It was the finding itself that surprised me most. I was not even aware
that I had lost the key, and I was shocked, and a bit confused at first,
when I saw it there on the floor of the garage.
To do this, you need to make sure that all speeds are the same unit. Since there are three 2 speeds already in km/hr, it would be best that you match the other 2 speeds into that unit as well.
Conversion of 15,000m/hr:
time is already in hours so you just need to make convert the meters to kilometers.
Conversion of 4.3m/s
Now that they are all the same value, you can see that Fred at 4.3m/s was the fastest.
Answer:
Wave speed = 50 m
Explanation:
Given
Wavelength = 5 m
Frequency = 10 Hz = 10
wave speed = ?
We know that all waves have same relationship among wavelength λ, frequency f and speed v , which is given by
v = fλ
Therefore wave speed = 10 x 5 m = 50 m
Answer:
w = 2w₀ the angular velocity of man doubles
Explanation:
In this exercise, releasing the weights reduces the moment of inertia
I= I₀ / 2
Therefore, since the platform system plus man is isolated, the kinetic moment must be conserved
L₀ = L
I₀ w₀ = I w
I₀ w₀ = I₀ / 2 w
w = 2w₀
therefore the angular velocity of man doubles
