Answer:
Explanation:
Gravity is force of attraction between bodies that have masses. It is one of the most importance force in the universe that keeps it in an ordered form.
From what is obtainable from newtons law of universal gravitation, which states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them";
we know that;
- Gravity is a force of attraction that pulls objects toward the earth's center.
- It increases with mass between two objects
- It decreases as the distance increases
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:
Resistivity Method
Explanation:
A disadvantage of some geophysical techniques based on magnetism is that their use in urban areas may be subject to distortion resulting from power lines and metals in the immediate vicinity. One method that can be used in such areas relies on soil moisture and the ground's resistance to electricity and is known as Resistivity.
It is usually carried out by injecting a small electrical current through the earth and measured a subtle sub-surface change in resistance over a given area.
Answer:
North and east are at 90 degree, equation becomes
Explanation:
(2x 2)+[2(x+5)] 2=50 2
on solving, we get
x=12.366km/h
