Answer:
0,93 atm
Explanation:
For this we will use PV = nRT
P is what we want to find
V = 1 L
n = = 0,038 moles
R = 0,082
T = 25°C = 298,15 K
P * 1 = 0,038 *0,082 * 298,15
P = 0,93 atm
A wave vibrates up and down 22 cycles in 7 seconds with a wave speed of 57. Calculate the
1 answer:
Answer:
18.14m
Explanation:
Given parameters:
Frequency = cycles/s
Speed of wave = 57m/s
Unknown:
Wavelength = ?
Solution:
The speed of a wave is related to frequency and wavelength using the expression below;
V = f x λ
V is the speed of the wave
f is the frequency
λ is the wavelength
Insert the parameters and find λ;
57 = x λ
λ = 57 x = 18.14m
