Answer:
Air.
Explanation:
To know which option is correct, let us consider the relationship between velocity and the wavelength of a wave. This is illustrated below:
Velocity, wavelength and frequency are related by the following equation:
Velocity = wavelength × frequency
v = λf
From the equation above, we can see clearly that the velocity is directly proportional to the wavelength.
This means that an increase in the wavelength will lead to an increase in the velocity and also, a decrease in the wavelength will lead to a decrease in the velocity.
Now, considering the table given in the question above, we can see that the wave has a higher speed in air. This simply means that the wave will also have a higher wavelength in air.
Thus, the correct answer to the question is: air
Answer & Explanation:
<u>use the principle of conservation of momentum</u>
<u>take right as positive and left as negative</u>
<em>momentum is the product of mass and velocity</em>
(4 x 8) + (6 x -2) = (4 x -4) + (6 x Y)
32 - 12 = -16 + 6Y
20 + 16 = 6Y
Y = 6m/s
Final answer the velocity of the 6 Kg ball is 6m/s
The correct answer is tissue.
Compression wrapping is used to reduce swelling and assists with sprains and wounds. If the wrap is applied wrong then this can cause impairment in circulation in the skin, it can cause an abnormal amount of swelling and irritate the skin. Therefore it seems likely that the answer would be tissue.
Under constant acceleration, we have average velocity over a time interval of duration satisfying
where are the plane's initial position and velocity (respectively) and are the plane's position and velocity (respectively) after 9.00 seconds. So
