Answer:
<h2>2000 N</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 500 × 4
We have the final answer as
<h3>2000 N</h3>

111.1 mL of water
Explanation:
Weight per volume concentration (w/v %) is defined as
weight per volume concentration = (mass of solute (g) / volume of solution (mL)) × 100
volume of solution = (mass of solute × 100) / weight per volume concentration
volume of solution = (1 × 100) / 0.9 = 111.1 mL
volume of water = volume of solution = 111.1 mL

The mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.
<h3>DENSITY:</h3>
- The mass of a substance can be calculated by multiplying the density of the substance by its volume. That is;
Mass = density × volume
- According to this question, the volume of the salt is 550mL while its density is given as 1.50g/mL. The mass is calculated as follows:
Mass = 1.50g/mL × 550mL
Mass = 825grams.
Therefore, the mass in grams 550 mL of salt water with a density of 1.50 g/cm³ is 825grams.

Answer:
Our Solar System may be home, but researchers are now discovering that it's not really much like the other kids. According to a survey of 909 planets orbiting 355 stars, our home planetary system is a little on the dishevelled side - and others are a lot more orderly.
