Im sorry i can only do the last one the answer might be a, d, e. Im so sorry if im wrong
Answer:
Explanation:
To solve this problem, we have to remember the ideal gas theory. We going to use the Gay Lussac Law.
The equation is:
PiTo = PoTi
Where:
<em>Pi =initial pressure</em>
<em>Po = final pressure</em>
<em>Ti = initial temperature</em>
<em>To = final temperature</em>
Let's use this equation and replace the values:
<em>Pi = 107 kPa</em>
<em>Ti = 22°C</em>
<em>To = 45 °C </em>
<em>Po = ? </em>
<em />
You can use the units as the problem gave you.
Using the Gay Lussac law:
107 kPa x 45 °C = Po x 22°C
Po = (4,815 kPa°C / 22°C) = 218.86 kPa
Po = 218 kPa
A.) slower, low is the answer your answer let me know if I got it right 99.9% I’m right
Answer:
f = 1.87 × 10¹⁹ s⁻¹
Explanation:
Given data:
Wavelength of light = 1.6 ×10⁻¹¹ m
Frequency of light = ?
Solution:
Formula:
speed of light = wavelength × frequency
Frequency = speed of light / wavelength
speed of light = 3× 10⁸ m/s
Now we will put the values in formula:
Frequency = speed of light / wavelength
f = 3× 10⁸ m/s / 1.6 ×10⁻¹¹ m
f = 1.87 × 10¹⁹ s⁻¹
