Answer:
Option A. 6.75 (6.20/85.6)
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 6.2cm³
Initial concentration (C1) = 6.75M
Final volume (V2) = 85.6cm³
Final concentration (C2) =.?
The final concentration can be obtained by using the dilution formula as show below:
C1V1 = C2V2
6.75 x 6.2 = C2 x 85.6
Divide both side by 85.6
C2 = (6.75 x 6.2) /85.6
C2 = 6.75 (6.2 / 85.6).
Answer:
b. bread turns brown in the toaster
Answer:
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
Time graph plots acceleration values on the y-axis, and time values on the x-axis. In this graph, the acceleration remains constant at 2.0 m/s/s for 10 seconds. Acceleration is defined as a change in an object's velocity, so if an object is accelerating at 2 m/s/s, then every 1 second, the object will gain 2 m/s.

Answer: Yes, Digital formats carry more data per second than analog formats
Explanation: The transmission of data from one area (point A) to another area (point B) is refered to as a signal. This signals can be transmitted from point A to point B through two different medium and formats, namely; analog formats and the digital format.
In the analog format, the data is converted into electrical pulse before it's been sent while in digital, data is been converted into binary format representing two amplitude before been sent. Note that devices or machines are at point b (destination) which will collect this pieces of information an convert them into readable and interpretable sounds or image.
Analog signals are a bit old and there is limitation on the size of data that can be transmitted in this formats.
The digital signal is more modern and it carry more data per second compared to the Analog.
So digital formats can hold more data than the analog.
