Thomas Edison invented the first incandescent light bulb and, at one point, had a monopoly on the electrical power delivery. Correct option is 3.
Thomas Edison was an American inventor and businessman who is best known for his development of the incandescent light bulb. He began working on the light bulb in 1878 and by 1879, he had developed a bulb that could burn for several hours. Edison went on to improve the design of the bulb and also developed a system for delivering electrical power to homes and businesses, which he called the Edison Electric Light Company.
At its height, the Edison Electric Light Company held a monopoly on the electrical power delivery industry, which allowed Edison to control the distribution of electrical power to homes and businesses. This monopoly lasted for several years until the arrival of competitors, such as George Westinghouse, who developed an alternative system for delivering electrical power.

under what condition may an aircraft operate from a satellite airport within class c airspace?
In a Class C airspace area, it is illegal to take off or land an aircraft at a satellite airport unless you follow the FAA's arrival and departure traffic patterns.
After takeoff, the pilot must speak with the Class C tower as soon as is reasonably possible. As soon as practically possible after taking off, the pilot must establish and maintain two-way radio contacts with the ATC facility in charge of the Class C airspace area if taking off from a satellite airport without an operational control tower. Before entering Class C airspace, pilots are required to establish two-way radio communications. The pilot may enter Class C airspace if the controller replies to a radio call with "(a/c call sign) standby." This signals that radio communications have been established.

how would you compare the deflections of the compass needle in 2 cases what inference can you make based on the observation?
The comparison of deflections in two cases can provide valuable information about the nature and intensity of the magnetic field, which can be used to identify magnetic sources and their characteristics.
The deflection of a compass needle refers to the angle between the direction of the magnetic field and the plane of the compass. The comparison of deflections in two cases can provide valuable insights into the nature and intensity of the magnetic field.
In case 1, if the deflection of the compass needle is small, it indicates that the magnetic field is weak or the field lines are aligned in a direction that is perpendicular to the plane of the compass. In contrast, if the deflection in case 2 is larger, it suggests that the magnetic field is stronger or the field lines are oriented in a direction that is more parallel to the plane of the compass.
Based on this observation, one can make inferences about the presence and characteristics of magnetic sources in the vicinity of the compass. For example, the presence of a large magnetic object like an electromagnet or an iron bar can cause a large deflection in the compass needle, indicating the strong magnetic field. On the other hand, if the deflection is small, it could indicate that the magnetic sources are weak or far away.

why is the mass per repeating unit measured
The atomic masses of the atoms in the repeat unit are simply added together to form the repeat unit's molar mass, or MR. Just the product nMR makes up the chain's molecular mass.
Other than monodisperse polymers, chains of various lengths typically create a molar mass dispersion. A repeat unit, also known as a repeating unit (or mer) in polymer chemistry, is a component of a polymer whose repetition would result in the completion of the polymer chain (aside from the end-groups) by connecting the repeat units consecutively along the chain, much like beads on a necklace. A mer is another name for a repetition unit (or mer unit). This is where the definition of the word "polymer," which is "many mers," comes from.

A particle of mass 4kg initially moving with a velocity of 2m/s collides elastically with a particle of mass 6kg initially moving with a velocity of -4m/s. Then the final velocity of the 4kg mass is -26/5 m/s.
Since the collision is an elastic collision, so there is no loss in kinetic energy. The value of e is 1. Taking the right side as positive and the left side to be negative as the sign convention. Initially the speed of the 4kg mass of the block =2m/s (left to right). The speed of the 6kg block =4m/s (right to left). Let the speed of the masses after a collision to be v₁ and v₂ respectively (left to right both). According to the law of Conservation of momentum, P (initial)= P (final), (4×2)-(6×4) = (4×v1) + (6×v₂),( 2×v₁)+(3×v₂)=-8 _____(eq i).
Now, e=1, so, the velocity of separation after collision/ velocity of approach before the collision. (v₂-v₁)/(4+2) =1 , v₂-v₁ =6, 2×v₂-2×v₁= 12 ______(eq ii). Now from equations (i) and (ii), we have 5×v₂=4, v₂=⅘ m/s. Since the value of v₂ is positive so it means that it moves from left to right. Putting the value of v₂ in eq (ii), we get, v₁=-26/5 m/s.Since the value of v₁ is negative so it moves from right to left.
Hence velocity of 4 kg mass after a collision is -26/5 m/s.

The electrostatic force on Q3 by Q1 is -1.99 N and the force from Q2 is -36.2 × 10⁹ N.. Then the net electric force acting on A is 5.8 × 10⁻⁵ N.
What is Coulomb's law ?According to Coulomb's law of force, the electrostatic force between two charges separated by a distance of r is given as follows:
Fc = Ke q1 q2 /r²
where Ke = 8.9 × 10⁹ Nm²/C²
Given the charge of Q1 = -1.21 ×10⁻⁶ C
charge of Q3 = 148 ×10⁻⁶ C
distance r = 0.447 + 0.447 =0.894 m
then Fc = 8.9 × 10⁹ Nm²/C² (-1.21 ×10⁻⁶ C ) (148 ×10⁻⁶C)/(0. 894 m)² = -1.99 N
Similarly, the force on A by the charge C is calculated as follows:
distance to C = 0.447 m
charge of Q2 = -55 H C = -5500 C
Then Fc = 8.9 × 10⁹ Nm²/C² (-5500 C ) (148 ×10⁻⁶C)/(0.447 m)² = - 36.2 × 10⁹ N
The net electric force acting on Q3 = - 36.2× 10⁹ N + -1.99 N = -38.9 × 10⁹ N.

How does Coulomb's law relate to test charges?
You need the test charge so it doesn't affect the answer.
Coulomb's law is a fundamental principle in electrostatics that describes the interaction between charged objects. This relationship can be described mathematically as: F=k(q1q2)/d^2, where k is a constant of proportionality, q1 and q2 are the magnitudes of the charges, and d is the distance between the charges.
It states that the force between two point charges is proportional to the magnitude of each charge and inversely proportional to the square of the distance between them.
Test charges are used to determine the magnitude and direction of the force acting on a charged object. They are chosen to be small enough that their presence does not significantly alter the original charges, so that Coulomb's law can be accurately applied to the system. By carefully measuring the force acting on the test charges, the magnitude of the original charges can be determined. This is known as the method of test charges and is an important tool in understanding the behavior of charged objects and their interactions with each other.
