Most of the symptoms of physical dependence on tobacco pass in a matter of weeks to a few months after quitting smoking.

Most of the symptoms of physical dependence on tobacco pass in a matter of weeks to a few months after quitting smoking.

Physical dependence on tobacco is primarily caused by the addictive substance nicotine present in tobacco products. When someone smokes or uses tobacco regularly, their body becomes accustomed to nicotine and develops a tolerance, leading to withdrawal symptoms when they try to quit.

Withdrawal symptoms associated with nicotine dependence can include cravings for tobacco, irritability, anxiety, difficulty concentrating, increased appetite, restlessness, and sleep disturbances. However, these symptoms are typically temporary and gradually diminish over time.

Within the first few weeks of quitting smoking, the intensity and frequency of withdrawal symptoms tend to reduce significantly. After several months, most individuals experience a significant reduction or complete resolution of physical dependence symptoms.

It's important to note that the duration and severity of withdrawal symptoms can vary among individuals, and additional support, such as counseling or nicotine replacement therapy, can help manage the process of quitting and reduce the impact of withdrawal symptoms.

Cesar and Ming observed a change in the state of the water from a solid to a liquid.

In the initial observation, when they mentioned that the water molecules were moving in place, it indicates a solid state where the water molecules are tightly packed and vibrating about fixed positions.However, when they observed that the molecules were moving around each other, it indicates a liquid state. In the liquid state, the water molecules have enough energy to overcome the attractive forces between them, allowing them to move more freely and flow past one another.Therefore, the change observed by Cesar and Ming indicates a transition from the solid state to the liquid state of water.

The expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by E = Y * e * ln(L) * A

The work done to stretch the wire can be calculated by integrating the force applied over the displacement. In this case, the force applied is the tension (T) in the wire, and the displacement is the change in length (ΔL) from the original length (L) to the stretched length (L + ΔL).

The tension in the wire is given by Hooke's law, which states that the tension is proportional to the extension of the wire:

T = Y * (ΔL / L)

where Y is the Young's modulus of the material of the wire.

Now, let's calculate the work done to stretch the wire:

dW = T * dL

Integrating this expression from L to L + ΔL:

W = ∫ T * dL = ∫ Y * (ΔL / L) * dL

W = Y * ΔL * ∫ (dL / L)

W = Y * ΔL * ln(L) + C

Here, C is the constant of integration. Since the energy stored in the wire is zero when it is unstretched (ΔL = 0), we can set C = 0.

Finally, the expression for the energy stored in the wire (E) is:

E = W = Y * ΔL * ln(L)

or, if we substitute the cross-sectional area (A) and strain (e) of the wire, where e = ΔL / L:

E = Y * e * ln(L) * A

Thus, the expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by:

E = Y * e * ln(L) * A

Answer:

time taken t = 6.00 seconds

the time taken to cover half a round is 6.00 seconds

Explanation:

Given;

Speed of ant v = 11 m/s

radius of Circle r = 21 m

Circumference of a circle

c = 2πr

Half a turn d = c/2 = 2πr/2 = πr

Time taken to cover distance d( half a turn);

time = distance/speed = d/v = πr/v

Substituting the values;

time =(π×21)/11 = 5.997585975035 seconds

time taken t = 6.00 seconds

It takes 6 seconds for the ant to cover half a round.

Speed is the time rate of change of distance. It is given by:

Speed = distance / time

Since the radius of the circle is 21 m:

Distance covered for one round = 2π * radius = 2π(21) = 132 m

Distance covered for half round = 132 m/2 = 66 meter

Time taken to cover half a round:

Speed = distance/time

11 = 66/time

Time = 6 seconds

Force is directly proportional to the mass of the body. The small insects weight so small thus the force exerted by the insect will be smaller. Thus the force exerted by the car is greater.

Force is an external agent acts on a body to change it from the state of rest or motion. Various kinds of forces include magnetic force, frictional force, nuclear force, gravitational force etc.

In physics, force is the product of mass and the acceleration. Thus force has the expression F = ma. Therefore, the force exerted from a massive body is greater than the force exerted from a lighter body.

