Answer:20n Force :Right
Explanation:
The Answer To the equation is 20n because If the net force is opposite ways you subtract and the net force is the highest number !
8.854 m/s is the speed of the box after it reaches bottom of the ramp.
<u>Explanation</u>:
From the figure we came to know that height of the block is 4 m.
We know that,
Total "initial energy of an object" = Total "final energy of an object
"
Total "initial energy of an object" is = "sum of potential energy" and "kinetic energy" of an object at its initial position.
Initial velocity is “0” as the object does not have starting speed
Total initial energy = 39.2 × m
Now, Total initial energy of an object = Total final energy of an object
Final speed is 8.854 m/s.
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:
1845.26 ?
Explanation:
18.46 × 99.96= 1845.2616 = 1845.26
im not entirely sure though
Answer:
Wind the long piece of thin wire around the uniform glass rod multiple times, find the length of the total diameters using the metre ruler, and divide by the number of times you wound it around the rod.
Explanation:
Since the diameter of one long piece of thin wire is too thin to be measured by a metre ruler, you can wind it multiple times and push it side by side to get a length you can measure.
For example, if you wound it around 20 times and the total length of 20 diameters of the wire side-by-side is 2.0 cm, one winding, which is the diameter would be 2.0cm ÷ 20 = 0.10cm or 1mm.
