an l-r-c circuit, operating at 60 hz , has an inductor with an inductance of 1.53×10−3h , a capacitance of 1.67×10−2f , and a resistance of 0.329 ω . what is the inductive reactance of this circuit?

A substance's atoms split from one another when it transforms from a liquid to a gas. The distance between atoms widens in a gaseous state as opposed to a liquid state. In a gaseous condition, the atoms are randomly moving. Entropy is growing.

A substance's physical state transitions from its gas phase to its liquid phase through the process of condensation. When water vapor comes into touch with a solid surface, it can also be said to transform into water droplets. The solute and solvent can be removed from their solution with the help of this procedure. The solvent evaporates from the solution when it is heated, and is then separated when it condenses.

Despite the fact that a liquid and a gas are both at the same temperature, a gas has greater thermal energy than a liquid. Consider the fact that the thermal energy of the same substance's liquid molecules is lower than that of its gaseous molecules. As a result of their greater kinetic energy, the gas molecules are "freer" to move more.

Hume suggests that the assumption of objects being permanent can be argued for based on our repeated and consistent experiences.

In other words, through our constant observations of objects remaining unchanged over time, we develop a belief in their permanence.

This assumption is a result of the principle of induction, which states that the future will resemble the past based on our past experiences.

Hume argues that our belief in the permanence of objects is not derived from reason or logic but rather from habit and custom. We have observed objects behaving consistently in the past, and therefore we expect them to behave similarly in the future.

However, according to Hume, this belief is not grounded in any necessary connection between past and future events. It is simply a product of our psychological inclination to infer causality and continuity based on our repeated observations.

Thus, while we may assume objects to be permanent based on our experiences, Hume suggests that this assumption lacks a solid rational foundation.

When the green rubber ball leaves the person's hand (frame 120)

Explanation:

Remember, we are told to answer based on the green rubber ball, which means we are to take note of the moment when the green rubber ball leaves the person's hand (frame 120).

However, if we decide to set the time at the start of the video or when the green rubber ball reaches the top, we would get inaccurate results.

When a ball is thrown upwards at an angle to the horizontal b. the velocity of the ball changes during the flight but acceleration remains constant.

When a ball is thrown upwards at an angle to the horizontal, it experiences two forces: gravity and the force of the throw. Gravity pulls the ball downwards, while the force of the throw pushes the ball upwards and forwards. The net result of these two forces is that the ball follows a curved path, called a parabola.

The velocity of the ball is the rate of change of its position. In other words, it is the speed and direction of the ball. The velocity of the ball changes throughout its flight. When the ball is first thrown, it has a high velocity in the upwards and forwards direction. As the ball rises, its upwards velocity decreases, until it reaches zero at the highest point of its flight. After this, the ball starts to fall, and its downwards velocity increases.

The acceleration of the ball is the rate of change of its velocity. In other words, it is the rate at which the ball's speed and direction change. The acceleration of the ball is constant throughout its flight. This is because the only force acting on the ball is gravity, and gravity always accelerates objects downwards at the same rate.

Thus the correct answer is b. The velocity of the ball changes during its flight.

Answer:

B. A large current forms, drops to zero, then a smaller current forms in the opposite direction

Explanation:

The results of Lionel observation about electromagnetic induction is as follows:

In the first step, a large current will form because of the fast or quick movement of the magnet into the right end of a solenoid that generates a  induces emf.

In the second step, the magnet was in rest position for 3 s so the current drops to zero because according to Faraday's law, no voltage will be generated if the magnet held stationary and no voltage means no current.

In the third step, smaller current forms in the opposite direction as the magnet is slowly moving away from the solenoid generating a smaller voltage.

Hence, the correct answer is "B."

Answer:

Explanation:

Definitely NOT! Mass is unchanging, wherever you go. On the moon you will have the same mass as you will on the earth. Mass is just a measure of the matter that makes up a body. Weight, however, is dependent upon the pull of gravity which is different on earth than it is on the the moon, for example.

Mass doesn't change with proximity whereas weight can.

Answer: No

Explanation: The terms'mass' and 'weight' are frequently used interchangeably, yet they have distinct meanings. Your mass remains constant regardless of where you are in the universe; nevertheless, your weight varies. The mass of anything is a measure of how much power is required to change its course.

