Answer:
Answer: Given m = 10 kg and . F = 20 N. Thus, the force required to accelerate the object upward direction is 20 N.
Explanation:
2.7067 eV
h = Planck's constant =
c = Speed of light =
= Threshold wavelength = 459 nm
Work function is given by
Converting to eV
The work function W0 of this metal is 2.7067 eV
Answer:middle
Because it will make the seasaw balanced
Answer:b
due to acceleration lol
