Answer:
Sound quality depends on a lot of factors, and it is impossible to definitively state that either analog or digital is fundamentally better. These days, many records are made using playback of a digital file, so vinyl preference cannot be attributed solely to the differences in the way the sound wave is reproduced.
Explanation:
Answer:
The acceleration is 4, 8 m/s2
Explanation:
We calculate the acceleration, with the data of mass and force, through the formula:
F= m x a ---> a= F/m
a= 435 N/90 kg 1N= 1 kg x m/s2
a= 435 kg x m/s2/ 90 kg
a= 4,8 m/s2
Answer:
Option B. 1,100 Earth diameters
Solution:
Angular position of steroid, (given)
To calculate the distance of asteroid, we use parallax method given as:
(1)
where,
From the relation:
l =
we get:
distance(d) or R =
distance(d) or R =
d =
distance, d =
Comparing it with Earth's diameter:
d =
Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.
Answer:
Explanation:
Formula
Force = mass × acceleration
147N =? × 9.8 ms2
M =
M = 15
Double Check
15 X 9.8
147N
Hope this helps!
