Superman throws a 2400 n boulder at an adversary. what horizontal force must superman apply to the boulder to give it a horizont
1 answer:
The horizontal force Superman must apply to throw the boulder is 3670N.
According to Newton's Second law of motion,
Force F = Mass m * Acceleration a
We know that Weight W = Mass m * Gravity g
Given,
Weight W = 2400 N
Acceleration a = 15 m/
Gravitational force g = 9.81 m/
W = m * g
Mass m = 2400 / 9.81 = 244.65 kg
Horizontal force F = 244.65 * 15 = 3669.7 N
Newton's Second law of motion states that acceleration of an object depends on force acting on the object and mass of the object.
Therefore the horizontal force Superman must apply to throw the boulder is 3670N.

Answer:
a) Differential mode gain = 48
b) Common mode gain = 0.4
c) CMRR = 120
Explanation:
The output of a difference amplifier is related to the input by the equation:
When V₁ = 6.4 V, V₂ = 5.1 V and V₀ = 64.7 V, the equation becomes
6.4 A₁ + 5.1 A₂ = 64.7.....................(1)
When V₁ = 5.6 V, V₂ = 4.9 V and V₀ = 35.7 V, the equation becomes
5.6 A₁ + 4.9 A₂ = 35.7.....................(2)
Multiply equation (1) by 5.6 and (2) by 6.4
35.84 A₁ + 28.56A₂ = 362.32.....................(3)
35.84 A₁ + 31.36 A₂ = 228.48....................................(4)
Subtract equation (3) from (4)
2.8 A₂ = -133.84
A₂ = -133.84/2.8
A₂ = -47.8
Put the value of A₂ into equation (1)
6.4 A₁ + 5.1 (-47.8) = 64.7
6.4 A₁ = 64.7 + 243.78
A₁ = 308.48/6.4
A₁ = 48.2
a) Common mode gain = A₁ + A₂ = 48.2 + (-47.8)
Common mode gain = 0.4
b) Differential mode gain = (A₁ -A₂)/2
Differential mode gain = (48.2 - (-47.8))/2
Differential mode gain = 96/2
Differential mode gain = 48
c) Common Mode Rejection Ratio (CMRR)
