Answer:
10 N, 
north-east
Explanation:
The two forces applied on the object are perpendicular to each other, so we can find the magnitude of their resultant by using the Pythagorean theorem:
The direction of the force instead is given by
where F_n is the force pointing north, and F_e is the force pointing east, and the angle is measured with respect to the east direction. Substituting,
Answer:
1. is A. a calung
2. is A. Kayuthin
3. is B. Gendang
4. is D Slendro
5. is D Singapore Symphony Orchestra
Explanation:
Next time space them out, have a nice day baby face :D
Answer:
The correct answer is combustibility
Explanation:
A chemical property of a matter is a property in which a matter has the tendency to change its form through chemical reaction(s).
A matter is said to have combustibility property if it can undergo combustion. Combustion is a chemical process in which a substance burns in excess oxygen to produce carbon dioxide and water.
Consider the equation below
CH₄ + O₂ ⇒ CO₂ + H₂O
The equation above shows methane burning in excess oxygen to produce carbon dioxide and water
Answer:
Barometer is an instrument used to measure the atmospheric pressure.
Explanation:
- Torricelli did an experiment by filling a one meter long test tube completely with mercury. He took a beaker with some amount of mercury in it and inverted the test tube filled with mercury by closing its open end into the mercury of beaker ensuring that no bubble is trapped into the mercury of test tube during the process.
- This experiment was performed at normal temperature and pressure. Now some of the mercury from the test tube fell down into the beaker through the open end until the level becomes stagnant and this denotes the atmospheric pressure in terms of mercury column.
- There was a vacuum created at the top of the test tube called torricellian vacuum which holds back the remaining mercury height and the rest of the mercury level in the beaker is facing the atmospheric pressure.
