The charge enclosed by a Gaussian sphere of radius r, where 0 < r < r, is q. This is because the charge enclosed by a Gaussian surface only depends on the total charge inside the surface, and not on the shape or size of the surface.

In this case, the conducting sphere of radius r is the same as the Gaussian sphere of radius r, so all of the charge q is enclosed by the Gaussian sphere. As the radius of the Gaussian sphere decreases to zero, the charge enclosed by the sphere also decreases to zero, since there is no charge inside the sphere

For a pair of objects, the center of mass is located option (D) along the line between the two objects, closer to the more massive object.

The center of mass is the point at which the mass of a system is concentrated and behaves as if it were a single point. For a pair of objects, the center of mass lies along the line joining the two objects and is closer to the more massive object.

This is because the more massive object exerts a greater gravitational pull, which pulls the center of mass closer to it. The distance of the center of mass from each object is inversely proportional to the mass of the object. Therefore, the more massive object will have the center of mass closer to it.

Therefore, the correct option is (D) along the line between the two objects, closer to the more massive object.

Yes, a capacitor can be used as a high-pass filter. A high-pass filter is a type of electronic circuit that allows high-frequency signals to pass through while blocking or attenuating low-frequency signals.

In a high-pass filter, the capacitor is connected in series with the input signal and a resistor is connected in parallel to the output. The capacitor acts as a barrier to low-frequency signals, allowing only high-frequency signals to pass through to the output. The resistor is used to limit the output signal amplitude and to control the cutoff frequency of the filter.

The cutoff frequency of a high-pass filter is determined by the values of the capacitor and resistor in the circuit. As the cutoff frequency increases, the filter becomes more effective at blocking low-frequency signals and allowing only high-frequency signals to pass through.

Capacitors are commonly used in high-pass filters in a variety of applications, such as in audio equipment to remove low-frequency noise and in signal processing to extract high-frequency components of a signal.

True, instantaneous velocity can be positive, negative, or zero.

Instantaneous velocity is the velocity of an object at a specific moment in time. It can be positive if the object is moving in a positive direction, negative if the object is moving in a negative direction, or zero if the object is not moving at all

Velocity is a measure of how fast an object is moving and in what direction. Instantaneous velocity, as the name suggests, refers to the velocity of an object at a specific instant in time. It is calculated by finding the derivative of the object's displacement with respect to time.

When an object is moving in a positive direction, its instantaneous velocity will be positive. For example, if a car is moving forward on a straight road, its velocity is positive. Similarly, when an object is moving in a negative direction, its instantaneous velocity will be negative. For example, if the same car is moving backward on the same road, its velocity is negative.

The absolute refractory period is a period of time after a neuron fires an action potential during which it is unable to fire another action potential, no matter how strong the incoming stimulus be.

This is caused by the opening and closing of ion channels in the neuron's cell membrane. During an action potential, the neuron's membrane potential rapidly depolarizes, meaning it becomes more positive, due to the influx of positively charged ions such as sodium. This depolarization activates voltage-gated ion channels that allow more positively charged ions to flow into the cell, which in turn causes the membrane potential to further depolarize.

However, during this depolarization phase, there is a brief period where voltage-gated potassium channels also open, allowing positively charged potassium ions to flow out of the cell. This outflow of positively charged potassium ions helps to repolarize the membrane potential, bringing it back towards its resting state.

After the potassium channels close, there is a brief period during which the membrane potential is hyperpolarized, meaning it becomes even more negative than its resting state. During this time, the neuron is in its absolute refractory period and is unable to fire another action potential, because the voltage-gated ion channels are closed and unable to respond to incoming stimuli.

The height of the building is 42.4 meters.

Let's call the height of the building "h". We can use the following kinematic equations to solve for "h":

For the stone that is dropped from the top of the building:

h = (1/2)gt² (Equation 1)

For the stone that is thrown upwards from the ground:

y = vt - (1/2)gt² (Equation 2)

where;

We know that the two stones meet at exactly 5s after their release. This means that the distance travelled by the stone thrown upwards from the ground is equal to the height of the building, i.e.,

y = h

We can substitute this equation into Equation 2 and rearrange it to solve for "t":

h = vt - (1/2)gt²

h = 20t - (1/2)gt²

t = (2h/g - 20)/(-1) (Equation 3)

Now we can substitute Equation 3 into Equation 1 and solve for "h":

h = (1/2)g((2h/g - 20)/(-1))²

h = (1/2)g(2h/g - 20)²

h = (1/2)g(4h²/g² - 80h/g + 400)

Simplifying this equation by multiplying everything by 2g and moving all the terms to one side, we get:

4h² - 160h - 400 = 0

Solving this quadratic equation using the quadratic formula, we get:

h = (160 ± sqrt(160² + 4(4)(400))) / (2(4))

h = (160 ± sqrt(32,000)) / 8

We can ignore the negative solution, so:

h = (160 + 178.88) / 8
