The answer is invention. Technology is vital to science for purposes
of dimension, data gathering, treatment of samples, calculation, transport to
research sites, defense from hazardous materials, and communication. So
technology is new tools and techniques that are being industrialized that make
it conceivable to progress various lines of scientific investigation.

Answer:</h2>
-310J
<h2>
Explanation:</h2>
The change in internal energy (ΔE) of a system is the sum of the heat (Q) and work (W) done on or by the system. i.e
ΔE = Q + W ----------------------(i)
If heat is released by the system, Q is negative. Else it is positive.
If work is done on the system, W is positive. Else it is negative.
<em>In this case, the system is the balloon and;</em>
Q = -0.659kJ = -695J [Q is negative because heat is removed from the system(balloon)]
W = +385J [W is positive because work is done on the system (balloon)]
<em>Substitute these values into equation (i) as follows;</em>
ΔE = -695 + 385
ΔE = -310J
Therefore, the change in internal energy is -310J
<em>PS: The negative value indicates that the system(balloon) has lost energy to its surrounding, thereby making the process exothermic.</em>

100/1=x/0.985, 98.5=x. So the distance from Orlando is 220-98.5=121.5miif he adjusts, he has 98.5 miles more to do, plus 121.5 miles he already did, the flight is 1.25 mi farther
The correct option is D.
The big bang theory is the scientific theory that explains how the universe came to exist. The theory explains how the universe expanded due to high temperature and density. Scientists believed that the first nuclei were formed few minutes after the bing bang occurred via a process called bing bang nucloesynthesis. During this process helium and hydrogen were formed and the amount of helium found correspond to the amount predicted by scientists.
