Answer:
The answer is below
Explanation:
The resistance of a conductor (R) is given by:
and ρ is resistivity
The length = 20cm = 0.2 m
The tube has an outer diameter of 1.1 cm (0.011 m), hence the outer area is:
A₁ = π * diameter²/4 = π * 1.1²/4 = 0.000095 m²
The tube has an inner diameter of 0.85 cm (0.0085 m), hence the inner area is:
A₂ = π * diameter²/4 = π * 0.0085²/4 = 0.0000567 m²
The conductor area = outer area - inner area = 0.000095 m² - 0.0000567 m² = 0.0000383 m²
Hence, the resistance is:
Deceleration isn't a term in physics; you can have positive acceleration which is speeding up and negative acceleration which is slowing down
Use newton's law F = ma
a = F/m
The at the top, the higher something is the more potential energy it has because if both fall the one at the top will have more kinetic energy
It's 35 degrees IF they have the same declination. If their declinations are different, then the angle between them can be anything from 35 degrees to 180 degrees.
