Answer:

Copernicus' heliocentric model

Explanation:

Nicolaus Copernicus was the first one to give the heliocentric model of the solar system. The heliocentric model of the solar system describes the sun to be at the center of the solar system and earth and other planets with their moons revolving about it in concentric orbits.

Kepler believed in Copernicus's heliocentric model but gave laws of planetary motion that described the orbit of the planets to be elliptical instead of circular.

Tycho Brahe view of the solar system was that sun revolved around earth but other planets revolved around the sun.

Ptolemy's geocentric model considered earth to be the center of the universe and sun and other planets revolving about it.

I believe it was Copernicus' heliocentric model.

heliocentric - the sun is at the center and the planets revolve around it.

hope this helps :)

an object is acted on by a drag force with a magnitude that is proportional to the speed. the object accelerates downward at 3.0
Nutka1998 [239]

The terminal speed of the object falling down is 66.67 m/s.

The terminal speed acquired by the body when,

Weight of the body = Drag force of the body

It is given,

Drag force is directly proportional to the speed,

So,

F = CV

Where F is drag force,

V is the speed,

C is the constant,

So, it can be written as C = F/V.

The weight of the body = mg

The weight of the body = 10m

M is the mass and g is the acceleration due to gravity,

The drag force when the speed is 20m/s.

Drag force = ma

a is the acceleration during the drag force which is given to be 3m/s²,

Drag force = 3m

Now we can write,

F₁/V₁ = F₂/V₂

F₁ is the drag force at 20m/s speed.

F₂ is the weight of the body and V₂ is the terminal speed,

Now, it can be written,

3m/20 = 10m/V₂

V₂ = 66.67 m/s.

So, the terminal speed is 66.67m/s.

Prove for N/C=Volt/m
Zigmanuir [339]

Answer:

simple, Volt =change in potential energy/Charge

the unit of energy is newton meter (Force*distance)

the unit of charge is coloumb

So, Volt/meter=newton* meter/coloumb*meter

=newton/coloumb (hence proved)

This unit is the potential drop per unit of length in a conductive wire with uniform resistance
