A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

Solar energy
Nuclear energy
Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .

EXPLAIN WHAT DUAL ORGANISM MEANS

bagirrra123 [75]

Lichens have been described as "dual organisms<span>" because they are symbiotic associations between two (or sometimes more) entirely different types of microorganism - a fungus (termed the mycobiont) a green alga or a cyanobacterium (termed the photobiont).

The release of an inorganic phosphate from the myosin molecule directly results in ________

zhuklara [117]

Answer:

power stroke

Explanation:

The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.
