An example of an energy transformation from nuclear to electromagnetic is: The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.

Explanation: The change of energy from one form to another is known as energy transformation. In every second energy transformations is constantly occurring everyplace.

Energy is transferable but it cannot be generated or destroyed. Electrical, mechanical, electromagnetic, nuclear, and chemical are some forms of energy.

The energy stored in the nucleus of an atom is known as Nuclear energy. Huge amounts of energy gets released at the time when nuclei combines or breaks. The gravitational collapse of hydrogen clouds produce heat and pressure that helps in activating Nuclear Fusion.

Calculate the density 1.33*10⁻⁷ gcm⁻³ into kgm⁻³.
Alex Ar [27]

1 Kg = 1,000g

Therefore 1.33 × 10^-7 g = 1.33 × 10^-10 kg

1m³ = 1,000,000cm³

Therefore 1 cm³ = 1 × 10^-6 m³

Dividing the mass per unit volume you get:

(1.33 × 10^-10 kg) ÷ (1 × 10^-6 m³)

= 1.33 × 10^(-10--6) = 1.33 × 10^(-10 + 6) = 1.33 × 10^-4 kg/m³

Density = 1.33 × 10^-4 kg/m³

As an interstellar cloud of hydrogen gas shrinks in size, its rate of rotation
FinnZ [79.3K]

Answer:

INCREASES, BECAUSE ITS ANGULAR MOMENTUM IS CONSERVED.

Explanation: Interstellar cloud of Hydrogen is an accumulation of Hydrogen gas in the cloud.

As the Interstellar cloud of Hydrogen shrinks (reduces) in size,the rate of rotation of the shrinked Interstellar cloud Increases because its angular momentum is conserved. GASEOUS MOLECULES MAKE UP ABOUT 99% OF THE INTERSTELLAR CLOUD WITH HYDROGEN HAVING ABOUT 90% OF THE VOLUME OF GASES IN THE INTERSTELLAR CLOUD.

Use this free body diagram to help you find the magnitude of the force F2 needed to keep this block in static equilibrium. WILL
oksian1 [2.3K]
Static equilibrium means that all forces are equal, so make this easiest you want to break F1 into it's horizontal and vertical components. As there are no other forces acting in the horizontal, we know the horizontal component of F1 is 40N. This allows the vertical component to be found using pythagorus theorem. After finding the vertical and horizontal components, you just have to add the vertical components to find the difference between the up and down.
