Answer:
If light cannot get through an object, the surface on the other side of that object (for example, the ground or a wall) will have less light reaching it. A shadow is not a reflection, even though it is often the same shape as the object. The shape of the object determines the shape of the shadow
A shadow has the same shape as the object casting it when viewed in a cross-section along the line of projection. The ultimate projected shape of the shadow is distorted when it hits a surface because of the angle and design of the surface. This is how the light model helps us to explain what is the shape of the shadow.
What is the shape of a shadow?
Very interesting query. In essence, a shadow is a projection. It is the point at which the original object's shape's contour crosses another surface.
Thus, it is simple to explain yet difficult to describe.
Take the most basic shape, a ball. Therefore, the shadow of the ball will essentially have a circular cross-section. It will look like a cone of darkness stretching away from the light source and out from the back of the ball. It becomes a circle if we just project that shadow onto a wall that is parallel to the centerline of the cone. Due to the wall's surface overlapping the shadow's cross-section, the shadow will still be a circle.
In short, The shape will overall be the same but the size will be determined by a number of factors-
The distance from the light source and the angle at which the light rays strike the object both affect how large the shadow will be.
A greater shadow is cast on an object when the light source is nearby compared to when it is farther away.

A driver of a car moving with speed 90km/h saw a child on the road 25m ahead of him .he jammed on the brake and bought the car to rest and retradation of the car
Complete question :
A driver of a car moving with speed 90km/h saw a child on the road 25m ahead of him .he jammed on the brake and bought the car to rest. Calculate the time taken to bring the car to rest and retradation of the car.
Answer:
t = 2 seconds ; retradation = - 12.5 m/s²
Explanation:
Given that :
Final velocity v = 0
Initial Velocity u = 90 km /hr = (90 * 1000)m / 3600s = 90000m/3600s = 25m/s
Distance = 25 m
Using the relation :
v² = u² + 2aS
where, S = distance covered a = retradation
0 = 25² + 2a(25)
0 = 625 + 50a
50a = - 625
a = - 12.5 m/s²
Time taken (t) :
Using :
v = u + at
0 = 25 + (-12.5 * t)
0 = 25 - 12.5t
12.5t = 25
t = 25 / 12.5
t = 2 seconds

How do the high middle ages medieval cities compare with cities of today?
Medieval cities with their agrarian societies and simple market economies may seem different from modern European urban centers. Life in 14th-century cities were centered mainly around hierarchical institutions such as the crown, guilds, and churches. While as today, companies, technologies, and a global economy dominate our lives.
Answer:
Medieval cities were usually little and crowded. They were narrow and could be up to four stories high. Most of the homes were manufactured from wood, and that they tended to lean over time. Designed on riverbanks or close to monasteries and castles, they ranged from sparsely inhabited to densely inhabited.
But nowadays we got really advanced technologies and we've come with the modern cities, which are highly advanced.

Sitcoms originated in radio, but today are found mostly on television as one of its dominant narrative forms. A situation comedy television program may be recorded in front of a studio audience, depending on the program's production format. The effect of a live studio audience can be imitated or enhanced by the use of a laugh track.

Explanation:
You asked, I answered.
Hope this helped! :)
Answer:
Li, Confucian concept often rendered as “ritual,” “proper conduct,” or “propriety.” Originally li denoted court rites performed to sustain social and cosmic order. Confucians, however, reinterpreted it to mean formal social roles and institutions that, in their view, the ancients had abstracted from cosmic models to order communal life. From customary patterns, li came to mean conventional norms, yielding a new concept of an internalized code of civility that defined proper human conduct. It is this concept that is both celebrated throughout the early corpus of Confucian literature and codified in the Confucian classic called the Liji (“Record of Rites”). Transcending mere politeness or convention, li is central to Confucian human-centred religiousness. A derivative of natural order, li retains a cosmic role in its enchantment of human experience by harmonizing it with nature.
