The time taken by the swimmer was 1 hour.
Why?
Since the swimmer is maintaining an angle of 150° while he was swimming, there were two components of the speed (horizontal and vertical). If we want to calculate the time taken by him to cross the river, we need to calculate the vertical speed and consider that the flow's speed is compensated by his horizontal speed.
We can calculate both components of the speed using the following formula:
Now, calculating we have:
Therefore, we have that the horizontal speed is compesating the flow's speed while his vertical speed is used to cross the river which is 1 Km wide.
Hence, we have that the tame taken is:
Have a nice day!
Answer:
Galaxy > The solar system > The sun > The earth
Explanation:
A galaxy is usually defined as a large accumulation of interstellar dust and gas particles, and also includes many solar systems, the sun, the planets, and other rocky planets. The name of the galaxy comprising the earth and the sun is the Milky way galaxy. The milky way galaxy has a diameter ranging between 150,000 and 200,000 light-years.
The solar system is composed of the nine planets including the asteroid belt, that goes around the sun in different orbits. The size of the Solar System is about 287.46 billion km in terms of diameter.
The sun is located at the central portion of the solar system that is the main source of energy. Its size is roughly 695,510 km in terms of diameter.
The earth is the only planet where life exists and is the 3rd planet that is closer to the sun, having a diameter of approximately 12,742 km.
