The two key properties of a telescope are its aperture and magnification.

The aperture, which is the diameter of the telescope's main lens or mirror, is important because it determines how much light the telescope can gather. The larger the aperture, the more light the telescope can collect, which allows for clearer and brighter images.

Magnification, on the other hand, determines how much larger an object appears through the telescope compared to the bare eye. While higher magnification can be useful for seeing fine details, it is important to balance this with the telescope's aperture to ensure that images remain bright and clear.

Ultimately, both properties are essential for creating high-quality images and allowing astronomers to study celestial objects in greater detail.

The electric field strength at point (x,y) = (20 mm, 0cm) is 16.76 N/C and the electric field strength at point (x,y) = (0cm, 20 mm) is 16.80 N/C.

The magnitude of the point charge is ± 5. 0 nC and distance between the point charges is 3. 0 mm. Let's first find the electric dipole moment;

p = qd= 5.0 nC × 3.0 mm = 15.0 × 10^−9 C m

The electric field strength at point (20 mm,0cm) is given by;

E= kp/r²

Electric field strength, E1 at point P1 (20 mm, 0 cm) is given by;

The distance of P1 from the charges is;

r1 = √(x₁ - x₂)² + (y₁ - y₂)²= √(20² + 1.5²) = 20.03 mm = 20.03 × 10⁻³ m

Using Coulomb's law;

F = kq₁q₂/r² ; where k = 9 × 10^9 Nm²/C²;

We can find the electric field strength at P1 using the formula:

E1= kp/r1² = (9 × 10^9 Nm²/C²) (15.0 × 10^−9 C m)/(20.03 × 10⁻³ m)²= (9 × 10^9 × 15 × 10^−9)/(20.03 × 10⁻³)²= 16.76 N/C

Now, let's find the electric field strength at point (0cm,20 mm). The electric field strength, E2 at point P2 (0cm, 20 mm) is given by;

The distance of P2 from the charges is;

r2 = √(x₁ - x₂)² + (y₁ - y₂)²= √(20² + 3) = 20.01 mm= 20.01 × 10⁻³ m

Using Coulomb's law;

F = kq₁q₂/r² ; where k = 9 × 10^9 Nm²/C²;

We can find the electric field strength at P2 using the formula;

E2= kp/r2² = (9 × 10^9 Nm²/C²) (15.0 × 10^−9 C m)/(20.01 × 10⁻³ m)²= (9 × 10^9 × 15 × 10^−9)/(20.01 × 10⁻³)²= 16.80 N/C

Therefore, the electric field strength at point (x,y) = (20 mm, 0cm) is E1 = 16.76 N/C. The electric field strength at point (x,y) = (0cm, 20 mm) is E2 = 16.80 N/C.

A typical AC brushless alternator/generating system used on a modern large aircraft usually uses two magnetic fields to make the system work: a rotor magnetic field and a stator magnetic field.

The rotor magnetic field is produced by a set of permanent magnets or an electromagnetic field generated by direct current (DC) fed to the rotor windings, while the stator magnetic field is produced by three-phase alternating current (AC) fed to the stator windings.

The relative motion between the rotor and stator magnetic fields induces an AC voltage in the stator windings, which is rectified and regulated to produce a DC voltage for the aircraft's electrical systems.

The magnitude of the net force on the fully submerged tank at the beginning of a dive (when it is full of air) is -9.488 N

The buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. In this case, the fully submerged scuba tank displaces 15.7 L of seawater, which has a mass of:

m = density x volume = 1025 kg/m^3 x 0.0157 m^3 = 16.1285 kg

Therefore, the buoyant force on the tank is:

F_b = m_fluid x g = 16.1285 kg x 9.81 m/s^2 = 158.425 N

The weight of the fully submerged tank is:

F_g = m_total x g = (13.5 kg + 3.2 kg) x 9.81 m/s^2 = 167.913 N

The net force on the tank is the difference between the buoyant force and the weight of the tank:

F_net = F_b - F_g = 158.425 N - 167.913 N = -9.488 N

The negative sign indicates that the net force is downward, which means that the tank is sinking at the beginning of the dive.

If the following reactions were coupled, glucose + Pi glucose-6-phosphate ΔG°' = 13. 8 kJ/molATP + H2O ADP + Pi ΔG°' = -30. 5 kJ/mol The overall  ΔG° would be -16.7 kJ/mol.

