Answer:
f = 0.283
Explanation:
With the given values x=5m and t=2s, the acceleration a of the block must be:
(1) 
The sum of all forces in the inclined plane must be:
(2) 
Solving equation2 for the acceleration a:
(3) 
Using equations 1 and 3 to solve for f:

If this question has the same set of options as to the following, the answer would be letter d. Continuity.

The period is the reciprocal of the frequency. (1 divided by it)
Frequency = 261 / 1 second
Period = 1/261 second
= 0.00383... second (rounded)
The Law of conservation states that mass nothing can be created nor destroyed by chemical means.
<span>
You can make a rocket bottle, it shows the a chemical reaction.
</span>baking soda<span> acts as a base, while vinegar an acid. </span><span>The reaction releases gas and it makes carbon </span><span>dioxide
The result is easy even though the substance is mixed, nothing new was created, the formula would be a combination of two substances not a new product. Nothing was destroyed either, therefore it follows the law.</span>
