Answer:
Newtons second law (f=m×a)
Explanation:
The mount of force put into the straw or onto the balloon impacts the acceleratoion and is effected by the mass.
Answer:
Q = 8 μC
Explanation:
The relation between voltage, capacitance and charge can be expressed using the following rule:
Q = C * V
where:
Q is the amount of charge that we want to calculate
C is the capacitance = 4 * 10⁻⁶ F
V is the voltage applied = 2 V
Substitute with the givens in the above equation to get the amount of charge as follows:
Q = C * V
Q= 4 * 10⁻⁶ * 2
Q = 8 * 10⁻⁶ Coulumb
Q = 8 μC

<em>1) 26m/s</em>

<em>Hi there !</em>
<em>1)</em>
<em>a = (v₂ - v₁)/t => at = v₂ - v₁ => v₂ = at + v₁</em>
<em>v₁ = 72km/h = 72000m/3600s = 20m/s</em>
<em>v₂ = 2m/s²ₓ3s + 20m/s</em>
<em>= 6m/s + 20m/s</em>
<em>= 26 m/s</em>
<em>2)</em>
<em>d = v₁t + at²/2</em>
<em>= 20m/sₓ3s + 2m/s²ₓ9s²/2</em>
<em>= 60m + 9m</em>
<em>= 69 m</em>
<em>Good luck ! </em>
The total force in each direction has to be the same.
The total force of the blue team is
(220 + 340 + 180 + 560) = 1,300 N
The three members of the red team add up to
(250 + 160 + 420) = 830 N
In order to exactly match the 1,300 N of the blue team,
the fourth red-team guy must contribute an additional
(1,300 - 830) = 470 N .
