The repelling thrust between the two plastic spheres is [tex]2.83x10^-13 N[/tex].

The force of repulsion between two plastic spheres can be calculated using Coulomb's Law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

The formula for Coulomb's Law is:

Where F is the force of repulsion, k is Coulomb's constant [tex](9x10^9 Nm^2/C^2)[/tex], q¹ and q² are the charges on the plastic spheres, and r is the distance between them.

Given that each sphere has a deficit of [tex]1.2x10^8[/tex] electrons, we can calculate the charge on each sphere using the formula q = n*e, where n is the number of electrons and e is the charge of an electron [tex](1.6x10^-19 C)[/tex].

[tex]q¹ = q² = (1.2x10^8)*(1.6x10^-19) = 1.92x10^-11 C[/tex]

Plugging in the values into the formula for Coulomb's Law, we get:

[tex]F = (9x10^9)*(1.92x10^-11)*(1.92x10^-11)/(1.1)^2F = 2.83x10^-13 N[/tex]

Therefore, the force of repulsion between the two plastic spheres is [tex]2.83x10^-13 N[/tex].

Answer:

0.11m

Explanation:

The speed of sound at 21°C is approximately 343 m/s.

To calculate the wavelength for a frequency of 3 kHz, we can use the formula:

wavelength = speed of sound / frequency

Plugging in the values we have:

wavelength = 343 m/s / 3000 Hz = 0.1143 meters

Rounding to two decimal places, we get a wavelength of 0.11 meters or 0.11 m.

Light energy with very low amplitude would be perceived dim.

To the human sight, such low amplitude light energy would appear weak. This is because of the  wave's amplitude, which in the case of light relates to the light's intensity or brightness and t will measure the size of its oscillations.

In other words, as a light wave's amplitude falls, it loses energy and becomes brighter to the eye. This is true because light with a specific range of amplitude and moderate intensity is best perceptible to the human eye. When there is insufficient light that falls outside of this spectrum, it is seen as being faint or invisible.

The uncertainty given as "0.2 cm" in the report represents the precision of the measurement. This type of uncertainty is known as random or statistical uncertainty

Random uncertainty arises as a result of measurement technique limitations, such as the limitations of the measuring instrument or the experimenter's ability to read the instrument. Random uncertainty can be reduced by improving measurement technique or taking more measurements to improve result precision.

The reported value of "23.6 cm" is the best estimate of the true value of the quantity being measured in this case, and the uncertainty of "0.2 cm" indicates the range of values within which the true value is likely to lie. It means that if the measurement were repeated multiple times, the values obtained with a certain level of confidence (typically 95% confidence interval) would be expected to fall within the range of 23.4 cm to 23.8 cm.

The excess charge on the conducting sphere is 3.98×10⁻⁶ C.

Electric potential is a scalar quantity that describes the electrical potential energy per unit charge of a charged object or system. It is also known as voltage and is measured in volts (V).

Electric potential is defined as the work done per unit charge in moving a small positive test charge from an infinite distance to a point in an electric field. It is a measure of the electric potential energy that a unit charge would have if it were placed at that point in the field.

The excess charge on a conducting sphere can be calculated using the formula:

Q = 4πε0R V

Where Q is the excess charge on the sphere, R is the radius of the sphere, V is the potential of the sphere, and ε0 is the permittivity of free space.

Placing the given values into the equation, we get

Q = 4πε0R V

Q = 4π(8.85×10⁻¹² F/m) (0.15m) (1500V)

The conversion from meters per second (m/s) to Mach is dependent on the speed of sound, which varies with temperature and altitude.

Mach is a unit of speed that is based on the speed of sound in a given medium, usually air. It is defined as the ratio of the speed of an object to the speed of sound in the same medium. The speed of sound, in turn, is affected by temperature and altitude, since the density and compressibility of the medium change with these factors.

Therefore, the conversion factor between m/s and Mach is not a fixed value, but rather depends on the specific conditions of the medium in which the object is traveling. A common approximation for the speed of sound at sea level and 15 degrees Celsius is 340 m/s, which corresponds to Mach 1.

When two identical parallel plate capacitors are given the same charge Q, after which they are disconnected from the battery. after C2 has been charged and disconnected, it is filled with a dielectric. Comparing the voltages of two capacitors will result to

The voltage V of a capacitor is given by the formula

V = Q/C,

where

Q is the charge on the capacitor and

C is the capacitance of the capacitor.

Since the two capacitors are identical and have the same charge Q, their voltages V1 and V2 before disconnection from the battery would be equal

V1 = V2.

After C2 has been charged and disconnected, and a dielectric is inserted, the capacitance of C2 increases, which in turn reduces the voltage across it. This is because the charge on the capacitor remains the same, but the capacitance increases, leading to a decrease in the voltage.

Therefore, the voltage V2 across C2 decreases, and the voltage V1 across C1 remains the same. Hence, the correct option is (a) V1 > V2.

The firemen should adjust the angle of elevation of the hose to 41.1 degrees in order to hit the building 45.0 m away in 3.00 s.

We can use the equations of motion to solve this problem. We know that the initial velocity of the water stream is 25.0 m/s and that it moves in projectile motion. We need to find the angle of elevation α that will allow the water to reach a building 45.0 m away in 3.00 s.

Let's define the x-axis to be horizontal and the y-axis to be vertical. The initial velocity of the water stream can be broken down into its x and y components:

vx = v cosα = 25.0 cosα

vy = v sinα = 25.0 sinα

where v is the magnitude of the initial velocity.

Using the equation of motion for the x-direction, we can find the time it takes for the water to reach the building:

x = vx t

45.0 = 25.0 cosα t

t = 45.0 / (25.0 cosα)

Using the equation of motion for the y-direction, we can find the angle of elevation:

y = vy t - 1/2 g t^2

0 = 25.0 sinα (45.0 / (25.0 cosα)) - 1/2 (9.81) (45.0 / (25.0 cosα))^2

0 = 45.0 tanα - 1/2 (9.81) (45.0 / 25.0)^2

tanα = (1/2) (9.81) (45.0 / 25.0)^2 / 45.0

α = tan^-1((1/2) (9.81) (45.0 / 25.0)^2 / 45.0) = 41.1 degrees
