9. A train is moving with the velocity of 45 km Ihro The osives applies brace and the train gets stopped in 6 second. Now, calculate as distance covered by the train before coming to
the rest.​

Answers

Answer 1
((12.5 + 0)/2)(6)
D= 37.5 m
I think it’s 37.5 m
I basically just converted 45 km/h to m/s then used the formula d =( (initial velocity + final velocity)/ 2)(t)

A soccer ball is kicked horizontally. What is its average speed if its displacement is 21.0 m
after 2.00 s?

Answers

Answer:

Below

Explanation:

You can use this formula to find the average speed/velocity

     speed = displacement / change in time

Plugging our values in....

     speed = 21.0 m / 2.00 s

                = 10.5 m/s

Hope this helps! Best of luck <3

The average speed of a soccer ball is 10.5 m/s.

What is speed?

Speed is defined as the ratio of the distance moved by the object at a particular time. The unit of speed is measured in the meter per second, miles per hour, etc. The speed of an object is a scalar quantity and does not require any direction to represent it. It only requires magnitude to represent it.

Average velocity is defined as the sum of all the distances traveled by an object to the time taken by the object to cover the total distance.

Given that a soccer ball is kicked horizontally. its average speed if its displacement is 21.0 m after 2.00 seconds will be calculated as below:-

Speed = displacement / change in time

Speed = 21.0 m / 2.00 s

Speed = 10.5 m/s

Therefore,  the average speed of a soccer ball is 10.5 m/s.

During which portion of its motion-A, B, or C- does the train have the smallest speed?

Answers

Answer:

1

Explanation:

B is -1 m/s but it transfers to 1

During portion B of its motion, the train would have the smallest speed because the slope of the position time graph is the lowest for portion B.

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

As given in the problem we have to find out for which portion of the motion the train would have the smallest speed,

As we know that speed is given by the slope of the position-time graph.

For portion C the slope of the given position-time graph is highest therefore the speed of the train would be largest for portion C.

For portion B the slope of the given position-time graph is lowest therefore the speed of the train would be lowest for portion B.

nonmetal.
O An attraction between a positive charge and a negative charge is created.
The bonds can shift because valence electrons are held loosely and move freely.

Answers

Answer:

The bonds can shift because valence electrons are held loosely and move freely.

Explanation:

The metallic bonds are responsible for many properties of metals, such as conductivity, the reason is, the bonds can shift because valence electrons are held loosely and move freely.

Metallic bond is the force that binds two metallic substances together.

The valence electron in this type of bond are always in constant motion, causing the electron to move from one neighboring atom to another.

This free electron character of the valence electron of the metallic bond is responsible for the high electrical conductivity of metals.

The valence electrons are always free to move when an electrical field is applied in the metal.

Thus, the metallic bonds are responsible for many properties of metals, such as conductivity, the reason is, the bonds can shift because valence electrons are held loosely and move freely.
