sorry I'm late but the answer is the 2nd option
Answer:
<u>True</u>
Explanation:
Many nuclear scientists believe that when fusion power is used in powering spacecraft, this will shorten the travel time to planetary bodies.
However, one may wonder: <em>what is fusion power? </em>In simple words, it is a form of energy that uses heat released when lighter elements combine together to form heavier elements. In this fusion process, a huge amount of energy is released which can be harnessed and termed fusion power.

Answer:
u = 6.667 cm
Explanation:
given,
Focal length of the concave mirror, f = 20 cm
magnification factor = 1.5
we know,
v is the distance of the image
u is the distance of the object
v = -1.5 u
Using mirror formula
u = 6.667 cm
distance of the person from the mirror is equal to 6.667 cm.
The problem stated above is a simple conversion problem. To be able to convert from one unit to another unit, we should know the relation of the units. In this case, we need to know the relation of megabytes and gigabytes. From literature, it is known that 1 gigabyte is equal to 1000 megabyte so we use this. We converts as follows:
4.7 GB ( 1000 MB / 1 GB ) = 4700 MB
