<u>Answer:</u>
"The Sun's diameter is about five times that of Earth" is not true about the sun.
<u>Explanation:</u>
The Sun at the pivotal of the solar system is a star and covers 99.86% of the total mass of the system. Approximately 73% mass of the sun is due to hydrogen gas while nearly 25% mass due to helium and for the remaining mass small amount of heavier elements like carbon, oxygen, neon and iron are responsible.
The diameter of the sun is 864,000 miles or 1.39 million km or 109 times of the Earth while mass is 330,000 times of the Earth's mass. Sun is a almost perfect sphere of hot plasma with internal convective motion responsible for production of a magnetic field through a dynamo process. And the most important source of energy on Earth for life.
Answer:
Explanation:
Let the charge on bead A be q nC and the charge on bead B be 28nC - qnC
Force F between them
4.8\times10^{-4} = 
=120 x 10⁻⁸ = 9 x q(28 - q ) x 10⁻⁹
133.33 = 28q - q²
q²- 28q +133.33 = 0
It is a quadratic equation , which has two solution
q_A = 21.91 x 10⁻⁹C or q_B = 6.09 x 10⁻⁹ C

Answer:
Honda Civic
Explanation:
As per the structural design and purpose of use for vehicle, Both are different from one another in various terms such as size, strength and design.
Mack trucks are very huge trucks especially designed for loading heavy objects. They are even used to carry heavy consignments such as cars.
Whereas Honda civic has a sleek structural design and have a very fragile body as it is sedan car, so if there will be a head-on collision between these two vehicles, certainly there will be a huge impact force on civic and it will even smash into pieces if any of the vehicle have high speed.
