Explanation

The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

• The nucleus of an atom contains protons and neutrons.
• The nucleus is the central part of an atom.
• Protons have a positive charge.
• Neutrons have no electric charge.
• Electrons are found outside the nucleus
• The nucleus makes up much less than. 01% of the volume of the atom,
• But typically contains more than 99.9% of the mass of the atom.

Explanation

The number of bones in a human skull is 22

The human skull is generally considered to consist of twenty-two bones

• eight cranial bones
• fourteen facial skeleton bones

**

while

300 bones are there in a newborn infant.

The human hand has 27 bones

Explanation

Optical disk drives (like CD, DVD, and Blu-ray drives) use laser technology to read and write data on optical discs.

The laser beam detects the pits and lands on the disc surface to interpret data.

Explanation

Horses have a unique anatomy and a stay apparatus

That allows them to sleep standing up, but they lack the anatomical structure (a proper “down apparatus”) to sit like dogs or cats. 

Explanation

 Uranium is not a fossil fuel; Coal and Oil are. 

Fossil fuels are formed from the remains of decomposed organic matter (plants and animals) over millions of years.

Uranium, a radioactive element, is not formed from organic matter and is considered a nuclear fuel, not a fossil fuel

Explanation

The animal that uses echolocation for movement is the bat. 

Bats use high-frequency sound waves to navigate

And find food in the dark by emitting sounds

And then listening to the echoes that bounce back off objects. 

Explanation

Asteroids are also called "minor planets".

They are small, rocky bodies that orbit the Sun, often between Mars and Jupiter.

They are considered remnants from the formation of the solar system and are not large enough to be classified as a planet. 

"asteroids" (possibly what "altereds" was meant to be)

Explanation

Two or more forces acting on the same point at the same. time are called concurrent forces.

While

A concurrent coplanar force system is a system of two or more forces whose lines of action intersect at a common point.

Explanation

When an elevator accelerates downward, the normal force (apparent weight) decreases.

Thus, the person feels lighter than their actual weight.
