A snowboarder traveling at 9 meters per second snowboards to a stop at the top of a ramp in 4 seconds. What is the skateboarder’s acceleration? *

Answers

Answer 1

Answer:

Acceleration = -9/4 meter per second square

Explanation:

This problem can be solved using first equation of motion which is

v = u + at           where

v is final velocity

u is initial velocity

a is the constant rate of acceleration

t is the time of motion of body

note: this law is applicable only when acceleration is constant.

___________________________________

Given

initial velocity (u) = 9m/sec

It is given that body stops at top of ramp.

when any body is not moving its velocity is 0.

As body stops and is not moving hence its velocity is 0.

it is also the final velocity

thus,

final velocity (v) = 0

t = 4 second

we have to get a

using the equation of motion, and substituting the value as given above we have

v = u + at  

0 = 9 + a*4

0 = 9 + 4a

=> 4a = -9

=>  a = -9/4

Thus, acceleration is -9/4 meter per second square.

negative sign implies that acceleration is opposite of the direction of velocity.

This, it also intuitive as body speed is decreasing, it can be understood that direction of acceleration is opposite to that of velocity

Acceleration in improper fraction .

acceleration in mixed fraction form = -(2  1/4) meter per second square.

What is supply and demand

Answers

Answer:

Explanation:

Supply and demand should be thought of together. Suppose you need a hairbrush. You go to your local pharmacy and ask one of the clerks if they stock hairbrushes. They say no they don't. If the pharmacy is supposed to have hairbrushes and they don't, then the supply side does not meet the demand. That's too little supply.

So next you try the nearest grocery store and they say "Yes. For you it's $2.99."

Now you represent the demand, and the store represents supply. They have the hairbrush you want. But the store won't stock hairbrushes if in the last year, you are their first customer who wanted a hairbrush. You still provide the demand, but there is no supplier. So you go without a hairbrush.

The same thing can happen to the supply side. The store has 25 hairbrushes. You only want one. There are too many brushes on the supply side. The store, if they do that with everything, will go broke. Too much supply is just as bad as not enough.

Doug and tasha are learning about behavior problems. doug says behavior problems occur when socialization isn't performed during the sensitive period. tasha says behavior problems occur when the animal doesn't understand what the owner wants. who is correct?

Behavior disorder can be worked upon especially when the animal is young to help him have a normal life. The individual is taught how to relate with other animals, social activities this helps overcome disorder

Answer:both Doug and Tasha are correct.

Explanation:Doug and Tasha are explaining behavior problems that can arise in animals .

Socialization in animals occurs through the process of preparing an animal usually a pet to learn how to enjoy to interact with the owner and be comfortable with exposure to other people, other animals, objects  activities etc. For example, it is important that training on socialization should begin between 3 and 14 weeks of age for puppies and 3 and 9 weeks of age for kittens These periods are called the  sensitive period which these animals can learn.

Behavior problems occur in animals if socialization is not performed during the sensitive periods which can lead to the animal not understanding how to interact or know what it owner wants.

An object's velocity can be described by its acceleration and direction.


True or false

Answers

Answer:

False

Explanation:

An object's velocity can be described by it's direction. Because velocity is a vector. Besides velocity and acceleration are different units they can't be described by each other.

It is completely inappropriate to mention that the velocity of an object can be described by its acceleration and direction. Therefore, the statement given above is false.

What is the significance of velocity of an object?

The velocity of an object can be referred to or considered as a change in the position of an object due to a displacement that takes place in the position of any given object. The displacement in position and time taken for displacement are the determinants of a velocity.

The acceleration of the object in not at all helpful in determining the velocity or displacement of an object in a given amount of time. Direction does help in determining the velocity of an object, but it also has exceptions in its determination.

Therefore, the statement given above that states regarding the significance of the velocity of an object is false.

After conquering an area, what aspects of that society did Genghis Khan keep?



Plz help I will mark you brainlest

Answers

Answer:

During the early stages of Mongol supremacy, the empire established by Genghis absorbed civilizations in which a strong, unified, and well-organized state power had developed. The social organization of the Mongols was, however, characterized by pastoralism and a decentralized patrilineal system of clans. Antagonism existed between a society of this nature and the subjugated advanced civilizations, between a relatively small number of foreign conquerors and a numerically strong conquered population. In the early phases of conquest, the Mongols usually attempted to impose the social structure of the steppes upon their new subjects. It was customary for the Mongols to enslave a conquered tribe and to present whole communities to distinguished military leaders as a sort of personal appanage. These slaves became sooner or later an integral part of the conquering tribe. In the conquered areas a similar procedure was adopted. Groups of the settled population, usually those living in a certain territory, became the personal property of Mongol military leaders who exploited the local economic forces as they liked. No use was made of theexisting state machinery or bureaucracy, and the former political divisions were entirely disregarded. Nor was there any attempt to organize the numerous local Mongol leaders who enjoyed a high degree of independence from the court of the khans. Ruthless exploitation under strong military pressure was therefore characteristic of the early phase of Mongol domination, which may be said to have lasted until about 1234, some seven years after Genghis Khan’s death.
