Answer:
Newton's second law
Explanation:
Mathematically, Newton's second law can be written as
where
F is the net force on the particle
m is its mass
a is the acceleration
This can also be rewritten as
which means that the acceleration is directly proportional to the force and inversely proportional to the mass. If the net force is non-zero, it means that the particle has a non-zero acceleration, therefore its velocity is changing (it can be changing either in magnitude, if the force has same direction as the velocity, or also in direction, if the force has a different direction).
Answer:
The angular displacement of each wheel is 269.92 rad
Explanation:
Given:
Angular acceleration
Time to pass cyclist s
Angular velocity
According to the equation of kinematics,
For finding angular displacement,
Where angular displacement,
rad
Therefore, the angular displacement of each wheel is 269.92 rad

Answer:
Explanation:
Area of electrodes, A = 2 cm x 2 cm = 4 cm²
Separation between electrodes, d = 1 mm
Voltage, V = 9 V
(a)
Let C is the capacitance between the electrodes
C = 3.54 x 10^-12 F
Let q be the charge on each of the electrode
q = C x V
q = 3.54 x 10^-12 x 9 = 3.2 x 10^-11 C
(b)
As, the battery is disconnected the charge on the electrodes remains same.
(c)
As the battery is connected the voltage is same.
capacitance is change.
As the distance is doubled, the capacitance becomes half and the charge is also halved. q' = q/2 = 1.6 x 10^-11 C
