Answer:
The x and y components of the 500 N-force are 321.394 newtons and 383.023 newtons, respectively.
Explanation:
At first we present a figure describing the situation explained on statement, the x and y components of the force are determined by the following trigonometric expressions:
(1)
(2)
Where:
- Magnitude of the force, measured in newtons.
- Direction of the force above the horizontal surface, measured in sexagesimal degrees.
If we know that 
and 
, then the components of the force is:
The x and y components of the 500 N-force are 321.394 newtons and 383.023 newtons, respectively.
The answer is C. Flammability because if you were to test flammability of an object, you would e making a chemical change to the object.
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
a plasma is a hot ionized gas consisting of equal numbers and positively charged ions and negativly charged electrons. the characterisitcs of plasma are different from those of oirdinary gases so plama is consideres the fourth state of matter
<h2>Movement of Continents</h2>
Explanation:
- Alfred Wegener was a German astronomer who proposed the "continental drift" hypothesis in 1910.
- Alfred Wegener was not able to explain the movements of the continent in how and in which way they are moved.
- He failed in an attempt to explain with the use of tides made the theory undefinable fully.
- Also, the major problem with Wegener's theory of Continental Drift was that there was no proper explanation of a mechanism.
