The oxygen is the Solute, since this is smaller in quantity.
The Nitrogen is the Solvent, since this is more in quantity.
The air is the Solution, this is the mixture itself.
Answer:
270Joues
Explanation:
Step one:
given data
Force F= 45N
distance moved d= 6m
Required
The work done in moving the block 6m
Step two:
We know that the expression for the work done is
WD= force* distance
WD= 45*6
WD=270Joues
Answer:
The runner's acceleration was 
Explanation:
<u>Constant Acceleration Motion</u>
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
Solving for a:
The runner speeds up from vo=5 m/s to vf=9 m/s in t=4 seconds, thus:
The runner's acceleration was
Answer:
gravitational force is a force while gravity is a fundamental quantity
Explanation:
Because you know that gravity is in m/s^2 so, period will be measured in seconds. You know the cable is 12m long and gravity is 9.81 solve for T (period) 2π12sqrt(9.81)=6.94922
