The answer is 40 because you just have to do 200 divided by 5
Answer:
586 K
Explanation:
Let P is the initial pressure.
Initial temperature, T₁ = 20°C = 293 K
Final pressure, P₂ = 2P
We need to find the final temperature of the gas.
The relation between the pressure and the temperature is as follows
Put all the values,
So, the final temperature of the gas is 586 K.
Complete question is The frequency of the fundamental of the guitar string is 320 Hz. At what speed c do waves move along that string? wavelength is 40 cm.
Answer:
128 m/s
Explanation:
In case where fundamental frequency is given, the speed with waves travel along the string can be calculated using the following formula:
v = f (2L) where L is the length of the string (L = λ/2)
⇒v= f λ
f = 320 Hz (given)
λ = 40 cm = 0.40 m
Substitute the values:
⇒ v = 320 Hz × 0.40 m= 128 m/s
Answer
A
Explanation:
Weight = Mass x Acceleration due to gravity
Weight = 1000 x 9.81
= 9810 or 9.81x10^ 3
