Answer:
They had different beliefs and backgrounds.
Explanation:
Ptolemy believed in geocentric model of the solar system -the earth at the center and the sun, other planets and stars revolved about it. His belief was based on his observation that sun and other objects in sky seemed to revolve about the Earth as they rose and set in one day.
Copernicus while reading a book, constructed the theory of heliocentric system which was later proved through observations.
Answer:
At Saturn's center is a dense core of metals like iron and nickel surrounded by rocky material and other compounds solidified by the intense pressure and heat. It is enveloped by liquid metallic hydrogen inside a layer of liquid hydrogen—similar to Jupiter's core but considerably smaller
Explanation:
Answer:
The speed traveled by the car is 40 meter per second.
Explanation:
The formula for the relation between the power and the force is as follows:
P = Fv
Where F is the force and v is the speed.
As given
To travel at constant speed, a car engine provides 24KW of useful power. The driving force on the car is 600N.
F = 600 N
Convert power from KW to W.
1 KW = 1000 W
24 KW = 24 × 1000 W
= 24000 W
Thus
P = 24000 W
Put these values in the formula.
24000 = 600 × v
24000 = 600v

v = 40 meter per second .
Therefore the speed of the car is 40 meter per second .
C. Rotations per second
Or normally we'd use Radians Per second
