Answer:
Its simple! B The ball accelerates upward!♡♡
Answer:
563.86 N
Explanation:
We know the buoyant force F = weight of air displaced by the balloon.
F = ρgV where ρ = density of air = 1.29 kg/m³, g = acceleration due to gravity = 9.8 m/s² and V = volume of balloon = 4πr/3 (since it is a sphere) where r = radius of balloon = 2.20 m
So, F = ρgV = ρg4πr³/3
substituting the values of the variables into the equation, we have
F = 1.29 kg/m³ × 9.8 m/s² × 4π × (2.20 m)³/3
= 1691.58 N/3
= 563.86 N

It's called d. a glissando (glissando means "to slide" - which is how you play one)
Answer:
The net outward force is exerted on a square window of the house is
.
Explanation:
Given that,
Pressure = 1.02 atm
External air pressure = 0.910 atm
Distance = 2.03 m
We need to calculate the net outward force
Using formula of force

Where, P = pressure
F = force
A = area
Put the value into the formula


Hence, The net outward force is exerted on a square window of the house is
.
