Answer:the 90% is spent performing other functions
Explanation:
Answer:

Explanation:
The capacitance of the parallel-plate capacitor is given by:

where
is the vacuum permittivity
is the area of the plates
is the separation between the plates
Substituting,

The energy stored in the capacitor is given by

Since we know the energy

we can re-arrange the formula to find the charge, Q:

A lab cart is loaded with different masses and moved at various constant velocities? the anser should be
1.0m/s → 4kg
The refractive index for glycerine is

, while for air it is

.
When the light travels from a medium with greater refractive index to a medium with lower refractive index, there is a critical angle over which there is no refraction, but all the light is reflected. This critical angle is given by:

where n1 and n2 are the refractive indices of the two mediums. If we susbtitute the refractive index of glycerine and air in the formula, we find the critical angle for this case:
Answer:
Net displacement = 0
Distance traveled = 2PQ <_up and down
