Answer:

Resistor A

Explanation:

Resistors A, B and C are connected in parallel to a battery of voltage represented by V.

Since they are in parallel, the same voltage, V, passes across the three of them.

And from Ohm's law, the voltage (V) through a resistor is the product of the current (I) flowing through it and the resistance (R) of the resistor. i.e

V = I x R

=> I = \(\frac{V}{R}\)

Therefore, assuming the values of the resistances of resistors A, B and C are A, B and C respectively,

(i) the current, \(I_{A}\) through A is

\(I_{A}\) = \(\frac{V}{A}\)

(ii) the current, \(I_{B}\) through B is

\(I_{B}\) = \(\frac{V}{B}\)

(iii) the current, \(I_{C}\) through C is

\(I_{C}\) = \(\frac{V}{C}\)

From the foregoing, it can be deduced that the current is inversely proportional to the resistance. Therefore, the higher the resistance, the lower the current. Consequential of this, the resistor that carries the highest current is the one with the smallest resistance, which is A

Resistor A

Given:

Resistors A, B and C are connected in parallel to a battery of voltage represented by V.

Since they are in parallel, the same voltage, V, passes across the three of them.

Ohm's law:

It states that voltage (V) through a resistor is the product of the current (I) flowing through it and the resistance (R) of the resistor. i.e.

V = I x R

⇒ I = V/R

Therefore, assuming the values of the resistances of resistors A, B and C are A, B and C respectively,

(i) the current,  through A is

\(I_A=\frac{V}{A}\)  

(ii) the current,  through B is

\(I_B=\frac{V}{B}\)

(iii) the current,  through C is

\(I_C=\frac{V}{C}\)  

From the Ohm's law we can say that the current is inversely proportional to the resistance.

Therefore, higher the resistance, the lower is the current.

It is given that resistance of A being the smallest, thus is will carries the highest current.

The object with least mass would have the least amount of kinetic-energy if they were traveling at the same speed.

Equation of kinetic energy is  \(KE = (1/2) mv^2\)

m is the mass of the object and v is velocity.

From the equation of kinetic energy we can see two factors which kinetic energy is depends upon. First one is mass of the moving object. Second one is the velocity of the object.

Kinetic energy is directly depending on the mass of the object. That means if mass is higher, then kinetic energy also higher.

Likewise kinetic energy directly depends upon the square of the velocity of the object. So if velocity of A is twice than B, then the kinetic energy of A will be 4 times than of B.

In the question it is stated that objects are traveling at the same speed. If the speed is same that is if velocity is same, then the only factor that affects the kinetic energy will be mass of the moving objects.

A electric motor is a device that uses electricity and magnetisim to create motion

The uncertainty in the position of the electron is estimated to be within a range determined by the uncertainty in its speed.

According to the Heisenberg uncertainty principle, there is a fundamental limit to the precision with which we can simultaneously measure certain pairs of physical properties, such as position and momentum. In this case, the uncertainty in the speed of the electron leads to an uncertainty in its position.

To estimate the uncertainty in the electron's position, we can use the principle that , where Δx represents the uncertainty in position, Δp represents the uncertainty in momentum, and ħ is the reduced Planck's constant. Since momentum is defined as the product of mass and velocity (p = mv), we can express the uncertainty in momentum as Δp = mΔv, where m is the mass of the electron and Δv is the uncertainty in its speed.

Given the range of speeds for the electron (between \(6.0×10^6 m/s\) and \(6.6×10^6 m/s)\), we can calculate the difference in momentum (Δp) by subtracting the lower speed from the upper speed. Then, using the uncertainty principle, we can solve for the uncertainty in position (Δx).

By applying the uncertainty principle and considering the range of speeds for the electron, we can estimate the uncertainty in its position. The calculation involves determining the difference in momentum resulting from the range of speeds and using this value to find the uncertainty in position. The exact numerical value of the uncertainty will depend on the specific mass of the electron and the given range of speeds.

