Explanation:
The law of effect given by Edward Thorndike explains the behavior of child given in the problem . The effect which gives pleasure and satisfying effect are likely to be learnt easily and the effect which creates bad taste are likely to be forgotten easily . actions producing feel good effect are likely to be repeated in future .
The green house gases can be reduced up to a limit by eliminating the fossil fuels and chlorofluorocarbons. Fossil fuels are the major source of greenhouse gases.
<h3>What are green house gases?</h3>
Greenhouse gases are those which are capable of intense absorption of the temperature radiated from the earth's surface and make the earth atmosphere warm up.
Greenhouse gases are the main cause of global warming. Carbon dioxide, methane oxides of nitrogen and sulphur are the green house gases.
Fossil fuels are rich in hydrocarbons and they release these gases when burned. Mainly methane and other hydrocarbon gases intensely absorbs the temperature which is radiating away from the earth and thus the heat is trapped inside.
Therefore, by eliminating fossil fuels, greenhouse effect can be prevented.

The momentum change of the running back is - 664.2 kg m/s or 664 west.
<u>Explanation:</u>
Momentum is defined as the change in velocity of any object along with its mass. So mathematically, momentum can be derived using the product of mass with the change in velocity.
As here mass is given as 82 kg and the initial velocity was 5.6 m/s and final velocity is 2.5 m/s.
Initial Momentum = 
Final Momentum = 
Momentum change = Final Momentum - Initial Momentum
Momentum change = - 205 - 459.2 = - 664.2 kg m/s or 664 west
Thus, the changing momentum is -664.2 kg m/s. The negative sign indicates that the momentum is acting in the opposite direction on changing in the direction of velocity.
