Answer:
saddle weighs 250 newtons. The mass of the saddle is ____250/9.8 kg______ kilograms. Use g = 9.8 N/kg for gravity.
Answer:
The energy stored in the capacitor quadruples its original value.
Explanation:
The energy stored in a capacitor is given by the equation

where
C is the capacitance
V is the voltage across the plates
The capacitance, C, depends only on the properties of the capacitor, so it does not change when the voltage applied is changed.
Instead, in this problem the voltage applied is doubled:
V' = 2V
So the new energy stored is

so, the energy stored has quadrupled.
Answer:
24000 kg·m/s
Explanation:
Momentum is Mass x Velocity, so 1200 kg time 20 m/s = 24000 kg-ms/s
Neutral reaction is the reaction that occurs when an acid cancels with a base
First, you need forces attracting the Sun and Earth toward each other. That's described by Newton's law of universal gravitation.
Then you need the description of how that force causes the planet to move in a circular path. The best choice is Newton's <em>Second law</em> of motion: F = m A .
