Answer:90N
Explanation:
Mass=30kg
Centripetal acceleration=3m/s^2
centripetal force=mass x centripetal acceleration
Centripetal force=30 x 3
Centripetal force =90
Centripetal force =90N
Answer:
A
Explanation:
Opposite attract. Since electrons are negative they will be attracted to the protons because they a positive
Answer:
thermal energy
Explanation:
heat transfers into it causing it to physically change
V = f(wavelength)
22.0 = 0.0680 (wavelength)
wavelength = 323.52 m
