Describe how the motion of a planet (like Mars) among the stars of the zodiac on the sky is qualitatively different from the mot
Advocard [28]

Explanation:

In the plane of the Solar System, called Ecliptic plane, Sun is at the center and all the planets including Earth are going around the Sun in their respective orbits. As seen form the Earth, Sun appear to go around it and in this process it  crosses through 12 constellations. These constellations are called as Zodiacs. Now since all the planets move in almost the same plane, they will appear in the sky to be lying near the ecliptic.

Sun's own motion is not that evident to us because of which the impact of that motion is nullified. But, motion of planet is clearly visible and it also shows in their annual round around the Sun. Here, Mars also shows retrograde motion which means it will show a back and forth motion in the sky. Because of which Mars might be visible in the same zodiac for a longer Duration as compared to the Sun.

A bulldozer uses a 500 N force to push a load of dirt 16 m to the worksite. How much work
strojnjashka [21]

Explanation:

Force (F) = 500 N

Distance (d) = 16 m

work done (w) =?

We know that

w = F * d

= 500 * 16

= 8000 Joule.

The bulldozer performs 8000 Joule.

Hope it will help you :)❤

a crowbar having the lenght of 1.75 is used to balance a load of 500N if the distance between the fulcrum and the load is 0.5m f
goblinko [34]

The effort applied : 200 N

<h3>Further explanation</h3>

Equilibrium rotation

\large {\boxed {\bold {\sum \tau = 0}}

F₁.d₁-F₂.d₂=0

F₁.d₁=F₂.d₂

F₁=500 N

d₁=0.5 m

d₂=1.75-0.5=1.25 m

\tt 500\times 0.5=F_2\times 1.25\\\\F_2=\dfrac{500\times 0.5}{1.25}=200~N
