I got this wrong because the person that answered this didnt even answer the question but puck 1 is going 12 m/s west
Answer:
32.087 m/s
Explanation:
Velocity Initial = 5.6 m/s
time= 2.7
acceleration = 9.81
Velocity final = ?
Vf = Vi + at
Vf = (5.6) + (9.81)(2.7)
Vf = 32.087 m/s
Answer:
Explanation:
Definition of the capacitance C, where a voltage V is applied and a charge Q is stored:
We solve to find V:
To solve this problem it is necessary to apply the concepts related to Pressure, Strength and Area.
We know by definition that Pressure is the amount of Force expressed per unit area, that is,
Where,
F = Force
A = Cross-sectional Area
The net pressure on the bottle would be given by the difference between the internal pressure and the atmospheric pressure, therefore
The given radio is,
Hence the Cross-sectional Area would be
Applying the equation for Pressure we have that
Therefore the frictional force on the cork due to the neck of the bottle is 429.66N.
