The finding that attention can spread within an object, thereby, enhancing detection at other places within the object is referred to as
a. ? spatial drift
b. ? spreading activation
c. ? same-object advantage
d. ? object location invariance

The finding that attention can spread within an object, thereby, enhancing detection at other places within the object is referred to as same-object advantage effect (SOA). The effect is that the performance of observers who are judging two targets is better (faster and/or more accurately) when they are from the same object than when they are from different objects.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

Answer: a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same sign as the  -4.0  µc charge.======electricstatic force between two point charges  is given by    where k is coulomb's constant,  8.99×10⁹  n·m²/c², q₁ and q₂ are the point charges, and r is the distance between the two point charges.assign positive to q₁let q₁ =  6.0 µc, q₂ = -4.0  µc, q₀ represent the charge at the origin, and q₃ represent this new charge to place.the charge at the origin q₀ would experience the following force f₀₁ from q₁, with r = 6.0 m (note that 1  µc = 10⁻⁶ c)    the force from q₂    the force from q₃    the net force on the origin charge, q₀, has to be zero for no electrostatic forcehaving an equation where k and q₀ can be divided out of the equation will allow us to solve for q₃    isolating:     a charge of -1.0  × 10⁻⁴ c must be placed  at x = 26 m.the sign of the charge will be the same as the  -4.0  µc charge
