C. in a covalent bond, they are shared by two atoms, while in an ionic bond, they are transferred
Answer:
m = 3.57
Explanation:
Given that,
Sergei uses a lever to lift a heavy rock. He obtains a 2.5m lever and places the fulcrum 0.7m from the rock.
We need to find the ideal mechanical advantage of Sergei's lever.
It is equal to the ratio of resistance arm to the effort arm. In terms of length it is given by :

So, the ideal mechanical advantage of the lever is 3.57.
Answer:
11.35 m/s
Explanation:
Given,
Weight of the bucket = 15 lb
radius of curvature, r = 4 ft
Minimum speed of the bucket = ?
Using equation of centripetal acceleration





Speed of the bucket = 11.35 m/s
So we want to know in which series would the emitted light belong if the electron in a hydrogen atom would go from the energy level n=5 to n=1. The correct answer is Lyman series. Complete Lyman series is from energy level n=6 to n=1. All of the wavelengths in the Lyman series are in the ultraviolet part of the electromagnetic spectrum.
