The Chemical fomulla for Zinc Phosphate
Zn3(PO4)2
Answer:
radio waves are the sound waves that are produces by a radio
Explanation:
Answer:
Has a positive charge
Explanation:
Protons inside the nucleus help bind nucleus together. They also attract negative charged electrons.
In science negative to negative/positive to positive repels and negative to positive or vice versa attract to each other.
Answer:
option e = 1.99 × 10⁻⁶ m
Explanation:
Given data:
Mass of electron = 9.11 × 10⁻²⁸ g or 9.11 × 10⁻³¹ Kg
Velocity = 3.66 × 100 m/s
Wavelength = ?
Solution:
Formula:
λ = h / m. v
λ = wavelength
h = planck's constant
m = mass
v = velocity
Now we will put the values in equation
λ = h / m. v
λ = 6.63 × 10⁻³⁴ Kg. m²/s / 3.66 × 100 m/s . 9.11 × 10⁻³¹ Kg
λ = 6.63 × 10⁻³⁴ Kg. m²/s / 3334.26 × 10⁻³¹ Kg .m/s
λ = 1.99 × 10⁻⁶ m
