Answer:
x = 8.74m
Explanation:
Hello! Let's solve this!
Given a mass m = 0.44kg
v = 4m / s
F = 8N
y = 20m
Force on the rocket
F '= F * - (mg) = m * a
We cleared to
a = (F * (- mg)) / m = (F / m) * (- g)
The rocket will accelerate upwards at a time t given by x = v * t
We cleared t
t = x / v
From kinematics we have to
y = (1/2) * a * t2
We replace a and t
y = (1/2) * (F / m) * (- g) * (x / v) 2
We clear x that is the incognita.
x = 8.74m
Answer: 10m look it’s hard but I can say the Explanation
Decreases. Coulomb's Law is based on this, and it basically says, as masses move further apart, their attraction forces become weaker. So, the answer is A.
The object that goes through chemical change, changes completely to where you can not change it back to its original form. Physical change you can undo
There are two types of polymers which are natural and synthetic polymers. Natural polymers do not affect the environment but synthetic polymers do. This type of polymers are produced by humans. These release reactants which are considered hazardous to humans and the environment. Synthetic polymers include rubbers, plastics, and adhesives, and these are considered non-biodegradable and non environmental friendly. As these build up in the environment, in causes problems such as chemical poisoning to all the living things around it. Hope this helps.
