1 answer:
denis23 [38]3 years ago
6 0

Answer:

Option (3)

Explanation:

Nicolaus Copernicus was an astronomer from Poland, who was born on the 19th of February in the year 1473. He played a great role in the field of modern astronomy.

He was the person who contributed to the heliocentric theory. This theory describes the position of the sun in the middle of the universe, and all the planets move around the sun. This theory was initially not accepted, and after about a century it was widely accepted.

This theory describes the present-day motion of the planets around the sun in the solar system. This theory replaced the geocentric theory.

Thus, the correct answer is option (3).

Nataly [62]

Answer:

Ca = 2

Cl = 2

O = 6

Explanation:

Element given from the question above include = 2CaClO₃

NOTE: The 2 in front of CaClO₃ is affecting Ca, Cl and O.

Thus, the number of each atom of element present in 2CaClO₃ can be obtained as follow:

Ca = 1 × 2 = 2

Cl = 1 × 2 = 2

O = 3 × 2 = 6

Thus,

Ca = 2

Cl = 2

O = 6

BB8 is an intergalactic robot (essentially a soccer ball with a half meter radius that can control how fast it rolls around) tha
hram777 [196]

Answer:

20 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

r = Radius of robot = 0.5 m

\alpha = Angular acceleration = 2 rad/s²

Linear acceleration is given by

a=r\alpha\\\Rightarrow a=0.5\times 2\\\Rightarrow a=1\ m/s^2

s=ut+\frac{1}{2}at^2\\\Rightarrow 50=0t+\frac{1}{2}\times 1\times t^2\\\Rightarrow t=\sqrt{\frac{50\times 2}{1}}\\\Rightarrow t=10\ s

While speeding up time taken is 10 seconds

v=u+at\\\Rightarrow v=0+1\times 10\\\Rightarrow v=10\ m/s

s=ut+\frac{1}{2}at^2\\\Rightarrow 50=10t-\frac{1}{2}\times 1\times t^2\\\Rightarrow t=\sqrt{\frac{50\times 2}{1}}\\\Rightarrow 50=10t-0.5t^2\\\Rightarrow -5t^2+100t-500=0

t=\dfrac{-100\pm \sqrt{100^2-4\left(-5\right)\left(-500\right)}}{2\left(-5\right)}\\\Rightarrow t=10\ s

The time taken to slow down is 10 seconds

Total time the trial is rum is 10+10 = 20 seconds
