Answer:
Explanation:
Comet is made by dust particles, icy particles, gases etc.
A comet has a fixed time to complete a revolution around the sun.
As a comet comes nearer to the sun, due to the heat of the sun the vapour and the icy particles becomes gases and due to the radial pressure of energy od sun, we observe a tail of comet which has vapours mainly. SI the comet is visible easily.
Answer:
Electrostatic force is force between two charges separated by distance in space while gravitational force is the force between two masses separated by a distance. Electrostatic force is either repulsive or attractive while gravitational force is always attractive
Explanation:
the answer to you question is D.
They are chemically opposite in that the reactants of one are the products of the other. One could not exist without the other to supply the materials.
You can look up the reactants and products in any Biology textbook. also <span>In Photosynthesis carbon dioxide and energy is consumed to give sugar and Oxygen. </span>
<span>while in Respiration oxygen and sugar is consumed to give energy and carbon dioxide is produced. </span>
<span>Hence the two are opposite of each other. </span>
<span>Now, since you need oxygen to respire there must be a constant supply of oxygen and plants are the source of oxygen since they produce oxygen due to photosynthesis, similarly plants need oxygen to do photosynthesis which is produced by respiration. </span>
<span>Hence they both are dependent on each other HOPE IT HELP ;D</span>
