Answer: Block # 1 , Block # 4 and
Block # 5 will sink.
Block # 2 and 3 will float.
Explanation: The density of water is equal to 1 g/mL. Any density that is less than the density of water will float. Objects with higher density compared to water will eventually sink.
Aluminum is light and is quite unreactive it is malleable and strong too.
Answer:
<h3>The answer is 1.28 N</h3>
Explanation:
The force acting on an object given the mass and acceleration we use the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 142 g = 0.142 kg
acceleration = 9 m/s²
We have
force = 0.142 × 9 = 1.278
We have the final answer as
<h3>1.28 N</h3>
Hope this helps you
Answer:
12.5g
Explanation:
1. Percentage of solution = 5.
2. Mass of solution = 250g.
3. = Mass of solute / 250 x 100.
4. = 5 x 250 / 100.
5. = 12.5g.
