Answer:
Explanation:
In a reversible reaction which has reached dynamic equilibrium , rate of forward reaction is equal to rate of backward reaction .
Following is a reversible chemical reaction .
A + B = C + D
Rate of forward reaction = k₁ x [ A ] x [ B ]
Rate of backward reaction = k₂ x [ C ] x [ D ]
k₁ x [ A ] x [ B ] = k₂ x [ C ] x [ D ]
[ A ] x [ B ] = k₂ / k₁ [ C ] x [ D ]
[ A ] x [ B ] = k [ C ] x [ D ]
The products of the forward and backward reactions remain
constant at equilibrium.
Hence option A and D are correct statement .
(a)to find voltage of battery we use the wire containg 4 ohm resistor and 3 ohm resistor
the voltage of 4ohm = Ri=4x1.5=6V
the voltage of 3 ohm = Ri=3x1.5=4.5v
since voltage is additive in series then Voltage of batteries = 4.5+6=10.5V
(b) the currrent flowing in 20 ohm resistor is the same as 8 ohm resistor so
Voltage of 8 ohm + voltage of 20 ohm= 10.5
8i+20i=10.5
28i=10.5
i=0.375 A

Answer:
a. Horizontal component v = 12 m/s
b. Magnitude of velocity v = 20.78 m / s
Explanation:
Vₓ = 12.0 m / s eastward
β = 30.0 °
So
a.
Vt = Vₐ - Vₓ
Vₐ = 0 i
Vt = 0i - 12.0 = - 12 m/s
b.
Vₙ = 12 / sin (30 °)
Vₙ = 24 m / s
Vₙ = 24 * con (30 °)
Vₙ = 20.78 m / s
Answer:
Part a)
Part b)
Explanation:
Let the length of the rod at 0 degree Celsius is given as Lo
now we have
now we know that
= Length of rod at zero degree C
Part a)
now we have
now we have
Part b)
length of the rod is 6.3689 cm
now we have
