Answer:
Explanation:
The speed of sound in the air increases 0.6 m / s for every 1 ° C increase in temperature. An approximate speed can be calculated using the following empirical formula:
Where:
A more exact equation, usually referred to as adiabatic velocity of sound, is given by the following formula:
Where:
Hence:
Now, the Mach number at which an aircraft is flying can be calculated by:
Where:
Therefore:
Answer:
In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell", followed by the "2 shell", then the "3 shell", and so on farther and farther from the nucleus.
Explanation:
Answer:
2m/s^2
Explanation:
Clculate the acceleration:
V = u +at
20m/s = 0 + a*10s
a = 20m//10s
a = 2m/s²
From the data given , it is not possible to calculate the displacement , because no direction of motion is given
But it is possible to calculate the distance travelled
Distance = ut + ½ *a*t²
distance = 0 + ½ * 2m/s * 10²s
distance = 100m
Answer:
Explanation:
From the question we are told that
Initial speed
Final speed 
Generally the Newtons equation of motion is mathematically represented by
with
Therefore
Therefore
