Answer:

A compressed spring

Explanation:

A compressed spring has potential energy only and no kinetic energy.

This is because kinetic energy is only possessed by particles in motion.

Energy in a compressed spring= -1/2kx² where x is the displacement.

In this equation there is no velocity so there is no kinetic energy.

Answer:

A compressed spring

Explanation:

Option C is correct. The potential energy is the energy stored in a compressed spring. This potential energy depends on the spring constant and the distance traveled by the spring as it is stretched. The work that is done in stretching a spring gets stored in the compressed spring as potential energy.

Option A is incorrect. As sound wave is a mechanical wave that carries both potential and kinetic energy.  

Option B is incorrect. Arrow shot from a bow has kinetic energy.  

Option D is incorrect. A vibrating atom has vibrational energy.

What is the basic definition of carbohydrates
ikadub [295]

Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.

Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.  

Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain  three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.

A 100g sample of Carbon-14 has a half-life of 5 years. How much Carbon-14 is left after 10 years?
attashe74 [19]

Answer: The amount of carbon-14 left after 10 years is 25 g

Explanation:

Formula used :

a=\frac{a_o}{2^n}

where,

a = amount of reactant left after n-half lives = ?

a_o = Initial amount of the reactant = 100 g

n = number of half lives =\frac{\text {given time}}{\text {half life}}=\frac{10}{5}=2

Putting values in above equation, we get:

a=\frac{100g}{2^2}

a=\frac{100g}{4}=25g

Therefore, the amount of carbon-14 left after 10 years is 25 g
