Explanation:
It is given that two loads have 0.75 Ampere current each. And, they contain 2500 milli ampere per hour Ni-Cd battery.
As both the loads are connected in parallel. Hence, total current will be calculated as follows.
I =
= 0.75 A + 0.75 A
= 1.5 A
=
= 1500 mA
Relation between time and capacity of battery is as follows.
Capacity = Current × time (in hour)
therefore, time =
=
= 1.667 hr
Thus, we can conclude that the battery provide power to the load up to 1.667 hours.
"the same";
One mole of any given thing is 6 * 10²³ of it;
One mole of H₂O is 6 * 10²³ molecules;
One mole of O₂ is also 6 * 10²³ molecules;
Therefore for both substances, there are the same number of molecules.

Answer:
the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.
