Answer:
5km/h
Explanation:
The equation for average speed is
Vavg = Δd/Δt
where Δd is distance and Δt is time
from what's given, we know she travelled 15km in total and the trip took 3 hours in total. We can now plug in the values into the equation
Vavg = 15/3
Vavg = 5km/h
Answer:negative slope or gradient I think
Explanation:
I think the model being described is the Rutherford atom model. This is where he posit that atoms have a nucleus which contains positively charged protons and surrounded by electrons.

Answer:
the charge of each particular must be doubled
Explanation:
We can solve this exercise using Coulomb's law
F₀ = k q₁ q₂ / r²
tells us that the force is quadrupled and asks if the load
let's call the initial force F₀, let's find the force of the algae they double
q₁ = q₂ = 2q₀
we substitute
F = k 2q₀o 2q₀ / r₁2
F = 4 F₀
we see that for the force to multiply by 4, the charge of each particular must be doubled
