A blender transforms M energy into K energy. What do M and K most likely represent?
Trava [24]

D. M represents electrical energy, K represents mechanical energy

Explanation:

A blender transforms electrical energy to mechanical energy. Where M is the electrical energy and K is the mechanical energy.

  • A blender is laboratory device used to mix and puree food substances especially fruits.
  • It is powered by electricity which causes the blades to turn and rotate very fast.
  • therefore, it transforms electrical energy into mechanical energy.

The individual dipole moments in ammonia (NH3) do not cancel each other
kozerog [31]

Answer:

                    The strongest force that exists between molecules of Ammonia is <em>Hydrogen Bonding</em>.

Explanation:

                    Hydrogen Bond Interactions are those interactions which are formed between a partial positive hydrogen atom bonded directly to most electronegative atoms (i.e. F, O and N) of one molecule interacts with the partial negative most electronegative atom of another molecule.

                    Hence, in ammonia the nitrogen atom being more electronegative element than Hydrogen will be having partial negative charge and making the hydrogen atom partial positive. Therefore, the attraction between these partials charges will be the main force of interaction between ammonia molecules.

                  Other than Hydrogen bonding interactions ammonia will also experience dipole-dipole attraction and London dispersion forces.

The pressure in a car tire is 178 kPa at 37°C. After a long drive, the pressure is 275 kPa. What is
dimaraw [331]

Answer:

T₂ = 478.93 K

Explanation:

Given that,

Initial pressure, P₁ = 178 kPa

Initial temperature, T₁ = 37°C = 310 K

Final pressure, P₂ = 275 kPa

We need to find the new temp of the air in the tire, assuming the volume is constant. We know that,

\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{275\times 310}{178}\\\\T_2=478.93 K

So, the new temperature is equal to 478.93 K.
