Answer:
C. The frequency stays the same and the wavelength decreases
Explanation:
The speed of a wave, 'v', is given as follows;
v = Frequency, f × Wavelength, λ
∴ v = f × λ
Therefore, the speed of the wave is directly proportional to the wavelength
v ∝ λ
When the speed of the sound wave increases as it enters a new medium, we have that frequency of the wave, which is determined at the source, remains the same, while the wavelength of the wave increases
As 'v' increases, λ increases
Therefore, for an increase in velocity of the wave, the frequency of the wave stays the same and the wavelength increases.
Answer:
Taking gravity to be 9.8m/s2, The velocity is 24.5m/s2.
Taking gravity to be 10m/s2, The velocity is 25m/s2.
Explanation:
According the first formula of motion under the influence of gravity for upward motion, v=u-gt, where v=final velocity, u=initial velocity, and t= time taken.
Here the time taken for the ball to reach the maximum point is half of 5, which is 2.5 seconds.
And v is 0, since at the maximum point gravity slows down the velocity to 0.
Finding the initial velocity,
v=u-gt
0=u-10(2.5)
u=10(2.5)
u=25m/s
The acceleration of gravity on Jupiter is listed as <em>24.79 m/s²</em> .
That's roughly 2.53 times its value on Earth. So if you weigh, let's say,
130 pounds on Earth, then you would weigh about 328 pounds on Jupiter.
I would say your answer is...... The strongest voice in shaping foreign policy belongs to the President.
It is declared under the United States constitution that the President
gets to decide foreign policy, but the Congress is allowed to ratify
treaties.
