Answer: The given statement is True.
The proliferation of photosynthetic planktons results in harmful algal blooms. Due to this, the surface of the water body gets completely covered with algal bloom. This blocks the sunlight as it can not penetrate the water. Due to this, photosynthetic planktons are no more able to perform photosynthesis. This ultimately ends up depleting all oxygen from the body of water.
Thus, the given statement is true.
Answer:
both

Answer:
Mass of object = 8kg
Explanation:
- <em>Since</em><em> </em><em>a</em><em>=</em><em> </em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>v</em><em>/</em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>t</em><em>,</em><em> </em><em>a</em><em>=</em><em> </em><em>(</em><em>1</em><em>8</em><em>-16</em><em>)</em><em>/</em><em>2</em>
<em>=</em><em> </em><em>1.5</em>
- <em>And</em><em> </em><em>F</em><em>=</em><em>ma</em><em> </em>
- <em>Force</em><em> </em><em>=</em><em>1</em><em>2</em>
- <em>a</em><em>=</em><em> </em><em>1.5</em>
- <em>m</em><em>=</em><em>?</em>
<em>You</em><em> </em><em>can</em><em> </em><em>now</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>your</em><em> </em><em>unknown</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>mass</em><em>.</em>
Heat absorbed is given by multiplying the specific heat capacity with the mass of the substance and the change in temperature.
specific heat capacity of iron= 460.5 J/kg/k
therefore, heat = mcФ, where c is heat capacity, m is the mass of iron and Ф is change in temperature. Change in temperature is 14 (20-6), mass in kg (0.057 kg)
=460.5 × 0.057 x 14
= 367.48 joules
Hence, heat absorbed by iron will be 367.48 joules
