Which of the following is not true about the sun

skelet666 [1.2K]

Answer:

"The Sun's diameter is about five times that of Earth" is not true about the sun.

Explanation:

The Sun at the pivotal of the solar system is a star and covers 99.86% of the total mass of the system. Approximately 73% mass of the sun is due to hydrogen gas while nearly 25% mass due to helium and for the remaining mass small amount of heavier elements like carbon, oxygen, neon and iron are responsible.

The diameter of the sun is 864,000 miles or 1.39 million km or 109 times of the Earth while mass is 330,000 times of the Earth's mass. Sun is a almost perfect sphere of hot plasma with internal convective motion responsible for production of a magnetic field through a dynamo process. And the most important source of energy on Earth for life.

Which source of power can reduce emission of carbon dioxide?

ki77a [65]

Answer:

wind

Explanation:

this is because the others when burnt releases large amounts of carbon of carbon dioxide as they are carbon based and oxidises when burnt. However wind is renewable and converts the kinetic energy in the wind to electrical energy by the use of a turbine

You are riding on a carousel that is rotating at a constant 24 rpm. It has an inside radius of 4 ftand outside radius of 12 ft.

Nookie1986 [14]

Answer:

magnitude of the Coriolis acceleration is 44.235 ft/s² and the direction of the acceleration is along the axis of transmission

Explanation:

Given the data in the question;

Speed of carousel N = 24 rpm

From the diagram below, selected path direction defines the Axis of slip.

Hence, The Coriolis is acting along the axis of transmission

Now, we determine the angular speed ω of the carousel.

ω = 2πN / 60

we substitute in the value of N

ω = (2π × 24) / 60

ω = 2.5133 rad/s

Next, we convert the given velocity from mph to ft/s

we know that; 1 mph = 1.4667 ft/s

$V_{slip$ = 6 mph = ( 6 × 1.4667 ) = 8.8002 ft/s

Now, we determine the magnitude of the Coriolis acceleration

$a_c$ = 2( $V_{slip$ × ω )

we substitute

$a_c$ = 2( 8.8002 ft/s × 2.5133 rad/s )

$a_c$ = 44.235 ft/s²

Hence, magnitude of the Coriolis acceleration is 44.235 ft/s² and the direction of the acceleration is along the axis of transmission
