Answer:
The earths magnetic field
Explanation:
Average acceleration: velocity/time
5/4= 1.25 m/s² Acceleration
Hope I helped :)
1. 0.2 g/mL
The relationship between mass, density and volume of an object is
where
d is the density
m is the mass
V is the volume
For the object in this problem, we have
m = 10 g
V = 50 mL
Substituting into the equation,
2. 10 mL
In this exercise we know:
- The density of the object: d = 2 g/mL
- The mass of the object: m = 20 g
Therefore, we can re-arrange the previous equation to find the volume:
And substituting values into the equation, we find
Density = mass / volume
D = 89 / 10.0
D = 8.9 g/cm³
hope this helps!
