Why do some people in the music industry still prefer analog music storage? Analog introduces background noise to the original recording. Analog devices record the music in its original form. It takes less time to record the music through analog devices. The equipment is lighter and less bulky for recording analog signals.
The people in the music industry still prefer analog music storage. Because analog devices record the music in its original form.
What is analog device storage?There are advantages to both digital and analog music. Even today, music connoisseurs debate the subject incessantly.
Understanding both recording methods can help you appreciate music more by providing you with a better understanding of playback depth. Analog and digital songs have different effects on playback,
But both can identify the various aspects of a song. In honor of music as a whole, we're diving into both and bringing out the best of each.
Hence people in the music industry still prefer analog music storage. Because analog devices record the music in its original form.

A) It is able to move on its own.
B) Sunlight is used to make its own food.
C) Water is not needed for survival.
D) It does not need sunlight to survive.
Answer:
A
Explanation:
Because plants cant move and animals can.
The characteristic which describes an organism of kingdom Animalia is able to move on its own when compared to the plants kingdom. Thus, the correct option is A.
What are the characteristics of Animalia Kingdom?Animals are the multicellular, eukaryotic organisms in the biological kingdom Animalia. Animals are the organisms which consume organic material, breathe oxygen gas, are able to move on their own, can reproduce sexually and produce organisms which contain genetic information which is recombination of both the parents, and these organisms go through an ontogenetic stage in which their body consists of a hollow sphere of the cells, the blastula, during the embryonic development of organisms.
Organisms belong to Animal kingdom show some characteristics which are not found in the organisms which belong to the plant kingdom including movement. Animals can move on their own while plants cannot.

Using the velocity versus time graph, what was the average acceleration of the object during segment B?
a) 0 m/s/s
b)20 ms/s
c) 10 m/s/s
d) 5 m/s/s
Answer:
the answer is B 20 ms/s
Explanation:
N/A
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.
Average acceleration- Acceleration is defined as the rate of change of acceleration. Average acceleration for an interval can be defined as the rate of change of velocity for that interval per time.
Let [tex]\Delta v[/tex] be the change in velocity and [tex]\Delta t[/tex] be the change in time in a given time interval. Then average acceleration is,
[tex]a= \dfrac{\Delta v}{\Delta t}[/tex]
At segment B, It starts at 4.5 seconds and ends at 10 seconds. The total time interval for this segment is 5.5 seconds.Therefore,
[tex]\Delta t=5.5[/tex]
Now the change in velocity for segment B. In segment B the velocity does not change at any point and keeps the value of 20 m/sec at the time interval.
According to the definition of the average acceleration when an object is changing its velocity (whether by a constant amount or a varying amount) then it is an accelerating object. And an object with a constant velocity is not accelerating.
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.

A 2.0 Kg box is being pulled up a ramp with a force of 25.0 Newtons. The ramp has an incline of 30 degrees. If the coefficient of friction is 0.752, find the acceleration of the block up the ramp. You may round your answer to the nearest tenth where necessary!!!
Answer:
The acceleration of the block is 1.21 m/s².
Explanation:
Given that,
Mass = 2.0 kg
Force = 25.0 n
Angle = 30°
Coefficient of friction = 0.752
We need to calculate the acceleration of the block
Using balance equation
[tex]F-(mg\sin\theta+\mu mg\cos\theta)=ma[/tex]
Put the value into the formula
[tex]25-(2.0\times9.8\sin30+0.752\times2.0\times9.8\cos30)=2.0a[/tex]
[tex]a=\dfrac{25-(2.0\times9.8\sin30+0.752\times2.0\times9.8\cos30)}{2.0}[/tex]
[tex]a=1.21\ m/s^{2}[/tex]
Hence, The acceleration of the block is 1.21 m/s².

The resistance of the thermometer at the given temperature is 15.58 ohms.
Resistance of the thermometer
The resistance of the thermometer can be determined by applying method of interpolation as shown below;
[tex]\frac{R_\theta - R_0}{R_{100} - R_0} = \frac{\theta -0}{100 - 0}[/tex]
where;
Rθ is the resistance of the thermometer at 27⁰CR100 is the resistance at steam temperatureR0 is the ice temperature[tex]\\\\\frac{R_\theta - 14.5}{18.5 - 14.5} = \frac{27}{100} \\\\\frac{R_\theta - 14.5}{4} = \frac{27}{100}\\\\100R_\theta - 1450 = 108\\\\100R_\theta = 1558\\\\R_\theta = 15.58 \ ohms[/tex]

what do you mean by electric wind?
Explanation:
The electric field is normal to any conductor charged surface, then any negatively charged sharp end will concentrate the electrons in order to achieve that (being rejected by the others on main body), that also implies a huge voltage drop nearby the edge, meaning high electric field in the direction aimed by the sharp end, that field becomes strong enough (when charged by electrostatic machines) to propel electrons out causing air movement in that direction (a flame will bend because of that wind).
Ion wind, ionic wind, coronal wind or electric wind is the airflow induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative to ground. Ion wind is an electrohydrodynamic phenomenon

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?
Answer:
1.17427...kg
Explanation:
Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.
p=mv, where p is momentum, m is mass, and v is velocity
28.3=24.1(m)
divide both sides by 24.1
you get 1.174273859
Answer:
[tex]\boxed {\tt 1.17427386 \ kilograms}[/tex]
Explanation:
The formula for momentum is:
[tex]p=mv[/tex]
From this formula, we know that mass can be found by dividing the momentum by the velocity.
[tex]\frac{p}{v}=m[/tex]
The momentum is 28.3 kg m/s and the velocity is 24.1 m/s
[tex]p=28.3 \ kg \ m/s \\v=24.1 \ m/s[/tex]
[tex]\frac{28.3 \ kg \ m/s }{24.1 \ m/s} =m[/tex]
Divide. The meters per second or "m/s" will cancel each other out.
[tex]\frac{28.3 \ kg}{24.1} =m[/tex]
[tex]1.17427386 \ kg=m[/tex]
The mass of the object is 1.17427386 kilograms.
