Answer:
False.
Explanation:
Removing the radiator cap will harm you. If the engine is hot and you open the radiator cap then it will cause the liquid boil, pushing the coolant out of the radiator and spraying around the liquid which can harm the person who is opening that cap. So you should aware of the risk and be prepared to avoid danger.
The answer would be Power
Answer:
k_2 = 7.815 * 10^-3 s^-1
Explanation:
Given:
- rate constant of reaction k_1 = 7.8 * 10^-3 s^-1 @ T_1 = 25 C
- rate constant of reaction k_2 = ? @ T_2 = 75 C
- The activation energy E_a = 33.6 KJ/mol
- Gas constant R = 8.314472 KJ / mol . K
Find:
- rate of reaction k_2 @ T_2 = 75 C
Solution:
- we will use a combined form of Arrhenius equations that relates rate constants k as function of E_a and temperatures as follows:
k_2 = k_1 * e ^ [(E_a / R) * ( 1 / T_1 - 1 / T_2 )
- Evaluate k_2 = 7.8 * 10^-3* e^[(33.6 / 8.314472)*(1/298 -1/348)
- Hence, k_2 = 7.815 * 10^-3 s^-1
Answer:
3.body
Explanation:
Both P and S waves are both body waves. Body waves are waves that travels through the earth.
P and S waves are elastic seismic waves that moves within the earth. Love and Rayleigh waves are surface waves that travels through the surface.
- P waves is also known as primary waves
- S waves are known secondary waves.
These waves are the first set of waves to arrive a seismic station before the surface waves are picked up.
Not sure .sorry I just don't understand.
