Crops need sunlight to grow as well as water.
Reduced sunlight means reduced growth rate of crops means reduced crop yield means reduced number of mouths each yield can feed means famine means death.
Answer:
B
Explanation:
because, convection is the transfer of heat between fluid substances/materials
Since the acceleration is uniform, we can calculate it from the data we are given:
a = (vf - vi)/2
where vf=33 m/s and vi=11 m/s
Then use Suvat's equation:
x(t) = vi*t + 0.5 * a * t
where t=20s
Answer:
2nd option
Explanation:
Static electricity the charges are at rest and they are accumulating on the surface of the insulator.
Current electricity the electrons are moving inside the conductor.
