The correct answer is:
Descending into earth’s interior, temperature, as well as pressure on rock increases
Explanation:
Temperature and pressure progressively improve with increased proximity to Earth's core. Modern studies register the core's warmth may be close to 11,000 degrees Fahrenheit; that's nearly 2,000 degrees warmer than before deemed and hotter than the exterior of the Sun.
Answer: b. Salt lakes are formed when river bends are cut off.
Salt lakes are formed when water from water sourced gets accumulated in a shallow region and the supply of water is cut. These salt lakes are terminal which means water does not flow to other locations. Therefore, salt lakes are formed when river bends are cut off.
(2nd variant, 7kg is 3 times faster than 21kg)
Answer:
option 5
Explanation:
because all u do is have to add them up
Answer:
The period of the wave does not change looting the value that accompanies the time, the wavelength does not change since it is the constant that accompanies x.
We see that the amplitude is twice the amplitude of the incident waves. Since the wave is stationary the velocity is zero
Explanation:
In this exercise we are given the equation of two traveling waves, it is asked to find the resulting wave
u = f + g
u = 2 sin (x + t) + 2 sin (x-t)
we will develop double angled breasts
u = 2 [(sin x cos t + sin t cos x) + (sin x cos t - sin t cos x)]
u = 2 [2 sin x cos t]
u = 4 sin x cos t
The period of the wave does not change looting the value that accompanies the time, the wavelength does not change since it is the constant that accompanies x.
We see that the amplitude is twice the amplitude of the incident waves. Since the wave is stationary the velocity is zero
