Answer:
21.18 L
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 1 atm
Initial volume (V₁) = 18 L
Final pressure (P₂) = 0.85 atm
Final Volume (V₂) =?
With the application of the Boyle's law equation, we can obtain the final volume (i.e the new volume) of the gas as follow:
P₁V₁ = P₂V₂
1 × 18 = 0.85 × V₂
18 = 0.85 × V₂
Divide both side by 0.85
V₂ = 18 / 0.85
V₂ = 21.18 L
Therefore, the new volume of the gas will be 21.18 L
Answer:
149,700,000 km (= 1.50 x 10⁸ km)
Explanation:
Given,
Speed of light, c = 300,000 km/s
Time Taken = 8 min 19 s = 499 seconds
Recall, Distance = Speed x Time
= 300,000 km/s x 499 s
= 149,700,000 km
= 1.50 x 10⁸ km
What causes it to form: <span>Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Human activities, power plants, and exhaust from vehicles all are causes.</span>
Affects on living things-
Acid rain can kill trees
It can affect plant growth patterns
Toxins can kill animals
Nonliving things-
It can decay building materials and paints
it breaks down rocks

Answer:
(a) warm air is forced upward where it cools;
(c) cumulonimbus or nimbo-stratus clouds form
(d) thunderstorms with heavy showers and gusty winds occur"
(b) air cools and sinks, pressure rises, rain stops;
Explanation:
- A cold for front is a denser air , as that forms under the warmer and lighter air mass and this causes a low pressure along the cold form and thus causes the formation of a thunderstorm where enough moisture is present and drop in temperature occurs and in the northern hemisphere the cold front shifts the winds to from the southwest to northwest clockwise.
Answer:
The position x, is ± 0.4 m.
Explanation:
The total mechanical energy of the oscillatory motion is given as;
When the kinetic energy (E) is half of the elastic potential energy (U);
Equate (1) and (2)
Thus, the position x, is ± 0.4 m.
