Answer:
What if what if what if what if?
Explanation:
What if- I turn into a What if ?
I believe the biggest space mission of the twenty-first century will be a manned mission to Mars, and the colonization that follows. This is the stated goal of several nations, companies, and individuals, all with considerably deep pockets. This mission will not only be a huge leap forward in space exploration, it will usher in a new era in human history in which the human race is an interplanetary civilization, a natural milestone as humanity continues to progress and advance.
Significant challenges are many and overwhelming. In terms of getting to mars, we need efficient, powerful propulsion systems and a spaceship that can not only accommodate a full crew for a mission that would likely last years, but withstand the various hazards that a long trip through space and entrance into the Martian atmosphere will entail. In terms of colonization, significant challenges will include establishing efficient and frequent travel/transport between the planets, and in the longer term, the necessity to terraform the planet (make it more like Earth) so that humans can more easily live there.
Answer:
Because it is a muscular body organ
<span>You
are right in that bananas contain potassium and K-40 is a naturally
occurring potassium isotope AND the K-40 in an average banana does decay
at a rate of about 31 ATOMS per second (half-life is > 1 billion
years). This is an extremely low level of radiation and nothing to worry
about. Bananas will definitely NOT cause a "nuclear winter."</span>
Answer:
The changing variables are: v and KE
Explanation:
Given
Required: What changes?
From the formula above:
m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater.
KE: When velocity changes, the kinetic energy also changes
So:
The changing variables are: v and KE
