Can anyone help me with this

There are four laws of thermodynamics.

Zeroeth Law of Thermodynamics: Two systems in thermal equilibrium with a third system are in thermal equilibrium to each other.

First Law of Thermodynamics: The change in a system's internal energy is equal to the difference between heat added to the system from its surroundings and work done by the system on its surroundings.

Second Law of Thermodynamics: It is impossible for a process to have as its sole result the transfer of heat from a cooler body to a hotter one.

Third Law of Thermodynamics: The entropy of a perfect crystal at absolute zero is exactly equal to zero.

A moving object has a kinetic energy of 150J and a momentum of 20.3kgxm/s find the speed of the object in m/s
Irina-Kira [14]

Answer:

v = 14.78m/s

Explanation:

Given

KE = 150J

p = 20.3kgm/s

Required

Determine the object's speed

Kinetic Energy is calculated as:

KE = \frac{1}{2}mv^2

Make m the subject

m = \frac{2KE}{v^2}

Momentum is calculated as:

p = mv

Make m the subject

m = \frac{p}{v}

So, we have:

m = \frac{p}{v} and m = \frac{2KE}{v^2}

Equate both expressions: m = m

\frac{2KE}{v^2} = \frac{p}{v}

Multiply both sides by v

v *  \frac{2KE}{v^2} = \frac{p}{v}*v

\frac{2KE}{v} = p

Make v the subject

v = \frac{2KE}{p}

Substitute KE = 150J and p = 20.3kgm/s

v = \frac{2 * 150}{20.3}

v = \frac{300}{20.3}

v = 14.78m/s

Larger size, longer life, and specialization are three advantages to<br> being a
Ivanshal [37]

Answer: Multicellular organism

Explanation:

Multicellular organisms refer to living things that have more than a single cell as opposed to unicellular organisms such as bacteria. Humans as well as all animals and land plants fall under this classification.

Multicellular organisms can live longer because new cells can be produced when others die. They are also larger due to the presence of many different cells which then specialize in different roles to ensure the survival of the organism.
