Mathematically, to compute for the wavelength, λ, we have
where v is the velocity and f is the frequency.
As we can see here, given that velocity is constant, wavelength increases as frequency decreases. This shows that wavelength is inversely proportional to frequency.
Answer: Wavelength and frequency are inversely related to each other.
<u>Answer</u>
4.8212×10⁻¹¹ N
<u>Explanation</u>
The gravitational force F, between 2 masses m₁ and m₂ is given by:
F = (Gm₁m₂)/d²
Where G = 6.673 x 10⁻¹¹ N m²/kg² and d is the distance between the 2 masses.
F = (Gm₁m₂)/d²
= (6.673 x 10⁻¹¹ × 0.425 × 0.425)/0.500²
= 1.2053×10⁻¹¹/0.25
= 4.8212×10⁻¹¹ N
Oxygen has Atomic number 8 so all isotopes have 8 protons and 8 electrons.
So the number of neutrons in Oxygen-18 = 18 - 8 = 10.
Option B is the correct one.
Physics
Chemistry
Physical science is science which studies non-living things.This covers things on earth to the universe.The main branches are physics and chemistry.The other sub-branches are Astronomy, meteorology and Geology.Physics is concerned with the basic principals of matter and energy.It covers concepts in motion, energy, force, pressure , light and many other areas we encounter in our day to day life.Chemistry is concerned with composition of matter and how it reacts.Material in chemistry is understood through observing molecules, atoms, elements and their interaction in nature including their properties.Chemistry is further divided into organic chemistry and natural chemistry sub-branches.

Answer:
3500N
Explanation:
Given parameters:
Mass of driver = 50kg
Speed = 35m/s
Time = 0.5s
Unknown:
Average force the seat belt exerts on her = ?
Solution:
The average force the seat belt exerts on her can be deduced from Newton's second law of motion.
F = mass x acceleration
So;
F = mass x 
F = 50 x 
= 3500N
