The first five questions refer to the following problem: A model rocket lifts off with an upward thrust of 35 Newtons. It has a mass of 2.5 kilograms and a weight of 25 Newtons. How quickly does the rocket accelerate?

What quantity is this problem asking you to solve for?

Question 1 options:

Mass

Acceleration

Force

Velocity

The Acceleration of a model rocket = 4 m/s²

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

An upward thrust of 35 N

A model rocket has a mass of 2.5 kg(weight = 25 N)

so resultant force :

The acceleration :

air quality

poor drinking water

and heavy polution

can lead to poor health

beta decay is the answer
