Answer:
The equation of current is
Explanation:
Resistance, R = 12 ohm
Inductance, L = 0.06 H
E (t) = 12 cos (120 t)
Compare with the standard equation,
So, the inductive reactance is
XL = w L = 120 x 0.06 = 7.2 ohm
The impedance of the circuit is
The current leads by 90degree so the equation of current is
Answer:
a)F=3 x 10⁻⁷ N
b)x=2.405 m
Explanation:
Given that
m₁=295 kg
m₂=595 kg
d= 4.1 m
a)
m₃=63 kg
r=d/2 = 2.05 m
The force between the mass m₁ and m₃
by putting the values
F₁₃=2.94 x 10⁻⁷ N
The force between the mass m₂ and m₃
by putting the values
F₂₃=5.94 x 10⁻⁷ N
The net force F
F= F₂₃- F₁₃
F=5.94 x 10⁻⁷ N-2.94 x 10⁻⁷ N
F=3 x 10⁻⁷ N
b)
Lest take at distance x from mass m₂ net force is zero.
Form above two equation
x²=2.01(4.1-x)²
x=1.42 (4.1-x)
x=5.82 - 1.42x
x=2.405 m
Lets say a plant native to greenland is in canada (fossilized against canada's shore line) it's proof that at one moment they where actually connecting. <3
Impulse is the change in momentum
J = 1.5 kg(22 m/s - 15 m/s) = 10.5 kg-m/s
