Answer:
The body with 2.7
has a larger volume
Explanation:
There is a missespelling in the question. The units of density cannot be g, they usually are 
In order to answer this question, we need to use the formula of the density of a body:

For body A:
Mass (M) = 5.0 g
Density (D) = 2.7 
2.7
= 5g * 1/V
V1 = 5g / (2.7
)
V1 = 1.85 
For Body B:
Mass (M) = 5.0 g
Density (D) = 8.4 
8.4
= 5g * 1/V
V2 = 5g / (8.4
)
V2 = 0.59 
So V1 is bigger than V2
A car traveling at
20 m/s starts to decelerate steadily it comes to a complete stop in 10s. The
equation for the acceleration is velocity divided by time. So divide 20 m/s by
10 s and you will get an acceleration of 2 m/s2.
Gravity is pulling the skydiver down therefore gravitational force
Hi,
your answer would be false. But it seems you already knew that.
I hoped I helped and if you need help you could always ask me :)
