Explanation:

In graph 4, the resultant vector has an upward slope, in graph 5 the slope is slightly upward whereas, in graph 6, the resultant vector goes parallel to temperature.

In graph 4 from point 1 to point 2, the temperature increased but there is no increase in pressure at point 2 there is a sudden increase in pressure with no increase in temperature.

In graph 5 from point 1 to point 2, the pressure dropped suddenly with no change in temperature than from point 2 to point 3 the change in pressure and temperature is uniform and from point 3 to 4, there is no change in pressure but sudden decrease in temperature occurs.

In graph 6 from point 1 to 2, no change in temperature occurs but sudden change in pressure then from point 2 to 3  more change in pressure but also some change in temperature so the slope goes upwards than from point 3 to 4 no change in pressure but kept increasing then from point 4 to 5 both temperature and pressure dropped.

So we can conclude that graph 4 has upward movement, graph 5 has a slightly moved upward and graph 6 has a parallel line.

FCAT review question

The momentum during the collision is conserved. Hence, the total initial momentum is equal to the total final momentum. Therefore, the initial velocity of the car with a mass of 3250 Kg was, 2.05 m/s.

Momentum of a body is the product of its mass and velocity. Momentum is a vector quantity having both magnitude and direction.

The momentum during a collision is conserved. Thus,the sum of initial momentum of the colliding  bodies is equal to the final momentum of the combined mass.

Given that, mass of car 1 = 2150 Kg

velocity = 10 m/s

Momentum = mass × velocity.

= 10 m/s × 2150 Kg = 21500 kg m/s.

Mass of car 2 = 3250 kg

the combined mass = 3250  + 2150 = 5400 Kg

final velocity = 5.22 m/s

final velocity = 5400 Kg × 5.22 = 28188 kg m/s .

momentum of car 1 + momentum of car 2 = 281888 kg m/s

21500 kg m/s + (3400 Kg × V) = 281888 kg m/s

v = 2.05 m/s.

Therefore, the initial velocity of the car with a mass of 3250 Kg is 2.05 kg m/s.

The initial  velocity is zero. and the acceleration is constant. Thus the average velocity of the boat is 4.12 m/s. The boat will cover a distance of 19.6 m within 4.77 s.

Acceleration is a physical quantity that, measures the rate of change in velocity. It is a vector quantity thus having both magnitude and direction. It can be defines as the ratio of change in velocity to the change in time.

If the acceleration is constant, then the magnitude of velocity is constant.

Given initial velocity = 0 since the boat was in rest.

then the average speed of the boat = 4.12 m/s

Δt = 4.77 seconds.

The distance covered within this time can be determined using the equation as follows:

s = speed × time.

s =  4.12 m/s × 4.77 s = 19.6 m

Therefore, the boat will travel up to 19.6 m within 4.77 seconds.

The tension in the wires is greater when they are not vertical (option B).

When the wires are vertical, they are only supporting the weight of the painting, which is acting straight down due to gravity.

However, when the wires are at an angle, they are not only supporting the weight of the painting but also providing a force to counteract the component of the weight that is acting perpendicular to the direction of the wires.

This means that the wires are under more tension when they are at an angle than when they are vertical.

In other words, the tension in the wires is directly proportional to the angle between the wires and the vertical direction.

The greater the angle, the greater the tension in the wires. This is why it is important to use an appropriate angle when hanging heavy objects with wires, to ensure that the wires are under enough tension to support the weight without breaking.

Answer:

yes it is true

Explanation:

The force exerted on the electron has the magnitude of  \(8\times10^{-14} N\). The force on an electric charge q in an electric field E is given by the formula F = qE.

Here, the charge on the electron is \(q = 1.60\times 10^{-19} C\), and the electric field is \(E = 5\times10^5 N/C\).

the electron's Magnitude of force is given by :\(F = (1.60\times10^{-19} C)(5\times10^5 N/C) = 8\times10^{-14} N\)

This force is directed opposite to the direction of the electric field because the electron has a negative charge. Since all other forces acting on the electron are negligible in comparison to the electric field force, we can assume that the electron moves with a constant acceleration given by F = ma. The acceleration of the electron can be determined by using the formula a = F/m.

Substituting the values, we get

\(a = \frac{8\times10^{-14} N)}{(9.11\times10^{-31} kg)} = 8.78\times10^{16} m/s^2.\)

The acceleration of the car at the top of the hill is 6.6 m/s²

acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

The third kinematic equation is applied to determine the car's tangential acceleration, as illustrated below: v2 = u2 + 2as, where a represents the vehicle's acceleration.

2x50 a = -5.25 m/s²;

2as = v² - u² a

= v²-u² / 2s

a = 102 - 252

At the summit of the hill, the car's centripetal acceleration is given as ac=v²/r

ac=10²/25

ac=4 m/s2.

At the summit of the hill, the car's net acceleration is computed as follows: a net = a2 + ac

The strongest proponents of the human unconscious mind's role in personality are Sigmund Freud and his followers.

Freud believed that the human psyche is divided into three parts: the conscious, the preconscious, and the unconscious. He posited that the unconscious mind is the most powerful and influential part of the psyche, containing all of the individual's repressed memories, desires, and instincts that have been banished from conscious awareness.

According to Freud's psychoanalytic theory, personality is shaped by the interplay of three fundamental structures: the id, the ego, and the superego. The id represents the unconscious and is driven by primitive instincts, such as the pleasure principle. The superego represents the conscious and is driven by moral and ethical considerations. The ego represents the conscious and preconscious and is responsible for mediating the conflicting demands of the id and the superego.

Freud and his followers believed that unconscious conflicts and unresolved issues from childhood have a significant impact on adult behavior, and that these unconscious factors must be brought to light and resolved in order for a person to achieve psychological health and well-being. While some aspects of Freud's theories have been controversial and are not supported by modern research, his ideas about the role of the unconscious in shaping personality have had a lasting impact on the field of psychology.

To protect wiring before it gets to the fuse box, a circuit breaker is installed.

A circuit breaker is a device that automatically switches off a circuit's flow of electricity when it detects a fault. This action helps to prevent fires, equipment damage, and electrical hazards. It is a device that functions as a safety guard for electrical circuits to keep the devices from becoming overloaded or shorted.

Circuit breakers safeguard the electrical equipment by breaking the flow of current when the current exceeds the permitted level, or when the current exceeds the rated level of a wire in a circuit. The fuses are a different type of protection that is installed between the device being protected and the circuit's power source.

Fuses are designed to stop the flow of electrical power when the current exceeds the fuse's safe capacity. In most cases, a fuse will blow before the electrical current reaches the device being protected, protecting it from damage.
