Mathematical equations can express dependencies between things, for example the relationship between the speed and acceleration. This can be summarized under "scientific laws".

More complex laws can represent models, for example a model of a human brain on a neuronal level could be based on complex mathematical equations.

A model and a law can be expressed as mathematical equations.

A model could be an illustration of a concept, associate degree object or maybe a method or a system that's wont to describe and make a case for phenomena that can't be practiced directly. Models are central to what scientists do, each in their analysis also as communicating their explanations. A scientific law could be a statement supported by continual experimental observations describing the facts of the universe. For example, Newton's laws of motion have complex mathematical equations.

A person is standing on a scale in an unmoving elevator. The elevator starts to move upwards at 1 m/s squared. Is the scale read

timama [110]

Answer: GREATER

Explanation:when elevator does not move it reads weight of the person . when elevator moves up let apparent weight be F . W acts downwards so net force is F-W

HENCE

F-W =ma

F= ma+W

AS a= 1 m/s^2

F = m (1)+W

HENCE GREATER

What will happen if a car experiences a 300 N force to the right from the engine and a separate 150 N force due to friction and

gayaneshka [121]

Force applied on the car due to engine is given as

$F_1 = 300 N$ towards right

Also there is a force on the car towards left due to air drag

$F_2 = 150 N$ towards left

now the net force on the car will be given as

$\vec F_{net} = \vec F_1 + \vec F_2$

now we can say that since the two forces are here opposite in direction so here the vector sum of two forces will be the algebraic difference of the two forces.

So we can say

$F_{net} = F_1 - F_2$
