Answer:
$600 (ML), $200 (MW), $1,035 (total raised), $965 (need to raise needed)
Step-by-step explanation:
50 % 50/100 = 0.5
$1200 x 0.5 = $600 Mrs LeBlanc's class has raised
$600/3 = $200 Ms. Warner's class has raised (MW)
600 + 200 + 235.14 = $ 1,035 Has been raised
1,200 - 1,035 = $965 is the amount they still need to raise
Answer:
Given:
Mass of the tennis ball=56.5 g
wavelength=5400 Angstroms
De-Broglie Wavelength = 5400 Angstrom.
= 5400 × 10⁻¹⁰ m.
Now, Using the Formula,
λ = h/mv
here,
h is the Planck's constant = 6.62 × 10⁻³⁴ J-s.
and v is the velocity of the tennis balls.
∴ 5400 × 10⁻¹⁰ = (6.62 × 10⁻³⁴)/ (0.054 × v)
⇒ 0.054v = (6.62 × 10⁻³⁴)/ (5400 × 10⁻¹⁰)
⇒ 0.054v = 0.0012 × 10⁻²⁴
⇒ v = 0.0012 × 10⁻²⁴/0.054
⇒ v = 0.023 × 10⁻²⁴ m/s.
Hence, the velocity of the tennis balls is 0.023 × 10⁻²⁴ m/s.
