a system is a collection of particles or interacting parts that is regarded as a unique physical entity for the purposes of study.
What is a physical entity?It is an entity that has a physical existence. An entity is something that exists in itself, real or potential, concrete or abstract, physical or not. It does not have to be of material existence. In particular, legal abstractions and fictions are generally considered entities. Also, in general, an entity is not considered animate. The word entitative is the adjective form of the nominal entity. Something entity is considered for itself. In philosophy, ontology consists in recognizing entities. The words ontic and entity derive from the present participles of ancient Greek and Latin, respectively, meaning being.

a certain freely falling object, released from rest, requires 1.45 s to travel the last 27.0 m before it hits the ground.
By using uniform motion, the speed before hitting the ground is 23.00 m/s.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
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 and s is displacement.
From the question above, we know that
vo = 0 m/s
t = 1.45 s
y = 27 m
g = 9.8 m/s²
By using the second equation, we can calculate the speed before hit the ground.
vt² = vo² + 2a . s
vt² = 0² + 2g . 27
vt² = 2 . 9.8 . 27
vt² = 529.2

The average speed = (2 × the length of the path to the university in km) / (7.7 h)
The exact length of the path to the university is not given in the question but it is not unanswerable, therefore, consider that distance to be L measured in kilometres.If the distance is given in meters you need to convert it to kilometres as the question asks in that unit.The definition of the average speed is the key to the answer to this question which is given by
average speed = total distance covered [tex]\div[/tex] total time elapsed
So, the total distance covered is the addition of the distance of the trip to the university from home and the distance covered the way back home which is twice the distance to the university from home.And the total time taken to cover that distance is measured as 7.7 h and it can be thought of as follows as well.time to go - time to come = total time taken = 7.7 h

A sine wave has a rms value of 208 v, the peak value is 294.15v.
What is rms?The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or square of the function that defines the continuous waveform. In physics, RMS current value can also be defined as the "value of the direct current that dissipates same power in a resistor".
Physical scientists often use the term root mean square as a synonym for standard deviation when it can be assumed input signal has zero mean, that is, referring to the square root of mean squared deviation of a signal from a given baseline or fit. This is useful for the electrical engineers in calculating "AC only" RMS of a signal. Standard deviation being the RMS of a signal's variation about the mean, rather than about 0, DC component is removed (that is, RMS(signal) = std e v (signal) if the mean signal is 0).
Mean power, or root mean square (RMS) power handling, refers to how much continuous power speaker can handle. The peak power handling value refers to the maximum power level that speaker is capable of utilizing in short bursts.

As an airplane accelerates in level flight, what parameter must the pilot adjust to keep level and balance (lift = weight)?
As an airplane accelerates in level flight, pilot must adjust to keep level and balance at the angle of attack.
What is the type of lift in reference to airplane?When the air flows through the wingspan of an airplane, it generates a pressure difference between the upper and lower portions of wings. Due to this pressure difference, an upward force is generated that acts in upwards direction known as the aerodynamics lift.
In this case:
At the equilibrium condition, the upward lift generated by the airplane is equal to the weight of airplane. The lift generated depends upon area of the wind span, density, and velocity of the air; these values can not be changed by the pilot. But by changing the angle of attack parameter, the desired lift can be produced, and angle of attack can be changed easily by the pilot.
Therefore as an airplane accelerates in level flight, the parameter the pilot must adjust to keep it level and balance the lift to the weight is angle of attack.

A glass rod that has been charged to 14.0 nc touches a metal sphere. afterward, the rod's charge is 7.0 nc . what kind of charged particle was transferred between the rod and the sphere?
The charged particles that transferred between the glass rod and the metal sphere were electrons.
The rod has lost some of the charges it had earlier as the remaining count of charges is less than the previous one.Before analysing the type of the charge it is worthy to know about the conductive properties of both the materials.Glass is insulative while metal is conductive. Conductive materials in the sense have free electrons in abundance compared to insulative materials that conduct electricity within them. Glass, in comparison, does not conduct charges dynamically but rather keeps them stationary where those were originated. Electrons are more dynamic than protons.In this case, the metal sphere is neutral at the beginning that contained equal amounts of negative(electrons) and positive(protons) within it. Once the rod is taken close and eventually touched the sphere the more dynamic electrons flow into the rod nullifying the charges the rod had earlier.Therefore, it can be concluded that the type of charges the rod had were positive ones(protons) and the charges moved between them were electrons from the sphere to the rod.Otherway around is impossible.Finally, the sphere contains an amount of positive 7.0 nC charge while the rod contains the remainder of 7.0 nC on the parts which did not touch the sphere.

Answer:
the answer is source of sound
The power increases by a factor of [tex]10^3,[/tex]or 1000. In other words, the final power level is 1000 times greater than the initial power level.
What is a decibel scale?The decibel (dB) scale is a logarithmic scale used to express the ratio of two power levels. The formula to calculate the ratio of two power levels in decibels is:
Ratio in dB = [tex]10 * log10 (P2/P1)[/tex]
where P1 and P2 are the two power levels being compared.
To find the factor by which the power increases, we can rearrange this formula to solve for the ratio of the two power levels:
P2/P1 = 10^(dB/10)
In this case, the power level increases from 20 dB to 50 dB, so the ratio in dB is:
Ratio in dB = 50 dB - 20 dB = 30 dB
Substituting this value into the formula, we get:
[tex]P2/P1 = 10^(30/10) = 10^3[/tex]
