Answer:
The magnification is 
Explanation:
From the question we are told that
The object distance is 
The focal length is 
From the lens equation we have that
=> 
substituting values
=> 
=> 
The magnification is mathematically represented as
substituting values
This equation is one of the most useful in classical physics. It is a concise statement of Isaac Newton's<span> Second Law of Motion, holding both the proportions and vectors of the Second Law. It translates as: The net force on an object is </span>equal<span> to the </span>mass<span>of the object multiplied by the </span>acceleration<span> of the object.</span>
64. 16x16 = 4 so 9x9 divided by 2 equals 7
Answer:
force is 96 N
Explanation:
given data
mass = 40 kg
acceleration = 2.4 m/s²
to find out
force
solution
we know force is mass time acceleration so
we will apply here force formula that is express as
force = m × a ..............1
here m is mass and a is acceleration so
put here value in equation 1 we get force
force = 40 × 2.4
force = 96
so force will be 96 N
