Answer:
green
Explanation:
the the board is going to be green
Answer: a) 50
Explanation:
This implies that the controller must be visible at not more than 50ft which is 15m
the object has kinetic energy, because it is on the move!!
Let, 1st force = a
2nd force = b
A.T.Q,
a+b = 10
a-b = 6
Calculate for a & b, you'll get a=8 & b= 2
After increasing by 3, it'll be a = 8+3 = 11 & b=2+3 = 5
Resultant force at 90 degree angle = 11+5 = 16 Newtons
Answer:
direction : West to East
magnitude : 6.0 * 10^-3
Explanation:
<em>Given data :</em>
Four ( 4 ) monitoring wells
location of wells = corners of 1-ha square
Total piezometric head in each well ;
NE corner = 30.0 m ;
SE corner = 30.0 m;
SW corner = 30.6 m;
NW corner = 30.6 m.
<u>Calculate for the magnitude and direction of the hydraulic gradient </u>
first step ; calculate for area
Area = ( 1 -ha ) ( 10^4 m^2/ha )
= 1 * 10^4 m^2
Distance between the wells = length of side
= √( 1 * 10^4 ) m^2
= 100 m
Direction of Hydraulic gradient is from west to east because the total piezometric head in the west = Total piezometric head in the east
Next determine The magnitude of the hydraulic gradient
= ( 30.6 - 30 ) / 100
= 6.0 * 10^-3
