Answer:

Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an object, the object stays still or continues moving continues to move at the same speed and in the same direction.

The aluminum wire in a high-voltage transmission line is 2.7 cm in diameter. It is designed to carry a current of 1100 A. What i
marissa [1.9K]

Answer:

1660 V

Explanation:

Resistance should be determined and then voltage drop across the power line can be determined.

R = ρ L /A  

Here ρ = Resistivity of aluminum = 2.7\times 10^{-8}\Omega m

L = length = 32 km = 32,000 m

Area of cross section = A = π r² = π (0.027/2)² = 0.00057255 m²

Resistance = R =

(2.7\times 10^{-8}\Omega m (32,000)/(0.00057255) = 1.5090 Ohms.

Voltage drop = V = I R = (1100)(1.5090) = 1659.9 V.

(If resistivity value is different, then the resistance will be different and hence final answer for voltage will also vary ).

Which isotope has 16 neutrons and is used to study nucleotides and nucleic acids?
qaws [65]
When naming isotopes, the number beside it indicates the mass number. Now mass number is the sum of protons and neutrons. 

We know that the mass number of a stable Sulfur atom is 32, so  we can rule out C as an isotope. The atomic number of Sulfur is 16 and that means that there are 16 protons. Now if we subtract 16 from 33, then that means there are 17 neutrons. So we can rule out D. 

Phosphorus on the other hand has an atomic number of 15. If we subtract 15 from 31 we will have 16. That means that Phosphorus-31 has 16 neutrons.

The answer would then be A. Phosphorus 31.
