Answer:
Speed of air = 1106.38 ft/s
Explanation:
Speed of sound in air with temperature

Here speed is in m/s and T is in celcius scale.
T = 50°F

Substituting

Now we need to convert m/s in to ft/s.
1 m = 3.28 ft
Substituting

Speed of air = 1106.38 ft/s
Answer:
The answer is below
Explanation:
We are to check if the statement is true of false. If it is false, we correct the statement.
Solution:
Acceleration is the time rate of change of velocity. It is the ratio of the change in velocity to the change in time. The acceleration can be gotten from a velocity time graph by finding the slope of the graph.
The x coordinate represent the time and the y coordinate velocity.
5) Graph A passes through the point (0, 0) and (4, 24). Therefore the acceleration (slope) is:
Acceleration = 
This is correct.
6) Graph B is a straight line of 12 m/s. It passes through (0, 12) and (4, 12). Hence:
Acceleration = 
This is false.
Therefore the acceleration of graph B is 0 m/s².
Answer:
It is a gene!!
Explanation:
It is because RNA is referred to as a gene. Genes are contained in chromosones.
No because you don’t learn about synthetic inventions yet in your first year
