Explanation:
Formula to calculate angular acceleration is as follows.
or, 
Putting the given values into the above formula as follows.
= 
= 0.326 
Thus, we can conclude that the wheel’s angular acceleration if its initial angular speed is 2.5 rad/s is 0.326 .
The wavelength will remain unchanged.
Explanation:
The velocity 
of a wave in terms of its wavelength 
and frequency 
is
(1)
so if we double both the velocity and the frequency, the equation above becomes
(2)
Solving for the wavelength from Eqn(2), we get
We would have gotten the same result had we used Eqn(1) instead.
Answer:
In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land. ... Seas are smaller than oceans and are usually located where the land and ocean meet.
It’s due to the refraction of light rays as they traverse the boundary between water and air. The greater the viewing angle, the more the bending of the light and therefore the less the apparent depth. An object placed in a denser medium, when viewed from rarer medium appears to be at a lesser depth than its real depth due to refraction of light.
Answer:
62.1 ft
Explanation:
We know that 
hence 240 gpm will be
From the formula of obtaining efficiency
and making 
the subject we have
where Q is flow rate, 
is specific weight of water, is actual head rise and 
is the power input to the compressor
Substituting 0.62 for 
, 6hp for , 
for and 
for Q then
Therefore, actual head rise of the water being pumped is 62.1 ft
