Answer: f = 392 hz
v = 343 m/s
wavelength = 343/392 = 0.875 m
hope this helped!
Answer:
Explanation:
Recall that in this case, friction is not taken into account. Thus, Using the free body diagram, according to Newton's second law, we have:
For the lighter block:
For the heavier block:
The acceleration is the same for both blocks:
So, replacing (2) in (1):
Answer:
5.36 times bigger
Explanation:
The radius of the Earth is:
so its diameter is
The radius of Pluto is:
So its diameter is
So the ratio between the two diameters is
So the diameter of the Earth is 5.36 times bigger than the diameter of Pluto.
Answer:
Emissions per second = 0.36
Explanation:
Please find the attached question
Solution
Given
Let X be the rate of background emission.
X = B/t
Where B = 36
And t = 100
X = 36/100 = 0.36
