The block’s average speed : 0.36 m/s
<h3>Further explanation</h3>Distance is the length traveled by an object within a certain of time .
Average speed = total distance/total amount of time ,
Can be formulated :
ΔD= total distance
Δt= total time
A block is pulled 0.90 m to the right in 2.5 s :
ΔD= total distance = 0.9 m
Δt= total time = 2.5 s
The block’s average speed :
Answer:
<h2>Density = 0.5 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass = 60 g
volume = 120 mL
Substitute the values into the above formula and solve
That's
<h3>We have the final answer as
<h3>Density = 0.5 g/mL</h3>Hope this helps you
Answer:
m = 20.9 g.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by recalling both the Avogadro's number for the calculation of the moles in the given molecules of calcium phosphate and the molar mass of this compound in order to secondly calculate the mass as shown on the following setup:
