A spherical drop of water carrying a charge of 41pC has a potential of 570 V at its surface (with V=0 at infinity) (a) The radius of the drop is approximately 5.88 micrometers (μm).

(b) The potential at the surface of the new drop formed by combining two drops of the same charge and radius is approximately 1140 V.

(a) To find the radius of the drop, we can use the formula for the potential of a charged sphere, which is given by V = (k * Q) / r, where V is the potential, k is the electrostatic constant, Q is the charge, and r is the radius of the sphere. Rearranging the formula to solve for the radius, we have r = (k * Q) / V. Plugging in the given values of Q = 41 pC (pico coulombs) and V = 570 V, and using the value of k = 8.99 × 10^9 Nm^2/C^2, we can calculate the radius to be approximately 5.88 μm.

(b) When two drops combine to form a single spherical drop, the total charge remains the same. Therefore, the potential at the surface of the new drop can be calculated using the same formula as before, but with the combined charge. Since each drop has the same charge and radius, the combined charge will be 2 times the original charge. Plugging in Q = 82 pC (2 * 41 pC) and using the given value of V = 570 V, we can calculate the potential at the surface of the new drop to be approximately 1140 V.

Answer:

40%

Explanation:

The efficiency of a system is calculated as the ratio of the useful power output to that of the input power.

Efficiency = useful output/input x 100%

In this case, input power = 5j, useful output = 2j

Efficiency = 2/5 x 100%

                   = 40%

The efficiency of the buzzer is, therefore, 40%.

The result of multiplying a particle's mass by its velocity is the fluctuation in momentum of a ball, which is 30 kg per second. Since momentum has both a magnitude and a direction, it is a vector quantity.

Almost every action that involves motion has momentum. It is an important tenet of physicsFor instance, if a team is moving forward and trying to stop, it will be difficult.

mv - mu, where u = 0 and v = 10 m/s, equals change in momentum.  Note that the ball moved from rest, therefore its initial velocity was zero (u = 0).

Momentum change is equal to mv mu, which is 3*10 - 3*0, or 30.

30 kg/s = change in momentum.

Momentum can be compared to the "power" a moving body has, or the amount of force it can exert on another body. For instance, a baseball that is thrown quickly (high velocity) and has a small bulk (big mass) can have the exact same momentum as a bowling ball that is travelling very slowly (low velocity).

To determine the length of a string fixed at both ends, given its linear mass density, tension, and fundamental frequency, we can use the formula for the fundamental frequency of a vibrating string. By rearranging the formula and solving for the length of the string, we can find the desired length.

The fundamental frequency of a vibrating string is given by the formula f = (1/2L) * sqrt(T/μ), where f is the frequency, L is the length of the string, T is the tension, and μ is the linear mass density.

In this case, we know the fundamental frequency (f = 220 Hz), the tension (T = 20.0 N), and the linear mass density (μ = 1.50 g/m = 0.0015 kg/m).

To find the length of the string, we can rearrange the formula as L = (1/2f) * sqrt(T/μ). Substituting the given values into the formula, we have L = (1/2 * 220 Hz) * sqrt(20.0 N / 0.0015 kg/m).

Simplifying this expression will give us the length of the string.

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The accurately described circuit is option D. In a series circuit, the amount of current passing through each part of the circuit may vary.

In a series circuit, components are connected one after another in a single path, forming a loop. The same current flows through each component in a series circuit, meaning that the current is constant throughout the circuit. This is known as Kirchhoff's current law, which states that the total current entering a junction is equal to the total current leaving the junction.

However, the amount of current passing through each individual component may vary. This is because the components in a series circuit offer different amounts of resistance to the flow of current. According to Ohm's Law, the current in a circuit is determined by the voltage applied and the resistance of the circuit.

Components with higher resistance will restrict the flow of current more, causing a decrease in the amount of current passing through them. Therefore, in a series circuit, the current remains the same at any point in the circuit, but the amount of current passing through each component may vary depending on its resistance. Therefore, the correct answer is option D.

The pulley system to the right will be in static equilibrium at an unknown angle of 90 degrees.

An object must satisfy two requirements of equilibrium in order to maintain static equilibrium. First, there must be no net force acting on the item. Second, there must be no net torque pulling on the object.

The 80 N weight is fastened to a freely rotating pulley in this setup.

As a result, the cable's tension is also 80 N.

The tensions' x components must be balanced against one another:

T1x = T2x

Since T1x = T1 cos(θ) and T2x = 0 (because the cable attached to the wall is vertical), we have:

T1 cos(θ) = 0

Therefore, cos(θ) = 0, which means that θ = 90 degrees.

Answer: 31.80m

Explanation:

Given the following :

Initial Velocity (u) = 1.7m/s

Acceleration (a) = 1.2m/s²

Time (t) = 6seconds

Distance covered during the process:

Using the motion equation; calculate the final velocity (v)

v = u + at

v = 1.7 + (1.2*6)

v = 1.7 + 7.2

v = 8.9m/s

We can then find the distance covered during the process using :

v² = u² + 2aS

Where ; v = final velocity ; u = initial velocity

S = distance and a = acceleration

Hence,

8.9² = 1.7² + (2 × 1.2 × s)

8.9² = 2.89 + (2.4 × s)

79.21 = 2.89 + 2.4s

79.21 - 2.89 = 2.4s

76.32 = 2.4s

s = 76.32 / 2.4

s = 31.8m
