Answer:
Potential difference across resistor will be 87.66 volt
Explanation:
We have given number of electrons
Charge on one electron
So total charge
Time is given t = 5 min
1 minute = 60 sec
So 5 minute = 5×60 = 300 sec
So current
Resistance is given R = 40 ohm
Sp from ohm's law potential difference across resistor v = iR = 2.1866×40 = 87.466 volt
To minimize loss of heat or absorption of heat from surroundings
My answer is E. If am wrong then plz tell me whats the right
Interference if the hardest to remove due to the superposition of the frequencies of the radio waves
Answer:
0.52 m/s
Explanation:
Energy is conserved.
Initial kinetic energy + initial potential energy = final kinetic energy + final potential energy
½ m v₁² + ½ k x₁² = ½ m v₂² + ½ k x₂²
m v₁² + k x₁² = m v₂² + k x₂²
Given:
m = 1.3 kg
k = 52 N/m
v₁ = 0.28 m/s
x₁ = 0.081 m
x₂ = 0.081 m / 2 = 0.0405 m
(1.3) (0.28)² + (52) (0.081)² = (1.3) v² + (52) (0.0405)²
v = 0.52
The velocity halfway to the equilibrium position is 0.52 m/s.
