Answer:
I don't knowI think it will break
Answer:
The velocity of the particle = -1.92 m/s
The speed of the particle = 5.72 m/s
Explanation:
Given equation of motion;
Velocity is defined as the change in displacement with time.
The distance traveled by the particle in 5 s:
The speed of the particle when t = 5s
Answer:
temperature change is 262.06°K
Explanation:
given data
mass = 0.07 kg
velocity = 258 m/s
to find out
what is its temperature change
solution
we know here
heat change Q is is equal to kinetic energy that is
KE = 0.5 × m× v² ...........1
here m is mass and v is velocity
KE = 0.5 × 0.07 × 258²
KE = 2329.74 J
and we know
Q = mC∆t .................2
here m is mass and ∆t is change in temperature and C is 127J/kg-K
so put here all value
2329.74 = 0.07 × 127 × ∆t
∆t = 262.06
so temperature change is 262.06°K
<span>The heliocentric model of the
universe was proposed by Nicolaus Copernicus. There are numerous scientist in
ancient times who try to explain what happens in the universe. He may not be
the first one who proposed that what astronomical body is the center of the
universe. However, he stated that the center of the universe was the sun, not
the earth. And the earth revolves around it. It is in his book on the
Revolutions of the Heavenly Bodies. It was only published as he lay in his
deathbed. </span>
