What is the energy of a baby who weighs 20 N sitting on a 1.5 m high chair

1 answer:

3 0

The energy of the baby is gravitational potential energy, and it is equal to the weight of the baby times its height from the ground:
$U=(mg) h$
where
mg=20 N is the weight (the mass times the gravitational acceleration)
h=1.5 m is the height from the ground
If we plug the numbers into the equation, we find
$U=(mg)h=(20 N)(1.5 m)=30 J$

PLZ HELP ME The stored energy in organic matter or wastes is called biomass energy and when burned can be used to produce therma

Softa [21]

Answer:

True: The stored energy in organic matter or wastes is called biomass energy and when burned can be used to produce thermal energy used for cooking, heating homes or generating electricity.

Explanation:

For Household Needs, biomass is utilized for home heating or for cooking purposes. In that case the most common source for fuel is wood, but there are also other substances are used. Latest wood-stoves designs are made in an effective way for heating and cooking needs. With the help of those new technologies fuel consumption is decreased to a significant amount.

Humans have been using biomass energy since ages for cooking their food and heating homes by burning woods. Biomass energy can be used in homes for heating or cooking or in industries large power plants to produce electricity

What is Biomass Energy? Biomass consists of energy in stored form taken from the sun. In photosynthesis plants take energy from sun. By burning biomass the energy emitted in result can be used for heating purposes. There are many types of biomass energy made by either burning or by converting it into liquids or gas, called Bio-fuels and Bio-gas.

Summary:

No doubt Biomass contribute in air pollution formation but it is less than the pollution caused by certain gases and fossils fuels which produce sulfur resulting in acidic rain and polluting our environment.

Which of the following statements is false?

vladimir1956 [14]

An excited atom can return to its ground state by absorbing electromagnetic radiation is false about the electromagnetic radiation.

Option B

<u>Explanation</u>:

In the scope of modern quantum theory, the term Electromagnetic radiation is identified as the movement of photons through space. Almost all the sources of energy that we utilize today such as coal, oil, etc are a product of electromagnetic radiation which was absorbed from the sun millions of years ago.

Various properties of electromagnetic radiations are a directly proportional relationship between the energy and the frequency, Inverse proportionality between frequency and the wavelength, etc. Hence, we can conclude that an "excited atom" can never return to its ground state by assimilating electromagnetic radiation and the 2nd statement is false.
