d. all of the above

Answers

Answer 1
Answer:

Little is known about much of earth’s early history because Precambrian rocks have been deeply buried they have been changed by heat and pressure ,Precambrian soft-bodied life-forms weren’t often preserved as fossils.

What is Precambrian rocks?

The Precambrian is the earliest part of Earth's history, set before the current Phanerozoic.

Why are Precambrian rocks rare?

Fossils are rare in Precambrian rocks mostly because Precambrian life-forms lacked bones, or other hard parts that commonly form fossils.

Hence, D is correct option

The transuranium synthesis process involves creating a transuranium element through ____.A.) The synthesis of heavy elements
B.) The transmutation of a lighter element
C.) The transmutation of uranium

Answers

The transuranium synthesis process involves creating a transuranium element through the transmutation of a lighter element. The answer is letter B. Transuranium elements are the elements with atomic numbers greater than 92. All of these elements are unstable and decay radioactively into other elements.

What causes light to bend when it moves from one transparent medium to another?a change in amplitude

a change in color

a change in frequency

a change in speed

Answers

Answer:

A change in speed

Explanation:

Light bends when it moves at a particular angle into a medium that has a different refractive index than the one it was coming from.

This bending is as a result of the change in speed of light as it enters the medium with a different refractive index.

This action is known as Refraction of light.

Refraction depends on the change in speed of light as it changes media and the angle of refraction depends on the angle of incidence of the ray of light and the refractive index of the material.
Whenever light goes from transparent to another medium or from rarer to denser medium or vice versa, it's speed changes and hence light bends.

Can a simple machine’s efficiency ever be greater than 100%?
Explain your answer.

Answers

100% efficiency is not possible, so any greater than 100% is also not possible. There is always some energy waste, normally through heat, sound, or light
Personally, I believe not. 100% is the total, and therefore, it cannot possibly be above 100% percent, as this wouldn't then mean that the machine is efficiently beyond its means