The relative speeds of the two objects at the bottom of the incline will be zero.

In segment 1, the object is released from rest at the top of an inclined plane. As it rolls down the incline, the potential energy is converted into both kinetic energy and rotational energy.

Assuming no slipping occurs, the object's linear velocity increases while its angular velocity remains constant.

During segment 2, where no frictional force is exerted, there are no external forces acting on the object. As a result, there is no change in the object's kinetic energy or angular velocity. Therefore, the object's linear velocity remains constant.

At the bottom of the incline, both objects will have the same linear velocity. Since they are identical objects, the relative speed between them will be zero.

The energy required to convert 1.70 g of ice originally at -12°C into steam at 105°C is approximately 6162.95 Joules.

To calculate this energy, we need to consider the different energy changes involved in each phase transition. First, we calculate the energy required to heat the ice from -12°C to its melting point at 0°C using the specific heat capacity of ice. Then, we calculate the energy required to melt the ice at 0°C using the heat of fusion for ice. Next, we determine the energy needed to heat the resulting water from 0°C to 100°C using the specific heat capacity of water. Finally, we calculate the energy required to convert the water at 100°C into steam at 105°C using the heat of vaporization for water. Adding up all these energy changes, we find that the total energy required is approximately 6162.95 Joules. This calculation takes into account the various temperature changes and phase transitions that the substance undergoes. It highlights the significant amount of energy needed to convert ice to steam, involving both the heating of the substance and the energy required to change its state.

So the parametric equation for the line through the point p(-2, 8, 5) and parallel to the vector v is:

x = -2 + t * vx

y = 8 + t * vy

z = 5 + t * vz

The vector equation for a line can be represented as:

p = p0 + t * d

where p0 is a point on the line, t is a scalar parameter, and d is the direction vector of the line. To find the vector equation for the line through the point p(-2, 8, 5) and parallel to the vector v, we need to find the direction vector d and the point p0.

Since the line is parallel to the vector v, the direction vector d will be equal to v. The point p0 can be found by using the point p(-2, 8, 5):

p0 = p - t * d

Plugging in the values for p, d, and t = 0:

p0 = (-2, 8, 5) - 0 * (v) = (-2, 8, 5)

So the vector equation for the line through the point p(-2, 8, 5) and parallel to the vector v is:

p = (-2, 8, 5) + t * (v)

The parametric equation for a line in 3D space can be represented as:

Yes, there can be a non-zero electric field at a point in space where no charged object is present. No, there cannot be an electric field equal to zero at a point where a charged object is present.

An electric field is defined as the force experienced per unit charge at a point in space. Even if there is no charged object present, an electric field can be present due to the presence of other charges in the surrounding area. For example, if there are charges present on a nearby conductor, the electric field can extend into the surrounding space.

On the other hand, it is not possible for an electric field to be equal to zero at a point where a charged object is present. The electric field is a measure of the force exerted on a test charge placed at that point, and a charged object exerts an electric force on other charges. Therefore, an electric field must be present at any point where a charged object is present.

The electric field can be zero at a certain point in space if there are no charges around that point or if the charges around that point balance each other out to create a net zero electric field.

Sometimes no. such as in other types of waves like electromagnetic waves, the medium does not physically move with the wave.

The medium in which a wave travels can move with the wave under certain circumstances, but it is not always the case. The movement of the medium depends on the type of wave and the nature of the medium itself. In mechanical waves, such as sound waves or water waves, the medium particles do indeed move as the wave propagates through them. For example, in a water wave, the water molecules move in a circular or elliptical motion as the wave passes through the water. Electromagnetic waves, including light waves, can travel through vacuum, which has no physical medium. In this case, the wave consists of oscillating electric and magnetic fields that propagate through space without the need for a medium to physically move. Therefore, whether the medium moves with the wave or not depends on the specific characteristics of the wave and the medium it is traveling through.
