B: an increase in acceleration caused an increase in force.
This is based on the concept of force on an object.
Now, formula for force is commonly known as;
Force = mass × acceleration
Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.
- Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.
Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.
Moreover, the force is directly proportional to the acceleration!
Thus, we can say that an increase in acceleration caused an increase in force.

Chemical Reaction between metal oxide and water solution
Answer: Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your school, home and businesses.

If the net force on a block is zero, the block will move at constant velocity
Explanation:
We can answer this question by applying Newton's second law of motion, which states that the net force on an object is equal to the product between its mass and its acceleration:
(1)
where
is the net force on the object
m is its mass
a is its acceleration
In this problem, we have a block, and the net force on it is zero:
According to eq.(1), this also implies that
So, the acceleration of the block is zero.
However, acceleration is the rate of change of velocity of a body:
where 
is the change in velocity in a time of 
. Since the acceleration is zero, this means that 
, and therefore the velocity of the object is constant.
