If f=140hz
speed=?
wavelength=?
without all information given, it would be difficult to answer but the formula is speed=frequency ×wavelength
1. stone
s=9,5m
a=g≈10m/s²
t1=?
s=(at²)/2
2s=at²
2s/a=t²
t=√(2s/a)=√(2*9.5m/10m/s²)=√(1,9s²)≈1,38s
2. sound
s=9,5m
V=343m/s²
t2=?
V=s/t
Vt=s
t=s/V=9,5m/343m/s≈0,03s
-------------------------------------------------
V1+V2=1,38s+0,03s=1,41s

Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.
In 4.5 billion years, amount of mass lost = 1000 kg/s * (4.5 * 10⁹ * 365 * 60 60 * 24) = 1.41912 * 10¹⁷ kg.
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.