The car is very large in comparison to the insect and it weighs a lot where, the weight of the insect and the force exerted by it is negligible. Hence, the force exerted by the massive body that is car is larger than that by the small insect.

A passenger rushes down onto a subway platform and finds her train already departing. she stops and watches the cars go by. each car is 8.60 m long. the first moves past her in 2.10 s and the second in 1.83 s. The constant acceleration of the train is 236.16 m/s².

To calculate the constant acceleration of the train, we can use the following equation:

acceleration = 2 * (change in distance) / (change in time)²

Given:

Length of each car = 8.60 m

Time taken for the first car to pass = 2.10 s

Time taken for the second car to pass = 1.83 s

Step 1: Calculate the change in distance between the two cars:

change in distance = length of each car = 8.60 m

Step 2: Calculate the change in time between the two cars:

change in time = time taken for the second car to pass - time taken for the first car to pass

change in time = 1.83 s - 2.10 s = -0.27 s (The negative sign indicates that the second car passed before the first car)

Step 3: Calculate the acceleration:

acceleration = 2 * (change in distance) / (change in time)²

acceleration = 2 * 8.60 m / (-0.27 s)²

acceleration = 2 * 8.60 m / (0.27 s)²

acceleration = 2 * 8.60 m / 0.0729 s²

acceleration = 17.2 m / 0.0729 s²

acceleration = 236.16 m/s²

Therefore, the constant acceleration of the train is approximately 236.16 m/s².

Explanation:

Among the four students sitting at a train crossing and listening to the train's horn, one of them can best explain the changing sounds in terms of the Doppler Effect.

The Doppler Effect refers to the change in frequency and pitch of a sound wave as the source of the sound moves relative to an observer. In this scenario, as the train approaches the crossing, the sound waves emitted by its horn are compressed, resulting in a higher frequency and pitch. This increase in frequency causes the sound to appear louder to the observer.

As the train continues past the crossing and moves away, the sound waves stretch, leading to a lower frequency and pitch. Consequently, the sound appears softer to the listener. Among the four students, the one who understands this phenomenon and can explain the changing sounds in terms of the Doppler Effect is best equipped to interpret the observed auditory changes accurately.

Answer:

it is chemical energy

Explanation:

that is the energy used by our body, so it is the one that we will loose. and the energy that we gain is also chemical energy

Answer:

Explanation:

The answer is A. First of all, due to the First Law of Thermodynamics, energy cannot be created or destroyed, it only changes form. That being said, it is impossible for the PE and the KE to both increase or decrease at the same time. The second one starts decreasing, the other starts increasing at the exact same rate. PE exists or is at its highest when an object has the potential to fall to a point lower than it is, and it is at this point where Kinetic energy is the lowest. If this block is kicked UP a ramp, which is odd but there you have it, the potential energy increases as it gets higher off the ground. Because of gravity, and assuming that once the block is kicked, the foot that kicked it is no longer important to it (meaning it's not being pushed up, it's just kicked once and that's it) and it will slow down very quickly. KE exists where there is a great amount of velocity.

The answer is A.

Taking into account the definition of molarity, the concentration of a solution that contains 70 g of H₂SO₄ in 0,28 dm³ of solution is 2.5510 \(\frac{moles}{L}\).

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

\(Molarity=\frac{number of moles}{volume}\)

Molarity is expressed in units \(\frac{moles}{L}\).

In this case, you have:

Replacing in the definition of molarity:

\(Molarity=\frac{0.7143 moles}{0.28 L}\)

Solving:

Molarity= 2.5510 \(\frac{moles}{L}\)

The graph showing F as a function of y shows that D, the cube will oscillate between y=0.05 m and y=0.09 m.

From the graph, the force exerted on the cube increases linearly as the cube is displaced upwards from its equilibrium position at y = 0.07 m. When the cube is displaced to y = 0.05 m, the net force is upward and greater than the weight of the cube. This causes the cube to accelerate upward.

As the cube moves upward, the force exerted by the water decreases until it is equal to the weight of the cube at y = 0.07 m. At this point, the net force on the cube is zero and the cube momentarily comes to rest.
