Hi there!
We can begin by doing a summation of forces for each block.
Block A:
This block has the force of tension (in direction of acceleration +) and static friction (opposite direction -) acting on it. Thus:
Block B:
This block has the force of tension (opposite of acc. -) and gravity (in direction of acc +), working on it.
Add both of the expressions and solve for the maximum mass of Block B.
To find the minimum value, we can set a = 0, so:
The block must weigh <u>> 16 kg</u> for block A to move.
Answer:
Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20). The chemical equation for this reaction is written as: The '+' is read as 'reacts with' and the arrow '' means 'produces'.

Answer:
65 years
Explanation:
The arc that ends at 4000 Hz intersects the 20 db hearing intensity at 65 years.
A bolt of lightning<span>, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case, its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit)
</span><span>So,it can be around 30,000 degrees.The answer is Choice A.</span>
The answer is C. I hope this helps you.
