The Earth’s core is cooling down very slowly over time. One day, when the core has completely cooled and become solid, it will have a huge impact on the whole planet. Scientists think that when that happens, Earth might be a bit like Mars, with a very thin atmosphere and no more volcanoes or earthquakes. Then it would be very difficult for life to survive – but that won’t be a problem for several billions of years.
Answer:
here's the proof
Explanation:
x-1=0
x=1
so
f(x)=x⁴-2x³+x²-x+1
f(1)=1⁴-2.1³+1²-1+1
f(1)1-2+1-1+1
f(1)=2-2
f(1)=0
as we know When f(c)=0 then x−c is a factor of f(x)
hence x-1 is a factor of x⁴-2x³+x²-x+1

<u>Answer:</u>
<em>The appropriate response is gravity: an undetectable power that pulls objects toward one another.</em>
<u>Explanation:</u>
Thus, the closer items are to one another, the more grounded their gravitational draw is. Earth's gravity originates from all its mass. <em>All its mass makes a consolidated gravitational draw on all the mass in your body.</em>
The power/mass proportion is the equivalent for each. A straightforward guideline to hold up under as a primary concern is that all items <em>(paying little heed to their mass)</em> experience a similar increasing speed when in a condition of free fall.
<em>At the point when the main power is gravity, the speeding up is a similar incentive for all articles. On Earth, this speeding up worth is 9.8 m/s.</em>
