The velocity of sound in at 300C is 511.3 m/s.
Explanation:
The equation that gives the speed of sound in ar as a function of the air temperature is the following:
where
T is the temperature of the air, measured in Celsius degrees
In this problem, we want to find the speed of sound in ar for a temperature of
Substituting into the equation, we find:
So, the velocity of sound in at 300C is 511.3 m/s.

Answer:
from the position of the center of the Sun
Explanation:
As we know that mass of Sun and Jupiter is given as
distance between Sun and Jupiter is given as
now let the position of Sun is origin and position of Jupiter is given at the position same as the distance between them
so we will have
from the position of the center of the Sun
Answer:
497.00977 N
3742514.97005
Explanation:
= Density of water = 1000 kg/m³
C = Drag coefficient = 0.09
v = Velocity of dolphin = 7.5 m/s
r = Radius of bottlenose dolphin = 0.5/2 = 0.25 m
A = Area
Drag force
The drag force on the dolphin's nose is 497.00977 N
at 20°C
= Dynamic viscosity =
Reynold's Number
The Reynolds number is 3742514.97005
