The density (d) of a substance is calculated by dividing the mass (m) by the given volume (v). Mathematically,
d = m / v
Substituting the known values,
d = 374 g / (2.2 x 10^3 L) = 0.17 g/L
Thus, the density of the weather balloon is 0.17 g/L.

why we follow ur order..........
Mostly when your around carpet or anything related to a carpet because when you do it long enough you will generate static electricity i hope this helps
Answer:
t = 0.37 seconds
Explanation:
t = (1/4)T
Maximum acceleration is;
a_max = Aω²
In simple harmonic motion, we know that v_max = Aω
Thus, a_max = v_max•ω
ω = a_max/v_max
We know that Period is given by;
T = 2π/ω
From initially, t = (1/4)T so, T = 4t
Thus, 4t = 2π/(a_max/v_max)
t = (2π/4)(v_max/a_max)
We are given;
Maximum velocity;v_max = 1.47 m/s
Max acceleration;a_max =6.24 m/s²
Thus,
t = (2π/4)(1.47/6.24)
t = 0.37 seconds
Answer:
high tension: 4.2 × 1.5 = 6.3 cm/s
medium tension: 2.8 ×1.5 = 4.2 cm/s
low tension: 0.8 × 1.5 = 1.2 cm/s
Explanation: Given Settings:
amplitude: 0.75 cm
damping: zero
Using
Speed = frequency ×wavelength
Where
Wavelength = 0.75 × 2 = 1.5 cm
Therefore:
high tension: 4.2 × 1.5 = 6.3 cm/s
medium tension: 2.8 ×1.5 = 4.2 cm/s
low tension: 0.8 × 1.5 = 1.2 cm/s
