The list of options to answer this question is:

A.kinectic energy is transformed into thermal energy.

B.electrical energy is transformed into potential energy.

C.potential energy is transformed into kinectic energy.

D.mechanical energy is transformed into chemical energy.

The answer is the option A. A.kinectic energy is transformed into thermal energy.

As you know energy cannot be lost but transformed.

When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.

Suppose Earth was tilted much less on its axis. What effect would this have on the planet? Please help me !
hodyreva [135]

Answer:

If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.

Explanation:

If a planet tilts more, it leads to colder winters and warmer summers. However, if a planet tilts less, it leads to less severe seasons that is and milder winters and cooler summers.

If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.

Which solution is most dilute?
olga55 [171]

C. 0.1 M HCl

Explanation:

The solution with the lowest molarity is the most dilute of all.

This is why the choice is 0.1M of HCl.

Molarity is the same as concentration. The unit "M" denotes mole per liter volume of solution.

  • Molarity is defined as the number of moles of solute in a give volume of solution.
  • 0.1M means 0.1mole of HCl is dissolved in 1liter of solvent.
  • The higher the number of moles dissolved and the more the concentration of the solution will be.

The order of increasing concentration is:

  0.1M < 0.2M< 0.3M < 0.4M
