The tension developed in the cable is 245.25 N.
What is tension Force?In physics, tension is defined as the pulling force transmitted axially by a string, cable, chain, or other similar object, or by either end of a rod, truss member, or other comparable three-dimensional object.
Tension can also be thought of as the action-reaction pair of forces acting at each end of the aforementioned elements. The polar opposite of compression might be tension.
CalculationOnly two forces act on the traffic light: the tension T of the cable (upward) and the weight of the traffic light (downward).
The weight is mg = 25 x 9.81 = 245.25 N
If the traffic light is at equilibrium, the resultant of the two forces must be equal to zero (Newton's second law):
T - mg = 0
Therefore, the tension of the cable is.
T = mg = 245.25 N

a. 30 n.
b. 300 n.
c. 3000 n.
d. more than 3000 n.
3000 N of friction exists between the bear and the tree.
How does friction force work?
Friction is the force that prevents two solid objects from rolling or sliding over one another. Even though frictional forces, such as the traction required to walk without slipping, may be advantageous, they can also be a significant hindrance to motion.Between solid surfaces, there are three basic types of friction:
RollingSliding.Static. They are graded from strongest to weakest. Fluid friction happens when liquids or gasses are mixed together.Explanation:
The bear goes down at a constant speed, thus there is no acceleration. The forces add up to zero. As a result, upward friction and downward weight result in zero
i.e.,
F-mg=0
F = mg
F = (300 kg)/10 [tex]m/s^{2}[/tex] (gravitational acceleration)

Branches of physics and their meanings
Answer:
Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches.
MECHANICS :
Mechanics is the branch of physics that deals with the motion of an object without or with the reference of force. Mechanics can be further divided into two branches, namely quantum mechanics and classical mechanics. Quantum mechanics deals with the behaviour of the smallest particles like neutrons, protons, and electrons, while classical mechanics is the branch that deals with laws of motion of forces and physical objects.
OPTICS :
This branch of physics deals with the behaviour, propagation, and properties of light. Optics can be simply described as the study of the behaviour of infrared light, visible light, and ultraviolet.
THERMODYNAMICS:
Thermodynamics deals with the study of heat and its relation with work and energy. Thermodynamics also deals with the transmission of heat energy by means of convection, conduction, and radiation.
ELECTROMAGNETISM:
Electromagnetism deals with the study of electromagnetic force like electric fields, light, magnetic fields, etc. There are two aspects of electromagnetism which are “electricity” and “magnetism”.
RELATIVITY:
This branch of physics deals with the theorem that was formulated by Albert Einstein. The theory of relativity states that space and time are relative and all the motion must be relative to a frame of reference.
ACOUSTICS :
Acoustics deals with the study of sound and its transmission, production, and effects. Acoustics mainly involves the mechanical waves in gases, liquids, and solids, which include vibration, sound, ultrasound, and infrasound.
A boy sledding down a hill accelerates at 1.25 m/s2. if he started from rest, in what distance would he reach a speed of 5.30 m/s?
By uniform motion, the distance traveled is 11.24 meters.
We need to know about the uniform motion to solve this problem. The uniform motion is the motion of an object which has acceleration applied. It can be determined as
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time interval and s is displacement.
From the question above, we know that:
a = 1.25 m/s²
vo = 0 m/s
vt = 5.3 m/s
By using the second equation, we can calculate the distance
vt² = vo² + 2a . s
5.3² = 0² + 2 . 1.25 . s
2.5s = 28.09
s = 11.24 m

explain why ???? and ???? can have magnitudes higher than the magnitude of the input source voltage when circuit 2 is at (or close to) resonance.
The reason why voltage across the inductor and capacitor can have higher magnitudes than that of input source voltage is because of electrical energy's oscillation between magnetic and electric field.
When current passes through an inductor a magnetic field is produced and the collapsing magnetic field produced by the inductor charges the capacitor. This process repeats itself causing the electrical energy to oscillate between magnetic and electric field. Because of this oscillation, at resonance, voltage across the inductor and capacitor can be greater than the input voltage.
For a RLC circuit,
[tex]V_{s}[/tex] = [tex]\sqrt[]{V_{R}^{2} + (V_{L} - V_{C})^{2} }[/tex]

Identify the element(s) and standard(s) of critical thinking with corresponding essential question(s) relative to your perception of the ethical dilemma.
An ethical dilemma describes a conflict between two morally correct courses of action.
Being able to reason effectively and logically about what to believe or do is known as critical thinking. It comprises the capacity for independent and thoughtful thought. These are some examples of what someone with critical thinking abilities can do:
Recognize the logical relationships between concepts.Determine, create, and assess arguments.Find logical errors and common contradictions.Approach issues methodically.Determine the applicability and significance of concepts.Consider how one's own values and opinions are justified.The ability to think clearly and rationally is crucial whatever we choose to undertake. It should go without saying that critical thinking is crucial if you work in the fields of education, research, business, law, or management.

an open electrical circuit as a result of a failed circuit breaker is considered to be what type of failure system?
Answer:
Fail-close
Explanation:
A failed open switch is a switching device (be it mechanical, relay, semiconductor) that has lost it's switching capabilities (it's defective) and the switched contacts are now constantly open (disconnected) regardless of the control signal to the switch.
Similarly a failed closed switch is the same just with the contacts connected through.
A race car is moving at 40.0 m/s around a circular racetrack of radius 265 m. calculate the period of the motion.
The race car that is moving at 40.0 m/s around a circular racetrack of radius 265 m has a period of motion of 41.63 s
To solve this tangential velocity problem the formula and the procedure we will use is:
v = (2 * π * r) / T
Where:
v = tangential velocityπ = mathematical constantr = radiusT = periodInformation about the problem:
v = 40.0 m/sπ = 3.1416r = 265 mT=?Applying the tangential velocity formula and isolating the period, we get:
v = (2 * π * r)/ T
T = (2 * π * r)/ v
T = (2 * 3.1416* 265 m) / 40.0 m/s
T = (1665.04 m) / 40.0 m/s
T = 41.63 s

In the photoelectric effect, a beam of light impinges on metal, and it is observed that electrons are ejected from the metal in greater numbers as the intensity of light increases.
In physics, the photoelectric effect refers to a phenomenon in which the emission of charged particles takes place from a material or substance after absorbing electromagnetic radiation.
When light hits the surface of the material then electrons are released known as photoelectrons.
This phenomenon better explains the quantum nature of electrons and light.
Moreover, the study of the dual nature of wave particles has further expanded the scope, investigation, and understanding of the matter.
