Answer: 5040 joules
Explanation:
How much energy is released when 150g of silver cools from 220°C to 80°C?
Given the following :
Mass (m) of silver = 150g
Change in temperature (ΔT) = (220 - 80)°C = 140°C
Q=mcΔT
Where Q = quantity of heat
m = mass of silver ; c = specific heat capacity
Specific heat capacity of silver = 0.240 j/g°C
Q = (150 * 0.240 * 140)
Q = 5040J
Ecozone is
divergent environment wherein the biotic community, plants, animals and people
and non-biotic community, lithosphere, atmosphere and hydrosphere communicate
and process.

Explanation:
Alfred Wegener in 1915 published 'The Origin of Continents and Oceans'. But geologists denounced his theory. Wegener's Continental drift is the theory that the different continents of the planet earth have moved over time causing them to shift positions. he thought all continents were once joined together before breaking up to different positions.
Part of the objections he faced was because he did not have much evidences to back up his theory.
Answer:
Responses to a shrinking population are birth bonuses, governments reducing taxes or paying for part of daycare for new parents, and policies or rules that allow for parents to work flexible hours, part-time and/or take leaves from work without losing their jobs.
Explanation:
A is correct because by giving bonuses to the parents for every child they have, the governments are trying to stimulate them economically to do so.
B is not correct because advertising to take your children somewhere doesn't help people deciding to have or not have children.
C is correct because the governments are trying to reduce the economic burden on the parents and help them out with the raising of their children.
D is correct because through this measure the governments are giving the parents economic security and stability while enabling them to be with their children whenever necessary.
E is not correct because such a measure will have a countereffect.
