Answer:
Before: 0 m/s
After: -4 m/s
Explanation:
Before: Since you and your beau started at rest, your beau initial velocity is 0 m/s.
After: Since we have to conserve momentum,
momentum before push = momentum after push.
The momentum before push = 0 (since you and your beau are at rest)
momentum after push = m₁v₁ + m₂v₂ were m₁ = your mass = 60 kg, v₁ = your velocity after push = 3 m/s, m₂ = beau's mass = 45 kg and v₂ = beau's velocity.
So, m₁v₁ + m₂v₂ = 0
m₁v₁ = -m₂v₂
v₂ = -m₁v₁/m₂ = -60 kg × 3 m/s ÷ 45 kg = -4 m/s
So beau moves with a velocity of 4 m/s in the opposite direction
Answer:
0.5
Explanation:
The energy of a charged capacitor is given by 
where 
is the charge on it and 
is its capacitance. The capacitance is defined, geometrically, as
where 
is a constant that is determined by the material between the plates, 
is the area of the plates and 
is the distance between them. It is then that the capacitance is linearly inversely proportional to the separation distance; as the distance increases, the capacitance reduces.
Because it is linear, when the separation distance is doubled, other factors remaining constant, the capacitance is halved. Because the capacitance is halved, the energy is halved.
Let's see the mathematics.
Initial capacitance, 
at initial separation, 
If separation is doubled, separation becomes 
. Then the capacitance becomes
Initial energy, 
Final energy, 
Hence, 
Answer:
Running is probably the simplest individual sport for promoting both health-related and skill-related fitness. Fencing is often referred to as "mental chess" because it requires dexterity, endurance, and discipline. Individual sports require the coach to make all of the decisions for the athlete.
They're not hiding anywhere. They're all right there in the light that's shining into the mist.
It's just that when ALL the colors shine into your eye at the same time, your brain says "white".
