Answer:
3.7 m
Explanation:
We are given that
Mass of electron,m=
Magnetic filed,B=
Charge on electron,q=
We have to find the radius of circular path the electron follows.
We know that
Radius of circular path,r=
Using the formula
Hence, the radius of circular path followed by electron=3.7 m
Answer:
A
Explanation:
v = change of X / change of T
v = 200/19.3
Answer:
i. Geodynamo
ii. Gravitational energy conversion
Explanation:
The outer core of the Earth is believed to be in molten form, consisting of mainly iron and nickel. The reaction (mixture) between these components or elements generates conventional currents which is maintained by the gravitational energy produced in the process. Thus, magnetic fields are generated continuously due to the continuous flow of electric current during the processes.
Answer:
Voltage can be calculated in various ways but I am a easier solution to it:
Explanation:
V=I×R instead of this formula I use:
P=I×V
600=400×V
600=400V
Divide both sides by 400
V=3÷2
V=1.5 J/C
1volt=1coulomb or joule
Your answer would be that Hubble categorized galaxies by their shape.
