Answer:
we don't care what ure saying thats absurd
Answer:
The formula for calculating Density is:
= Mass / Volume
From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.
If mass however was decreasing, density would have to decrease as well.
For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.
Density of 5kg brick = 5 / 5 = 1 kg/m³
Density of 10kg brick = 10 / 5 = 2kg / m³
Density of 15kg brick = 15 / 5 = 3 kg /m³
<em>Notice how density increases as mass increases and decreases when mass decreases. </em>
Given:
object = 20kg
terminal speed of object = 80 m/s
According to the problem, drag force is proportional to speed, so Fd = kv ; k is some constant
At terminal velocity Vt: Fg = Fdmg = kVtk = mg / Vt = (20.0)(9.8)/(80.0) = 2.45 kg/s
<span>Fd = kv = 2.45v</span>
Fd = 2.45 (30.0) = 73.5 N
Answer:
This atom has nine electrons
Explanation:
I just did it and I got it right.
Part a)
Centripetal acceleration is defined as
now here we know that
m = 3 kg
now from above formula we have
Part b)
Maximum possible tension in the string is given as
now by force equation we have
now again by above formula
