The total mass of the things on the road is 60 + 13, which is 73kg.
mass • acceleration = F
73 x 0.9m/s^2 = 65.7N
F = 65.7 N
No but the sun could be a white dwarf stellar remnant.
mass is the same, weight is less because weight =mass ×gravity
Firstly models are just predictors, they are not exact models. Exponential growth <span>models are good when populations are small relative to the amount of resources available. ... This is where the </span>exponential<span> model breaks down. The </span>logistic<span> function tries to compensate for this with the carrying capacity.</span>
