C) solid, liquid and gas phases
D) no phases are present at this point

Answers

The correct answer is A. The water at this conditions is in the solid phase. This can be verified by using a phase diagram. A phase diagram is a figure which shows the phases of a certain substance at a specific temperature and pressure.

Answer:

The answer is C) solid, liquid and gas phases

Explanation:

This point is called the triple point bc solid, liquid, and gas phases can exist together.

Assume you have 3 light bulbs connected in a series circuit to a battery.What can you say about the current through each light bulb?
Current varies through all bulbs
There is no current through the bulbs
Current is the same through all bulbs

Answers

Answer:

Current is the same through all bulbs

Explanation:

Because it's a series circuit, the current traveling through the circuit doesn't change. In a parallel circuit, however, the current would not be the same due to the different 'paths' of the circuit.

what is the force of gravity between a 1000000000 kg asteroid and the earth when the asteroid is 3000000 m away from the earth?

Answers

Mass of the Earth = 5.972 x 10²⁴ kg
Mass of the asteroid = 1 x 10⁹ kg
Separation distance = 3 x 10⁶ m (between the Earth's center and the asteroid's center)

Gravitational force between two masses =

(6.67 x 10⁻¹¹ nt-m²/kg²) · m₁ · m₂ / (distance)²

= (6.67 x 10⁻¹¹ nt-m²/kg²) · (5.972 x 10²⁴ kg) · (1 x 10⁹ kg) / (3 x 10⁶ m)²

= (6.67 · 5.972 / 9) x 10¹⁰ · (nt · m² · kg · kg / kg² · m²)

   = 13.28 x 10¹⁰ newtons

   =    132.8 Giga-newtons .
