The answer is the magnetosphere
Answer:
160m/s
Explanation:
To find V Use the following formula V= F*W
V= Velocity F= Frequency W= Wavelength
V=20*8
=160m/s
False, pepsin and hydrochloric acid
Answer : a) 40075.14 J/mol
Explanation :
According to the Arrhenius equation,
or,
where,
= rate constant at = k
= rate constant at = 10 k
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature = 440 K
= final temperature = 550 K
Now put all the given values in this formula, we get
:
Therefore, the activation energy for the reaction is 40075.14J/mol.
