The volume of the helium balloon in order to lift the weight is 17,760m³.
To find the answer, we need to know about the buoyant force.
<h3>What's the buoyant force?</h3>
- When a lighter object is kept in a higher density medium, it experiences a force along upward by that medium. This is buoyant force.
- Mathematically, buoyant force= density × volume of the object×g
<h3>What's the volume of helium required to lift the 269kg weather balloon and 2910kg package?</h3>
- To lift the weight, the buoyant force must equal to the weight.
- If V is the volume of helium, buoyant force= V×0.179×g
- So, V×0.179×g = (269+2910)g
=> V= 3179/0.179 = 17,760m³
Thus, we can conclude that the volume of the helium balloon in order to lift the weight is 17,760m³.

Answer:
0.25 m
Explanation:
Refraction occurs when the velocity or wavelength of a wave changes at the interface between two media.
We know that refractive index=
Wavelength in medium A/wavelength in medium B = velocity in medium A/velocity in medium B
Let the wavelength of medium B be a
0.5/a = 0.3/0.15
0.5 × 0.15 = 0.3 × a
a= 0.5 × 0.15/0.3
a= 0.25 m

Answer:
The maximum height the pumpkin reaches occurs at 62.5 horizontal meters from its launching spot.
Explanation:
Notice that we are given the actual trajectory equation:
which corresponds to a curve represented by a parabola.
We can find the maximum of this parabola with arms pointing down requesting the derivative (slope of the tangent line to the curve) to be zero :
