Answer:
1.The main purpose of lab is to perform different experiments and importance of topic is that it supports essay's thesis statement.
Explanation:
The amount of air resistance<span> an </span>object<span> experiences depends on its speed, its cross-sectional area, its shape and the density of the </span>air<span>. </span>Air<span> densities vary with altitude, temperature and humidity. Nonetheless, 1.29 kg/m</span>3<span> is a very reasonable value. The shape of an </span>object affects<span> the drag coefficient (C</span>d<span>)</span>
Answer:
<h2>The answer is 250 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 250 mL
density = 1 g/mL
So we have
mass = 250 × 1
We have the final answer as
<h3>250 g</h3>
Hope this helps you
