Answer:
1.77 N
Explanation:
Mass of bullet m = 1.7 x 10⁻³ kg
velocity v = 380 m /s .
Momentum of one bullet
= 1.7 x 10⁻³ x 380
= 646 x 10⁻³ kg m/s
momentum of 165 bullets
= 165 x 646 x 10⁻³ kg m/s
= 106.59 kg m/s
Final momentum after bouncing
= 0
change in momentum
= 106.59 - 0
= 106.59 kg m/s
This change occurs in one minute
so rate of change in momentum
= 106.59 / 60 kg m/s per second
= 1.77 kg m/s per second
rate of change in momentum = force
This is force on superman's chest
Force required = 1.77 N .

Answer:
capacitance of the capacitor = 0.18 μ F
Explanation:
Area of the plate A = 0.063 m x 5.4 m = 0.3402 m²
distance between the plate d = 3.5 × 10–5 m
dielectric value for Teflon K = 2.1
capacitance of capacitor = ?
Formula for capacitance of parallel plate is as follows ,
(Where 
)
putting the values in the equation,
C = 
=0.18 μ F
