In an uniform circular motion, the direction of the net force on the object is radially inward, passing through the center of the circle.
It would be 12W because: 6v is half of 12v so half of 24w would be 12w
Answer:
11 because the number of protons is the atomic humber
Explanation:
Answer:
D
Explanation:
The answer is Niels Bohr's planetary model, the difference between this model and all of the other models is that the Bohr's PM Is more of layers of
Nucleus - Protons and Neutrons
Electron Orbital - Period 1 Elements
2 electrons

8 electrons
Electron Orbital - Period 3 Elements
8 electrons
If that made sense-
Answer:
7.2 cm
Explanation:
magnetic field, B = 0.301 T
speed, v = 7.92 x 10^5 m/s
mass, m = 4.39 x 10^-27 kg
q = 1.6 x 10^-19 C
The radius of singly changed ion is given by

where, m is the mass of ion, v be the speed of ion, B is the magnetic field and q be the charge

r = 0.072 m
r = 7.2 cm
