An observer stands at the tip of the dark blue arrow in the diagram the view of the sun from the observer’s point of you is the following
Explanation:
1.The region of complete shadow is called the umbra and the region of diffuse shadow is called the penumbra. These shadows are formed on the Earth during a solar eclipse and From the umbra we see a total eclipse while from the penumbra only a partial eclipse is visible.
2.There are four different types of solar eclipse, namely Partial eclipse, Annular eclipse, Total Eclipse and Hybrid Eclipse. A partial solar eclipse occurs when only part of the Sun is covered by the Moon which appears to take a “bite” out of the Sun.
3.Solar eclipses can only occur during a New Moon when the Moon moves between Earth and the Sun and the 3 celestial bodies form a straight line: Earth–Moon–Sun. There are between 2 and 5 solar eclipses every year. There are 3 kinds of solar eclipses: total, partial, and annular.
4.You can see from the two diagrams that there are two types of shadow; a crisp edged one formed by a point source of light and a rather more fuzzy one that is formed by a larger source. The region of deep, total shadow is called the UMBRA and the region of partial shadow is called the PENUMBRA.
5.umbra. The very darkest part of a shadow is the umbra. It's where the light source is completely blocked by the object in front of it.
6.The Moon's shadow actually has two parts:
Penumbra. The Moon's faint outer shadow. Partial solar eclipses are visible from within the penumbral shadow.
Umbra. The Moon's dark inner shadow. Total solar eclipses are visible from within the umbral shadow.

Answer:
Forces 1 and 2 cannot have equal magnitudes.
Force 1 exceeds force 2.
Explanation:
Numbering the given statements:
- The force of the horse pulling on the cart.
- The force of the cart pulling on the horse.
- The force of the horse pushing on the road
.
- The force of the road pushing on the horse.
- When a horse pulls a cart along a flat road starting from the state of rest, the horse applies a force on the ground in downward-back direction diagonally and as its reaction it moves forward. During this action there is also a reaction force by the road on the horse which exceeds the force of the horse on the ground and as a result the horse moves forward.
- For pulling the cart the horse applies the force on the cart in the forward direction and as a reaction the cart applies a force on the horse in the backward direction which is less than the force of the horse on the cart resulting in the forward motion of the cart along with the horse.
You would get a wrong calculaton which if you are doing an experiment it can mess with the results
