The Hydrogen bomb is a thermonuclear bomb where a fission reaction is used to trigger a fusion reaction.
Answer: Option A
<u>Explanation:
</u>
The Concept of Hydrogen Bomb or H-Bomb is primarily based on nuclear fusion where different isotopes of hydrogen diffuse to fuse their atomic nuclei into a bigger atom, releasing a significant and enormous amount of energy that can ruin a half of the world.
A hydrogen or thermonuclear bomb contains a firearm, but the reaction process has two stages. Uses primary fission energy to activate the next fusion reaction. The energy out by the fusion is nearly four times more than the energy out during fission, which gives more power to a hydrogen bomb.
Answer: The correct answer for the blank is- a. change its position relative to other objects.
Perception of motion can be described as a phenomenon of inferring the direction and speed and of objects, which are moving in a visual scene.
An object is said to be in motion if its position is changed with respect to objects that are present in its surrounding.
Thus, in order to sense motion of objects, humans beings are required to see an object change its position with respect to other objects.
Nothing is accelerating ... it's not even moving. Everything is just sitting there.
That right there tells you that the forces are balanced wherever two things meet,
otherwise something would be accelerating.
At each level where two things meet, there are 2 forces:
-- The gravitational force ... the weight of everything above that place,
and
-- The upward force, exerted by everything below that place.
Here is the stack:
_____________
| Physics ... 2kg | weight = M G = 2 x 9.8 = 19.6 newtons
---------------------
|Calculus ..5 kg | weight = M G = 5 x 9.8 = 49 newtons
---------------------
|Econ . . . .3 Kg | weight = M G = 3 x 9.8 = 29.4 newtons
==================
-------- (Table) ----------
/ \
a). Surface where the table meets the Economics book.
Weight of everything above = (29.4 + 49 + 19.6) = 98 newtons
Upward force exerted on the Econ book by the table = 98 newtons.
b). Surface where the Econ book meets the Calculus book.
Weight of everything above = (49 + 19.6) = 68.6 newtons.
Upward force exerted on the Calc book by the Econ book = 68.6 newtons.
c). Surface where the Calculus book meets the Physics book.
Weight of everything above = 19.6 newtons.
Force exerted on the Physics book by the Calc book = 19.6 newtons.
Answer:
C. 3.2km
Explanation:
Seeing as the swimmer travels 10.8 km in an hour, and they are asking you to find how far they have traveled after 0.3 hours, multiply 10.8 km/h by 0.3 h. The h's will cancel and you are left with 3.24km, which can be rounded to 3.2km. Hope this helps! :)
The correct answer for the question that is being presented above is this one: "none of the above." Wave reflection happens there is a change in direction of a wavefront. This wavefront is at an interface between two different media, which makes the wavefront returns into where it is originated.
