Answer:
Explanation:
We shall find the volume of stored gas at atmospheric pressure .
P₁ V₁ = P₂ V₂
15.5 x 10⁶ x .02 = 10⁵ x V₂ ( atmospheric pressure is 10⁵ Pa )
V₂ = 3.1 m³
volume of one balloon = 4/3 x π r³ , r is radius of balloon
= 4/3 π x .11³
= .050658 m³
no of balloon = total volume to be filled / volume of one balloon
= 3.1 / .050658
= 61 .2
= 61
(F)(M)=A
Force times Mass equals Acceleration.
The answer is TRUE.
If the mass increases the number on the left side of the equation increases, thus increasing the right side as well.
Answer:
equilibrium position.
Explanation:
In simple harmonic motion , velocity v(t) is given by,
v(t) = -ω A sin(ωt + φ)
where
ω = angular velocity of the corresponding circular motion
A = amplitude
t = time
φ = the initial angle of the corresponding circular motion when the motion begin.
v (t) get maximized when sin value is maximized , i.e. sin 
=1
The particle has maximum speed when it passes through the equilibrium position.

The exact location of electrons in electron shells of atoms cannot be exactly ascertained. This is why VSPER atomic models represent the position of electrons (s, p, d, & f) using the probability of where they would most be expected to be found.
Explanation:
This is because merely observing electrons changes their behavior. Remember that to observe something one has to shine light on it so it bounces back to the eye. Due to the negligible mass of electrons, mere photons of light will change their direction of movement, spin or other behaviors/properties.

Answer:
Force = 125 [N]
Explanation:
In the attached image we can see a sketch of the lever system.
And if we make a sum of moments at the point O equal to zero (0).
In the equation showed in the image, we can determinate the force that we need
