The voltage provided by the power supply = 20 V
<h3>Resistors in series </h3>
The Voltage across resistors in series in a circuit is equal to the sum of the voltage drops across each resistor.
Therefore for two resistors in series the total voltage provided by the power supply is equivalent to the summation of the voltage drops acroos each resistor ( i.e 10 V + 10 V = 20 V )
Hence we can conclude that the voltage provided by the power supply is 20 V

The product of (wavelength) times (frequency) is always the same number ...
the speed of the wave in whatever material it's traveling through. So if the
frequency is increased, then the wavelength must <em><u>de</u></em>crease by the same
factor, in order to keep the product the same.
Answer
given,
mass of the gate = 4.5 kg
distance between the hinge 1.5 m
mass of the bird = 1.1 kg
velocity of the bird = 5 m/s
a) from conservation of angular momentum
b) There is no external torque hence, momentum is conserved
initial kinetic energy =
initial kinetic energy =
= 13.75 J
final kinetic energy
KE =
KE =
KE = 7.14 J
Kinetic energy is not conserved
hence, the collision is inelastic.
Work Done = Force * Distance
This means the least work is exerted by the most distance, so the longer ones are less likely to break.
The shortest one will be the one that breaks easiest.
Magnitude is basically the measurement,
distance is the total ground that you covered. If you started at point a, walked ten feet to point b, then turned around and walked 13 feet to point c, your total distance would be 10 + 13 = 23 feet
using the same example, your displacement is only how far away you are from the starting point. So point b doesnt matter, because you end up passing through point a again (I hope that made sense :o) and the magnitude of your displacement would be 3 feet
