A false positive<span> is a conclusion that some effect occurred when in fact it did not. hope it helped but i am not 100%
</span>
The answer is B because it literally says it right there, and I don't wanna make it impossibly confusing for a middle school student, lol.
Answer:
-1 m/s
Explanation:
From the law of conservation of linear momentum, the sum of initial and final momentum should be equal. Momentum, p is expressed as the product of mass and velocity. Therefore, p=mv where m and v represent mass and velocity respectively. In this case

Where subscripts d and u represent downwards and upwards respectively while c is common hence common velocity which is unknown in this case. Taking downwards as negative while upwards as positive then substituting -3 m/s for downward speed while 3 m/s for upward speed, the masses as given then
(2*-3)+(1*3)=(2+1)v
V=-1 m/s hence downward direction
Answer:

Explanation:
Given that,
The masses of two objects, m₁ = m₂ = 1 kg
The distance between masses, d = 1 m
We need to find the gravitational force between two masses. The force is given by the relation as follows :

So, the force between two masses of 1 kg is
.
