The mass of water is 0.139 kg
Explanation:
The density of a substance is given by the equation
where
is the density
m is the mass of the substance
V is its volume
In this problem we have:
V = 139 mL is the volume of water
The density of water is:
Solving the equation for m, we find its mass:
And converting into kilograms,

Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
