Answer:
200 C
Explanation:
Let C1 and C2 be their charges. According to Coulomb's law
where k = 
is the constant, R = 0.4m is the distance between them, F = 120 N is their resulting charge force
Since their total charge is 200C:
or 
We can substitute the above equation
or 
So the larger charge is C = 200 C
Answer:
The flag will appear to be black.
Explanation:
This is because red is the only brighter color in the American flag, so when a blue light is shined, the red turns dark and then the flag looks just blank and black.
The time of motion of the ball before coming to rest is determined as 5.5 s.
<h3>
Time of motion of the ball</h3>
The time of motion of the ball before coming to rest is calculated as follows;
v = u + at
when the ball comes to rest, v = 0
0 = u + at
0 = 55 + (-10)t
0 = 55 - 10t
10t = 55
t = 5.5s
Thus, the time of motion of the ball before coming to rest is 5.5 s.

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.
