Answer:
0.625 g/m
Explanation:
The fundamental frequency of a tensioned string is:
f = √(T/ρ) / (2L)
where T is the tension,
ρ is the mass per length linear density,
and L is the length of the string.
Solving for ρ:
2Lf = √(T/ρ)
4(Lf)² = T/ρ
ρ = T / (4(Lf)²)
Given T = 100 N, L = 2 m, and f = 100 Hz:
ρ = 100 / (4 (2×100)²)
ρ = 100 / (4 × 40000)
ρ = 1/1600
ρ = 0.000625 kg/m
ρ = 0.625 g/m
<span><em>IF</em> all the bulbs are <u>identical</u> bulbs . . .
. .
All the bulbs in series have the same brightness, and that
brightness
depends on how many there are. More bulbs ... all are
equally less bright.
Fewer bulbs ... all are equally brighter.</span>
If the bulbs are not all identical, then it depends on what each one is, which one
was removed, etc., and it can get complicated.
Answer:
pretty sure it's true....
False, Carbon usually forms four covalent bonds.
Answer:
1.4719 m per sec
Explanation:
Hello
Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy
the formula to use is
where m is the mass of the object and v the velocity
lets see the kinetic energy of the sprinter running
Now, the elephant must have the same kinetic energy
it works only the positive root, so the elephant must to walk to 1.4719 m/s to have the same kinetic energy.
Have a great day
