This answer to the question is True
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

An original sample of K-40 has a mass of 25.00 grams.
After 3.9 m 109 years, 3.125 grams of the original sample remains unchanged.
What is the half-life of K-40?
First step is to determine the remaining decimal amount.
3.125 grams /25.00 grams = 0.125
Second step is to determine the number of half lives.
(1/2)^n = 0.125
N log (1/2) = log 0.125
N = 3 years
Answer:
43.96secs
Explanation:
M1 = molar mass of NH3 = 14 + (3x1) = 14 + 3 = 17g/mol
t1 = time for NH3 to diffuse = 30secs
M2 = molar mass of HCl = 1 + 35.5 = 36.5g/mol
t2 = time for HCl to diffuse =?
From Graham's law of diffusion:
t2/t1 = √(M2/M1)
t2/30 = √(36.5/17)
t2/30 = 1.465
Cross multiply
t2 = 30 x 1.465
t2 = 43.96secs
Therefore it will take 43.96secs for the damp blue litmus paper to change colour for HCl.
Answer: The second law of newton states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and also the mass of the object.
