3 0

Answer:

0.024m/s

Explanation:

Firstly, we have to convert the 3.20cm/s to m/s which is done by dividing the 3.20 by 100. the answer gives 0.032m/s. Then using the formular v=c/n where v is the apparent speed, c = speed of object and n is the refractive index of medium.we can now solve using the above formular which is 0.032m/s/1.333 = 0.024m/s

Starter

Explanation:

Turn the ignition switch to start and release the key immediately or you could destroy the starter.

The car starter is used to cause ignition in the internal combustion engine in order to fire the piston and cause mechanical motion. The starter is used to start the cyclic process of the internal combustion engine.

  • Once the engine starts by igniting the starter, it is best to release it.
  • The starter ensures that the spark plug is engaged and the motor is brought into work.
  • If the ignition is still engaged, the process continues repeatedly and it can damage the starter of the car.

Minchanka [31]

Answer: The energy absorbed by the reaction from the water is 996 Joules.

Explanation:

Energy absorbed by the reaction or energy lost by the water to the reaction,Q.

Mass of the the reaction  ,m = 60 g

Specific heat of water = c = 4.15 J\g ^oC

Change is temperature=\Delta T=19^oC-23^oC=-4^oC

Q=mc\Delta T=60 g\times 4.15 J\g ^oC\times (-4^oC)=-996 Joules

Negative sigh indicates that energy was given by the water to the reaction.

The energy absorbed by the reaction from the water is 996 Joules.
