Physics

valentinak56 [21]3 years ago
4 0
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.

Which term best describes how fast and in what direction an object is moving at a particular moment? Question 2 options: acceler
kompoz [17]

Answer:

Instantaneous velocity

Explanation:

Acceleration = rate of change of velocity

Average velocity = total displacement divided by total time taken

Position = It shows the location of the object

Instantaneous velocity = It is the velocity of an object at a particular instant.

The term that describes how fast and in what direction an object is moving at a particular moment is "instantaneous velocity". It is basically equal to the derivative of position wrt time.

What would happen when there is a collision between two objects having unequal masses
Mashcka [7]

Answer:

Newton's Laws Applied to Collisions. Newton's third law of motion is naturally applied to collisions between two objects. ... Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. what is the lizard average acceleration
VLD [36.1K]

Acceleration = (change in speed) / (time for the change)

change in speed = (ending speed) - (starting speed)

change in speed = (10 m/s) - (2 m/s)  =  8 m/s

Acceleration = (8 m/s) / (4 sec)

Acceleration = (8/4) (m/s²)

<em>Acceleration = 2 m/s²</em>
