Answer:
- The equivalent capacitance of the combination is greater than the capacitance of either of the capacitors.
- The voltage across each of the capacitors is the same.
- The sum of the charge stored on each capacitor is equal to the charge supplied by the battery.
Explanation:
The capacitance connected in parallel will have the same potentials across its ends. If the battery has a charge Q, it is divided among the capacitors.
That is,
Q = q₁ + q₂ + q₃
But, the potential is shared equally as V. So, the individual capacitance of the equation has the form q₁ = C₁V , q₂ = C₂V, etc.
So, in this case, when the effective capacitance is formulated, it would be
C = C₁ + C₂ + C₃ farad
Therefore, the true statements are
The equivalent capacitance of the combination is greater than the capacitance of either of the capacitors.
The potential across each of the capacitors is the same.
The charge supplied by the battery divided among the capacitors.
<h2>
The car tire makes 149 revolutions before coming to stop.</h2>
Explanation:
a) We have equation of motion v² = u² + 2as
Initial velocity, u = 32.4 m/s
Acceleration, a = -1.70 m/s²
Final velocity, v = 0 m/s
Substituting
v² = u² + 2as
0² = 32.4² + 2 x -1.70 x s
s = 308.75 m
Distance traveled before stopping is 308.75 m
Radius of tire = 0.330 m
Circumference of tire = 2πx 0.33 = 2.07 m
1 revolution = 2.07 m
The car tire makes 149 revolutions before coming to stop.
Answer:
speed of masses after collision = 2m/s
Explanation:
Using the formula for inelastic collision;
m1u1 + m2u2 = (m1+m2)v
Where m1 is mass of body 1
m2 is mass of body 2
u1 is initial velocity of body 1
u2 is initial velocity of body 2
v is final velocity
m1 =2kg , u1=5m/s , m2=3kg, u2=0(body at rest) v=?
(2*5) + (3*0)= (2+3)v
10=5v
v = 10/5
v=2m/s
