Answer:
5 sq. root 3
Explanation:
theta= 60°
=> u sin theta = 10 × sin 60
= 10× sq. root 3/2
= 5 sq. root 3
Answer:
Halving the wavelength doubles the frequency and, thus, doubles the energy of the incident photons. This doubles the energy given to each electron, nearly doubling its kinetic energy after it is free from the metal.
Answer:
He made it, he across safely the river without falling ing.
Explanation:
Vt= 7.8 m/s
r= 11m
m= 80.5 kg
Vt= ω * r
ω= 0.71 rad/s
ac= ω² * r
ac= 5.54 m/s²
F= m * ac
F= 445.97 N < 1,000 N
Electrons are important to the electric current because they are able to move from one atom to another. When an atom loses an electron, it becomes positively charged and when an atom gains an electron, it becomes negatively charged.
