Answer:
A.) 2000N
B.) 0
C.) 1414.2 N
Step-by-step explanation:
Given that the force on the rope = 1000N
A.) If the two students pull in the same direction, the resultant force will be addition of the two forces. That is
1000 + 1000 = 2000 N
B.) If the two students pull in the opposite direction, the resultant force will be sum of the two forces equal to zero. That is,
F1 + F2 = 0
F1 = positive 1000N
F2 = negative 1000N
Therefore, 1000 - 1000 = 0
The resultant force of the two forces is zero.
C.) If the two forces are at right angles, south and east to each other, the resultant force R will be achieved by using pythagorean theorem.
R = sqrt( 1000^2 + 1000^2 )
R = sqrt( 2000000 )
R = 1414.2 N
The resultant force of the two forces will be 1414.2N
We know that
<span>1. The number of all 4-letter words written using the alphabet of 20 symbols (from A to T) is
20</span><span>^4=160,000

2. The number of all 4-letter words written using the alphabet of 19 symbols (from B to T) is
19</span><span>^4=130,321

3. The difference represents exactly the number of all words of the inhabitants of the island of Jumble
difference=</span>(160,000-130,321)= 29679.
the answer is
29679

___________
1 5 13 23 52
x^3+5x^2+13x+23+ (52/(x-2))
The answer is 3k+j since 3 cannot be multiplied after k.