Coupling of reactions refers to the use of an exergonic reaction to drive an endergonic reaction. In other words, the energy released by the exergonic reaction is used to drive the endergonic reaction. The Gibbs free energy change (ΔG) of a coupled reaction can be calculated using the equation:

ΔG°’ = ΔG°’ of reaction 1 + ΔG°’ of reaction 2

Where ΔG°’ is the standard free energy change, which is the change in free energy that occurs when the reactants and products are in their standard states at a specified temperature, pressure, and concentration.

In this case, the first reaction involves the conversion of glucose and inorganic phosphate to glucose-6-phosphate, and has a ΔG°’ of 13.8 kJ/mol. This reaction is endergonic, meaning it requires energy input to proceed. The second reaction involves the hydrolysis of ATP to ADP and inorganic phosphate, and has a ΔG°’ of -30.5 kJ/mol. This reaction is exergonic, meaning it releases energy.

To determine whether these reactions can be coupled, we need to calculate the overall ΔG°’ of the coupled reaction using the equation above:

ΔG°’ = 13.8 kJ/mol + (-30.5 kJ/mol)

ΔG°’ = -16.7 kJ/mol

The overall ΔG°’ of the coupled reaction is negative (-16.7 kJ/mol), indicating that the coupled reaction is exergonic and can proceed spontaneously. This means that the energy released by the hydrolysis of ATP can be used to drive the conversion of glucose and inorganic phosphate to glucose-6-phosphate.

This coupling of reactions is important in biological systems, where energy is often needed to drive endergonic reactions such as biosynthesis. For example, in the human body, the energy released by the hydrolysis of ATP is often used to drive the synthesis of macromolecules such as proteins and nucleic acids. Overall, the coupling of exergonic and endergonic reactions is a fundamental principle in biochemistry and plays a crucial role in many biological processes.

Any object free to rotate about a pivot will come to rest with its center of mass directly below the pivot, provided there are no external torques acting on it. This is known as the principle of rotational equilibrium. The center of mass is the point at which the object can be balanced on a single point, and if it is directly below the pivot, the object will not rotate further. This principle is commonly used in the design and analysis of objects that pivot, such as seesaws, balance scales, and doors.

Rotational equilibrium means that the object's net torque is zero. This occurs when the sum of the torques acting on the object is balanced and there is no rotational acceleration. In other words, the object is in a balanced state where there is no tendency for it to rotate further.

For an object to come to rest in rotational equilibrium, the torques acting on the object must balance each other out. This can occur when the object's weight or gravitational force acts at the center of mass, or when external forces or torques are applied in a way that cancels out the existing torques.

In summary, when an object free to rotate about a pivot comes to rest, it will come to rest in a state of rotational equilibrium where the net torque acting on the object is zero.

Electricity itself doesn't travel through an electric circuit at near the speed of light.

Instead, it's the flow of charged particles called electrons that move through the circuit, typically at a much slower speed.

In a metal wire, for example, electrons move through the wire in a series of small steps, with an average drift velocity of only a few millimeters per second.

However, the electric field that drives the flow of electrons propagates through the circuit at nearly the speed of light.

This is because electric fields are a type of electromagnetic wave, and electromagnetic waves can travel through a vacuum or through a material medium at the speed of light.

In the case of an electric circuit, the electromagnetic wave travels along the wires and creates a flow of electrons, but the wave itself moves at the speed of light.

At a fixed location, the phase changes by 55.04 radians during a time interval of 0.01 s.

First use the formula to find the wavelength of the wave:

wavelength = speed/frequency

Use the fact that the speed of a wave is related to its wavelength and frequency by the formula:

speed = wavelength x frequency

Rearrange this to get:

wavelength = speed/frequency

Now find the speed. Use the fact that the wave has a frequency of 880 Hz to find the wavelength using the formula:

speed = wavelength x frequency

speed = wavelength x 880

Use the given information that the difference in phase between two positions is π/3 radians.

The difference in phase between two positions is related to the difference in distance between those positions by the formula:

phase difference = 2π(distance difference)/wavelength

Rearrange this formula to get:

distance difference = wavelength(phase difference)/(2π)

Now substitute in the values:

distance difference = (speed/frequency)(π/3)/(2π)

Simplifying this expression gives:

distance difference = speed/(6frequency)

Find the speed to answer part (a). Using the earlier equation that relates speed, wavelength, and frequency:

speed = wavelength x frequency

substitute in the frequency and rearrange to get:

wavelength = speed/frequency

wavelength = (speed)/(880 Hz)

Use the given information in part (b) to find how much the phase changes during a time interval of Δt = 0.01 s.

The phase of a traveling wave changes over time according to the formula:

phase change = 2π(frequency)(time interval)

Substituting the given values gives:

phase change = 2π(880 Hz)(0.01 s) = 55.04 radians
