Answer:
r2/r1 = 1.3
Explanation:
Electric field is given as:
E = kq/r²
At a distance r1,
226 = kq/(r1)² - - - - - - - - - - - - - (1)
At a distance r2,
134 = kq/(r2)² - - - - - - - - - - - - - (2)
From (1),
kq = 226 * (r1)²
From (2),
kq = 134 * (r2)²
Equating and then solving,
134 * (r2)² = 226 * (r1)²
(r2)²/(r1)² = 226/134
(r2)²/(r1)² = 1.687
=> r2/r1 = 1.3
I believe it is the nervous system.
Answer:
When there is no force acting on a body then a moving object move in a straight line with constant velocity and an object in rest stays in rest.

Coordinator bond ! the three bond pair makes triple bond !
Answer:
a = 12 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
ΣF = m*a
where:
ΣF = sum of forces acting on a body [N] (units of Newtons)
m = mass = 0.5 [kg]
a = acceleration [m/s²]
Let's take the direction of positive forces to the right and negative forces directed to the left
2 + 8 - 4 = 0.5*a
6 = 0.5*a
a = 12 [m/s²]
