Answer:
the Jack speed is greater than the Nas speed
v₁ = 2.08 m / s > v2 = 1.85 m / s
Explanation:
For this exercise we can find the average speed of each of the boys, the average speed is defined as the displacement in the time interval
v = x / t
Jack.
It tells us that it travels x = 15 km in a time of t = 2 h
let's reduce the magnitudes to the SI system
x = 15 km (1000 m / 1 km) = 15 10³ m
t = 2 h (3600 s / 1 h) = 7200 s
let's calculate
v₁ = 15 10³/7200
v₁ = 2.08 m / s
Nas travels a distance of x = 10 km in a time of t = 1.5 h
x = 10 km = 10 10³ m
t = 1.5 h (3600s / 1h) = 5400 s
let's calculate the speed
v2 = 10 10³/5400
v2 = 1.85 m / s
From these results we can see that the Jack speed is greater than the Nas speed
Answer: what are the answers?
Explanation:
Physical property is defined as a property that can be observed without changing the matter into another type of matter.
<h3>What are physical properties of matter?</h3>
Physical properties of matter are those properties which can be easily observed without a change in the composition of the substance,
Some physical properties of matter include:
- Volume
- Shape
- Density
- Taste
- Color
- Mass
- Electrical conductivity
In conclusion, physical properties do not change the composition of matter and can easily be observed.
