An Egyptian pylon can best be described as a massive gateway with sloped sides. The two structures on each side are usually rectangular in size. The first pylon was constructed in ancient Egypt and is believed to be called Philae.
Answer:
On the oceans of the Earth, gravity and inertia work in opposition, causing tidal bulges on opposite sides of the planet. The moon's gravitational force pulls the ocean's waters toward it on the "near" side of the Earth (the side facing the moon), resulting in a bulge.
Explanation:
Answer:
Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. ... This process, known as “longshore drift,” can cause significant beach erosion.
Explanation:
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
