Answer:

The measurement of the force it takes to work against gravity is called weight. You can measure weight on a scale. If you try to pick up heavy objects, you might need to be as strong as a super hero to lift them. Lifting overcomes the pull of gravity. Heavier objects need to have a strong force to lift them.

Small birds can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate. (Figure 1) F

Katen [24]

Answer: 3.1107grams of fat.

Explanation:The speed to cover 800 km in 20 hours will be 40km/hr, Because

Speed =Distance/Time.

This is equal to 72,000 seconds. At a power consumption of 1.7 W, the bird will consume (1.7 X 72,000) =122,400 J of energy.

A gram of fat contains about (9.4 Calories X 4186 J/Calorie) ,=39348 joules of energy, the bird will need (122,400 / 39,348) = 3.1107 grams of fat.

Answer:

The number of grains of sand on all the beaches on Earth

Explanation:

if we assume grain of sand has an average size , then the number of grains of sand on all the beaches on Earth is roughly $7.5 \times 10^{18}$

The total number of stars in the observable universe is roughly equivalent to 1 billion trillion. which is roughly equal to the number of grains of sand on all the beaches on Earth.

<h3 /><h3>What is the solar system?</h3>

The satellites of the planet, countless comets, asteroids, and meteoroids, as well as the interplanetary medium, make up the solar system.

The complete question is;

"Choose the correct star life cycle.

A. Supernova, star as well as red giant, the nebula is incorrect.

B. Nebula, white dwarf, planetary nebula That is incorrect.

C. Planetary nebula, red giant, white dwarf, and star with a single stellar mass That is true!

D. Nebula, a star of one stellar mass, is not correct. It is correct if the star had four or more stellar masses."

Star of one stellar mass, red giant, white dwarf, and planetary nebula make up the proper life cycle.

Hence option C is correct.
