At what point in a projectile’s trajectory does it experience a minimum velocity?

Physics
1 answer:
ad-work [718]3 years ago
8 0
Minimum velocity occurs at the top of the trajectory, where
the projectile stops rising and starts falling.  For a split second,
it has no vertical speed at all, and its velocity is only the horizontal
speed (which doesn't change).

What happens to the temperature during an endothermic reaction? ANSWERS; The temperature stays constant. The temperature will de
EleoNora [17]

Answer:

The temperature will decrease (get colder).

Explanation:

Enthalpy changes are heat changes accompanying physical and chemical changes. The enthalpy change is the difference between the sum of the heat contents of products and the sum of heat contents of reactants.

  • For an endothermic change, heat is absorbed for the reaction.
  • The surrounding becomes colder at the end of the reaction and so is the reaction itself.
  • The right choice is that the temperature will decrease.

What is the percent increase in the vapor pressure of water when the temperature increases by 1 °c from 14°c to 15°c.
Artemon [7]

The Vapor Pressure of water increases by 5.1%.  when the temperature increases by 1 °c from 14°c to 15°c.

The vapor pressure of a liquid, sometimes referred to as the equilibrium pressure of a vapor above its liquid, is the pressure of the vapor produced by the evaporation of a fluid (or solid) over a sample of the liquid (or solid) in such a closed container (or solid).

Vapor pressure is the term for the force that is produced as liquids evaporate. Three factors commonly have an effect on a vapor press: surface area, intermolecular forces, and temperature. The vapor pressures of molecules change with temperature.
