Answer:

v₂ = 48 mph

Explanation:

We know that,

Speed = distance/time

A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.

We need to find the speed to cover the same distance in 3 hours.

\dfrac{v_1}{v_2}=\dfrac{t_2}{t_1}\\\\v_2=\dfrac{v_1t_1}{t_2}\\\\v_2=\dfrac{36\times 4}{3}\\\\v_2=48\ mph

So, the new speed is 48 mph.

What is the magnitude of the force needed to keep a 60 newton rubber block moving across level,dry asphalt in a straight line at
pantera1 [17]

let Coefficients of Friction of Rubber on asphalt (dry) =0.7

F= Coefficients of Friction * normal force = 0.7 * 60 =42 N

so the net force of the rubber is zero, meaning it will travel at a constant speed.

When the rubber is travel at 2m/s, 42N is required to keep moving at constant speed

Thepotemich [5.8K]

Answer:

He made great advancements in developing a logical way to know more about the universe and celestial entities inside the space. And this theory is termed to be heliocentric in nature.

Explanation:

  • In early times most of the people believed that our planet Earth is the center of the universe or the solar system and rest of the celestial entities move around it in a given path, so, it confused the well known scientist named as Galileo Galilei. As, he observed the different dark patches or shadow like textures on the face of the Sun.
  • While, it is more obvious to known that any object having multiple small shadows means that it is present inside such a region that all of the celestial entities move or orbit around it in a given way.So, he concluded that planet Earth itself move around the red Giant in a given way rather then being the center of the universe.
