digital. Copies were made of each recording to sell. The table below
compares the copies made using analog and digital signals.
Answers
Answer:the answer is A and B
Explanation:
Option A and B are two reasons why digital signals are more dependable than analog signals for copying sound recordings. Options A and B are correct.
What is digital signal?A digital signal is one in which data is represented as a series of discrete numbers.
To reduce the influence of noise in communication, a digital signal is utilized. When compared to analog signals, digital signals convey more information per unit time.
The digital signal has a higher quality throughout long distance transmission. The use of bandwidth is reduced when digital signals are sent.
The two reasons the digital signal is a more reliable way to copy sound recordings than the analog signal are;
A. The digital signal uses a limited number of values.
B. The digital signal is less affected by noise.
Hence,options A and B are correct.

A tuna traveling at 12 m/s starts to decelerate steadily. It comes to a complete stop in 10 seconds. What is its acceleration?
Answers
Answer:
a = -1.2 m/s^2
Explanation:
Vi = 12 m/s
Vf = 0 m/s
t = 10 s
Plug those values into the following equation:
Vf = Vi + at
0 = 12 + 10a
---> a = -1.2 m/s^2

mirror is also shown.
The man looks at the image of his feet.
a. Complete the ray diagram to show how the man is able to see the
image of his feet in the mirror.
b. What is the purpose of the normal line in the diagram?
c. State which angle does x represent.
d. What's the type and direction of the image formed by the mirror?
Answers
Answer:
a) ray horizontal and ray leaves his feet
b) The normal line respect to which the angles are measured,
c) The angle x is the reflected angle
d) virtual image, right image
Explanation:
a) To complete the rays, you must draw a horizontal ray at the height of the man's head, this ray touches the mirror perpendicularly, therefore it bounces in the same direction.
The other ray leaves his feet and touches the mirror at one point, it is reflected with the same angle, by the law of reflection and reaches the eyes of man, the brain creates an extension of this ray and at the point of the floor creates the image point.
b) The normal line is a line perpendicular to the surface with respect to which the angles are measured,
c) The angle x is the reflected angle, which is equal to the incident angle according to the law of reflection
d) The image is formed by the prolongation of the rays of light, therefore it is a virtual image and as it has the same direction of the man it is a right image

The work done in lifting a brick of mass 2kg through a height of 5m above the ground will be
(A)2.5J
(B)10J
(C)50J
(D)100J
Answers
Answer:
D. 100 J
Explanation:
Given
Mass (m) = 2 kg
Height (h) = 5 m
Acceleration due to gravity (g) = 10 m/s²
Now
Work done(W)
= m * g * h
= 2 * 10 * 5
= 100 Joule
Hope it will help :)❤
The work done in uplifting a brick having a mass of 2kg along with a height of 5m above ground level would be:
D). 100 J
Given that,
Mass of the brick [tex]= 2Kg[/tex]
Height of the brick [tex]= 5m[/tex]
As we know,
Work Done (W) [tex]= mgh[/tex]
where
m = Mass
g = Acceleration due to gravity
h = height
A.T.Q.
By substituting the given values, we get;
[tex]Work Done (W)[/tex] [tex]= 2[/tex] × [tex]10[/tex] × [tex]5[/tex] (taking [tex]g = 10 m/s^2[/tex])
[tex]= 100 J[/tex]
Thus, the work done is 100 J and hence, option D is the correct answer.

Define A Gamma Ray .....---_---__☘️
Answers
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
