How long would it take for a rock falling 97.2 m/s to reach the ground from 100 meters
mote1985 [20]

Answer;

velocity(v) = 97.2 m/s ,

distance (S) = 100 m

determine time(t) = ?

  We know that,

               distance (S) = velocity(v) × time(t)

           So,      time (t) = distance ÷ velocity

                                   = 100 ÷ 97.2

                              <em>   t = 1.02 sec.</em>

<em>I hope this will help you.</em>

(NH4)2CO3(s) ⇄ 2NH3(g) + CO2(g) + H2O (g)

The  effect  that adding  water (H2O)   have in reaction above is  that The  concentration of the product  would  decrease, and the concentration of reactant  would increase. (answer  C)


   <u><em>Explanation</em></u>

  •  If the  concentration   of one substance is changed, the equilibrium  shift to minimize  the effect of that change.
  • H2O   in reaction above  is  a product.

  • Increase of water (H2O)  concentration will led to the shift of equilibrium  to the left ( reactant  side)  .The concentration of  reactant  increase  as that of product decrease.

If a Mack truck and Honda Civic have a head-on collision, upon which vehicle is the impact force greater?
goblinko [34]

Answer:

Honda Civic

Explanation:

As per the structural design and purpose of use for vehicle, Both are different from one another in various terms such as size, strength and design.

Mack trucks are very huge trucks especially designed for loading heavy objects. They are even used to carry heavy consignments such as cars.

Whereas Honda civic has a sleek structural design and have a very fragile body as it is sedan car, so if there will be a head-on collision between these two vehicles, certainly there will be a huge impact force on civic and it will even smash into pieces if any of the vehicle have high speed.
