Answer:
Newton's Cradle is a neat way to demonstrate the principle of the CONSERVATION OF MOMENTUM.
What happens here is when the ball on one end of the cradle is swung and it hits the other balls that are motionless, or stationary, the momentum of the swinging ball is transferred to the next ball upon impact.
Momentum is not lost in this action, what happens when it hits the next ball, the momentum is transferred to the next one, and then the next, and the the next, till it reaches the last ball on the other end. Since nothing is next to the last ball, it pushes the ball upwards, which will swing down and repeat the process going the other way.
This also demonstrates the CONSERVATION OF ENERGY. As you will see, the energy continues to move through the other balls, passing it from one ball to the other, which keeps this constantly moving.
A as the lower temperature in Celsius corresponds to a lower Kelvin temperature thus reducing movement
1 result would be the decimation of crops and vegetation, which causes a reduction in farmers income rates which could lead to his workers losing their jobs or even poverty

a binary compound is a substance composed of exactly two different elements, which are substances that cannot be simplified further by chemical means.
Mg(s) + 2HCl(aq) = H₂(g) + MgCl₂(aq)
v=300 ml=0.3 l
c=4 mol/l
n(HCl)=vc
m(H₂)/M(H₂)=n(HCl)/2
m(H₂)=M(H₂)vc/2
m(H₂)=2.0g/mol·0.3 l · 4mol/l /2 = 1.2 g
1.2 grams of hydrogen gas will be produced
