You first find the mass and the volume of that object. Then you divide mass ÷ volume
Answer:
The steps are outlined in the explanation below.
Explanation:
The average velocity is derived midpoint from the initial to the final velocity. Here is the proof:
Find the total displacement:
let the displacement be given by the letter s
Then since the average velocity is defined as: 
where t = final time
t₀ = initial time
v = final speed
v₀ = initial time
where x denotes the position, then
where v = 
and dx = change in distance with respect to time.
<u>Increase the thickness of the wire</u> would decrease the resistance in a wire
Explanation:
Thicker wires have a larger cross-section that increases the surface area with which electrons can flow unimpeded. The thicker the wire, therefore, the lower the resistance.
Thin wires have very high resistance the reason the thin tungsten in a bulb glows because it is heated from the high resistance of many electrons trying to pass through a very small cross-section.
Both systems have benefits and disadvantages.
Benefits of the Metric System
<span>Easier for anything involving conversions.Celsius is based on the the freezing and boiling points of water.Is the most popular system of measurement worldwide. This gives interchangeability internationally.Other systems of measurement, like U.S. standard units, are tied directly to metric units so they can be converted back and forth.<span>You can sell to the government since governments (including the U.S. government) require government contractors to use the metric system for most things.</span></span>
Here since both children and merry go round is our system and there is no torque acting on this system
So we will use angular momentum conservation in this
now here we have
Now when children come to the position of half radius
then we will have
now from above equation we have
