Answer
B. F=ma
Explanation
The Newton's laws of motion tries to explain the how bodies behave and the energy changes when theys are in motion. For the 3 of them to hold, the bodies must be moving in a straight line and with constant velocity.
The second one states that, "the change of momentum of a moving body is directly proportional to the force producing it and it takes place to the direction of force."
From the choices given, the appropriate answer is B. F=ma
Y → Z → X → W
Explanation:
W = 6
X = 5
Y = 1
Z = 3
A convenient scale for expressing the level of acidity or alkalinity of aqueous solutions is the pH or pOH scale.
- The pH of a solution is the negative logarithm to base 10 of the hydrogen ion concentration of the solution.
- The pH scale ranges from 1 to 14 in which case 1 is the lower limit and 14 is the upper limit.
- An acidic solution has a pH value less than 7
- Neutral solutions have pH of 7
- Bases have pH greater than 7

Explanation:
Given that,
The disintegration constant of the nuclide,
(a) The half life of this nuclide is given by :
(b) The decay equation of any radioactive nuclide is given by :
Number of remaining sample in 4.44 half lives is :
So,
(c) Number of remaining sample in 14.6 days is :
So,
Hence, this is the required solution.