A) The Temperature Coefficient of Resistance (TCR) of the sensor element is 0.00385 °C⁻¹.

B) The sensitivity of the sensor at 25 °C is 3.85 Ω/°C.

C) The transfer function of the sensor, RT = R25(1 + T/100), shows a linear relationship between the change in temperature and the change in resistance. As the temperature increases, the resistance of the sensor increases proportionally. Similarly, as the temperature decreases, the resistance decreases proportionally. The plot of the transfer function for the range [-60, 150] °C would be a straight line with a positive slope, indicating a direct relationship between temperature and resistance.

D) If the temperature changed from 25 to 26 °C, the absolute change in resistance observed can be calculated using the transfer function. RT1 = R25(1 + T1/100) and RT2 = R25(1 + T2/100), where T1 and T2 are the initial and final temperatures, respectively. Plugging in the values, RT1 = 1000 Ω(1 + 25/100) = 1250 Ω and RT2 = 1000 Ω(1 + 26/100) = 1260 Ω. The absolute change in resistance would be RT2 - RT1 = 1260 Ω - 1250 Ω = 10 Ω.

A) The Temperature Coefficient of Resistance (TCR) represents the change in resistance per degree Celsius change in temperature. It is calculated by dividing the change in resistance by the change in temperature. In this case, since the transfer function is given as RT = R25(1 + T/100), we can see that the TCR is 0.00385 °C⁻¹, indicating that for every degree Celsius increase in temperature, the resistance increases by 0.00385 times the reference resistance.

B) The sensitivity of the sensor at 25 °C refers to the change in resistance per degree Celsius change in temperature at the reference temperature. Since R25 is given as 1000 Ω, the sensitivity is equal to the TCR, which is 0.00385 Ω/°C.

C) The transfer function RT = R25(1 + T/100) describes the relationship between the temperature and resistance of the sensor. The plot of this function for the temperature range [-60, 150] °C would be a straight line with a positive slope. This indicates that as the temperature increases, the resistance also increases, and as the temperature decreases, the resistance decreases. The slope of the line represents the TCR or sensitivity of the sensor, which is constant throughout the range.

D) To determine the absolute change in resistance when the temperature changes from 25 to 26 °C, we can use the transfer function. By substituting the values into the function, we find that the resistance changes from 1250 Ω to 1260 Ω, resulting in an absolute change of 10 Ω.

Answer:

B

Explanation:

The new gravitational force between the two heavenly bodies is six times the original gravitational force.

The gravitational force between two heavenly bodies can be calculated using Newton's law of universal gravitation;

F1 = G × (m1 × m2) / r²...eq (1)

gravitational constant = G

mass 1 = m1

mass 2 = m2

radius = r

distance between them constant,

we can calculate the new gravitational force F2 using the formula:

F2 = G × (m1 × m2) / r²; where

gravitational constant = G

mass 1 = 2m1 (doubled)

mass 2 = 3m2 (tripled)

radius = r

on substitution,

F2 = G × (2m1 × 3m2) / r²

= G × (6m1m2) / r²

= 6 × G × (m1m2) / r²

⇒ (G × (m1 × m2) / r² = F1 )...from eq. (1)

= 6 × F1

⇒ F2 = 6F1

Therefore, the new gravitational force will be six times the original gravitational force when one mass is doubled and the other mass is tripled.

If one of the masses in a gravitational system is doubled and the other mass is tripled while keeping the distance between the bodies constant, then the new gravitational force will increase by a multiple of:

6 (2 x 3 = 6)

We know from Newton's Law of Gravitation that the gravitational force between two objects is:

F = G * (m1 * m2) / r^2

Where:

F = Gravitational force

G = Universal gravitational constant

m1 = Mass of first object

m2 = Mass of second object

r = Distance between the objects

Since the distance (r) between the two bodies remains constant in the given scenario, it drops out when calculating the change in force.

We are only concerned with how the change in masses affects the force.

Based on the equation, we can see that the gravitational force is directly proportional to the product of the two masses (m1 * m2).

If one mass doubles and the other mass triples, their product will increase by a multiple of 2 x 3 = 6.

Therefore, the new gravitational force between the two heavenly bodies will increase by a factor of 6, compared to the original gravitational force when only one mass was doubled and the other mass tripled, while keeping the distance constant between them.
