Answer:
B. Landscape B
Explanation:
Shale is fine sediment pressed together to form rock.
Sandstone is larger (sand-grain-sized) sediment cemented together to form rock.
Shale erodes faster, as evidenced by the second attachment. That attachment shows erosion of a rock face consisting of interbedded shale and sandstone. The shale has receded significantly, leaving the sandstone layers with space between them.
Answer:
The waves will turn slightly to the <em><u>left .</u></em>
Explanation :
The waves will turn slightly to the left, because the left side of each wave front hits the boundary first and slows down, moving more slowly than the right side until the right side of the wave front reaches the boundary. THis causes the wave to veer slightly to the left.
Basically the speed of water depends upon depth of the river or the ocean.
the formula is as follows :
v = √gxd
v = √d (g is the gravitational acceleration)
As the water waves are more at the deeper end then the shallow end, so during its course to the shallower end, they are slightly deviated toward the normal., hence it will move slightly to the left.
Argon come from the air. It is a noble gas present in atmosphere. The percentage of argon in air is about 0.93%. Naturally, it is a colorless and odorless gas. When electrifies it gives a blue-green glow. Argon laser is used in field of medicine and surgery.
Answer:
t = 47 years
Explanation:
To find the number of years in which the electrons cross the complete transmission, you first calculate the drift velocity of the electrons in the transmission line, by using the following formula:
(1)
I: current = 1,010A
A: cross sectional area of the transmission line = π(d/2)^2
d: diameter of the transmission line = 2.00cm = 0.02 m
n: free charge density = 8.50*10^28 electrons/m^3
q: electron's charge = 1.6*10^-19 C
You replace the values of all parameters in the equation (1):

with this value of the drift velocity you can calculate the time that electrons take in crossing the complete transmission line:

Finally, you convert this value of the time to years:

hence, the electrons take around 47 years to cross the complete transmission line.
