Answer:
Explanation:
The formula for centripetal acceleration is
and filling in:
and solving for r:
gives us that
r = 79.6 m
Cuz Of Newton’s third law, every actions there is an equal and opposite reaction.

Answer:
Explanation:
energy of photon having wavelength of 400 nm = 1237.5/400 eV
= 3.1 eV.
Maximum kinetic energy of photoelectrons = 1.1 eV .
Threshold energy Ф = 3.1 - 1.1 = 2 eV .
energy of photons having wavelength of 310 nm = 1237.5 / 310 eV = 4 eV .
Maximum kinetic energy of photoelectrons = energy of photons - Threshold energy
= 4 - 2 = 2 eV .
Required kinetic energy K₀= 2 eV.
Because you are not using gas oil etc, in other words you are saving fossil fuels by walking instead of driving a car
also could I get brainliest plz
