They attract, that they are inside our Earth and they make magnetic shield that protect us
That would be
Answer (B), my friend
A surface wave is a combination of a transverse wave and a longitudinal wave. A transverse wave is a wave in which particles of the medium move up and down perpendicular to the direction of the wave. A longitudinal wave is a wave in which particles of the medium move parallel to the direction of the wave. In a surface wave, particles of the medium move up and down as well as back and forth. This gives them an overall circular motion.
Answer:
1.06 × 10^5 J
Explanation:
We have to use the formula;
log(k2/k1) = Ea/2.303 ×R (1/T1 - 1/T2)
Given that;
k1 = 1.10 × 10-4 s-1
k2= 1.02 × 10-3 s-1
Ea=?
R=8.314 Jmol-1K-1
T1= 470. °C
T2= 510. °C
Hence;
log(1.02 × 10-3 s-1/1.10 × 10-4 =Ea/2.303 ×8.314(1/470 -1/510)
0.9672 = Ea/19.122(2.13 - 1.96) × 10^-3
0.9672= Ea/19.122(0.17) × 10^-3
0.9672= 1.7 ×10^-4 Ea/19.122
19.122 × 0.9672 = 1.74 × 10^-4Ea
Ea= 19.122 × 0.9672/1.74 × 10^-4
Ea= 18.495/1.74 × 10^-4
Ea= 1.06 × 10^5 J
Answer: C6H6
Explanation:
The molecular formula C₆H₆ represents Benzene. Benzene is colorless, flammable, and has a sweet and gasoline-like odor. It's a toxic chemical, and can cause cancer.
Benzene is a hydrocarbon and used for the manufacturing of products such as plastic, detergents, glues, dyes, and rubber. It can also be used in making wall-filling material.
