we can conclude that Heat is also called thermal energy.

Y-component of the electrostatic force on q3 is 9.36 x 10^-5 N.

Electrostatic force is an attractive as well as repulsive force caused by electric charge particles

As F = k * q1 * q2 / r^2

k is Coulomb constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are  magnitudes of the charges, and r is separation distance between the charges.

F1_y = k * q1 * q3 / r1^2 * sin(θ1)

r1 is separation distance between q1 and q3 and θ1 is angle between r1 and the positive Y-axis.

F2_y = k * q2 * q3 / r2^2 * sin(θ2)

r2 is separation distance between q2 and q3 and θ2 is angle between r2 and the positive Y-axis.

r1 = sqrt((7.0 m)^2 + (0 m)^2) = 7.0 m

θ1 = tan^(-1)(0 / 7.0) = 0 rad

r2 = sqrt((7.0 m)^2 + (6.0 m)^2) = sqrt(65.0) m = 8.06 m

θ2 = tan^(-1)(6.0 / 7.0) = 0.98 rad

F1_y = k * (7.00x10^0 µC) * (6.0000x10^0 µC) / (7.0 m)^2 * sin(0) = 0 N

F2_y = k * (-9.000x10^0 µC) * (6.0000x10^0 µC) / (8.06 m)^2 * sin(0.98 rad) = 9.36 x 10^-5 N

F_y = F1_y + F2_y = 9.36 x 10^-5 N

So, the Y-component of the electrostatic force on q3 is 9.36 x 10^-5 N.

The components of vector D in ordered pair notation are (3, -3).

What is components of vector ?

A vector is a mathematical object made up of components. Each component is a number that describes a certain aspect of the vector. For example, a vector in two-dimensional space has two components, one representing its horizontal position and one representing its vertical position.The components of a vector can be used to calculate the magnitude, or length, of the vector. This is done by taking the square root of the sum of the squares of the components.The components of a vector also determine its direction. This is calculated by taking the arctangent of the ratio of the vertical component to the horizontal component.Finally, the components of a vector can be used to calculate its lag, which is the amount of time it takes for the vector to reach its destination. This is calculated by dividing the length of the vector by its speed.

This means that the x component is 3 and the y component is -3. Both of these components should be expressed to the nearest integer.

We say that momentum is conserved, we mean that the total momentum of a system remains constant.

This means that in any interaction or collision, the total amount of momentum before and after the collision is the same. This is due to the law of conservation of momentum, which states that the total momentum of a closed system (meaning that no external forces are acting on it) is constant. This means that the total momentum before and after an interaction must be the same, as the momentum of the system cannot be changed unless an external force acts on the system. Whether an elastic or non-elastic collision occurs, momentum is always conserved. Kinetic energy, however, is not conserved in a non-elastic collision; instead, it is transformed into heat energy, potential energy, etc.

Property of an electric field that may be thought of as the number of electric lines of force that intersect a given area is called electric flux .

The electric flux through each face of the cube can be calculated using:

Φ = EA

Φ is electric flux, E is electric field strength at the surface, and A is area of the surface

E = kQ/r^2

where k is the Coulomb constant, Q is the charge of the point, and r is the distance from the point to the surface. For a cube of side length a, r is equal to a/2.

Φ = kQA/r^2 = kQA/(a/2)^2 = 2kQA/a^2

The acceleration of the particle is given as the derivative of velocity with respect to time.

The derivative of velocity is acceleration. Acceleration is the rate of change of velocity over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration is typically measured in meters per second squared (m/s2). Acceleration can be positive, negative, or zero. Positive acceleration means that the velocity is increasing, negative acceleration means that the velocity is decreasing, and zero acceleration means that the velocity is constant. Acceleration can be caused by forces such as gravity, friction, and propulsion. For example, when an object is dropped, the force of gravity causes it to accelerate until it reaches a terminal velocity.

From the graph, it can be seen that the velocity of the particle increases with time when t is less than 1s, and it decreases with time when t is more than 1s. This implies that the acceleration of the particle is positive when t is less than 1s and is negative when t is more than 1s. Hence, the variation of acceleration of the particle with time is that it is positive when t is less than 1s and it is negative when t is more than 1s.

Answer:

A and D

Explanation:

A positively charged balloon expands as it is blown up, increasing in size from the initial to final diameters shown. The electric fields at points 1,2, and 3 will increase.

As the balloon expands, the amount of electric charge on its surface increases proportionally. This increase in charge results in an increase in electric fields at each of the three points. Point 1 is closer to the balloon than points 2 and 3, so the increase in the electric field will be greater at point 1 than at points 2 and 3.  

At point 1, the electric field will increase as the balloon expands because the amount of electric charge on the balloon increases. The electric field at point 1 is proportional to the amount of charge on the balloon. Points 2 and 3, however, are farther away from the balloon and will experience a smaller increase in the electric field.  When the balloon is inflated, the electric field lines become more concentrated and the electric field becomes stronger.

All three points will experience an increase in the electric field as the balloon expands, with point 1 experiencing the greatest increase. This is due to the fact that point 1 is closest to the balloon and therefore experiences the greatest increase in the electric field as the amount of charge on the balloon increases.

A good leaving group favors SN1 reactions.

A good leaving group is defined as a species that is readily displaced from a substrate by a nucleophile. A good leaving group should have a low bond dissociation energy and be a stable species. In SN1 reactions, the rate-determining step involves the formation of a carbocation intermediate, which is why a good leaving group is favored in these reactions. The carbocation intermediate is stabilized by a good leaving group, which makes the reaction more favorable and increases the reaction rate.

In contrast, SN2 reactions are characterized by a direct attack of the nucleophile on the substrate without an intermediate step, and the rate of the reaction is determined by the concentration of both the substrate and the nucleophile. A good leaving group is less important in SN2 reactions since the reaction does not involve an intermediate species.

As n is not an integer, so there will be no constructive interference between the speakers, if speaker A is moved by minimum distance. So, the answer is 0.

Interference is a phenomenon in which two waves combine by adding  displacement together at every single point in space and time and to form a resultant wave of greater, lower, or same amplitude.

Wavelength of a 500 Hz sound wave is the speed of sound (about 343 m/s) divided by the frequency of the sound, which is 343/500 m = 0.686 m. Therefore, minimum distance you can move speaker A to achieve constructive interference along x-axis is 0.686/2 m = 0.343 m.

Given, distance between the speakers is 6 m. Constructive interference will occur when path difference between two waves is equal to integer multiple of the wavelength. To achieve constructive interference, distance between the speakers + the distance moved by speaker A should be equal to n × wavelength, where n is integer.  

So, 6 + 0.343 = n × 0.686
