What are some differences you can spot in a periodic table?

Serggg [28]

"The position of each element in the table gives important information about its structure, properties, and behavior in chemical reactions. Specifically, an element's position in the periodic table helps you figure out its electron configuration, how the electrons are organized around the nucleus."

An object of mass 8kg moved around the circle of radius 4m. with a constant speed of 15m/s.

Marianna [84]

Answer:

a. Angular velocity = 0.267rad/s.

b. Centripetal acceleration = 56.25m/s.

Explanation:

Given the following data;

Mass, m = 8kg

Radius, r = 4m

Constant speed, V = 15m/s

a. To find the angular velocity

Angular velocity = radius/speed

Substituting into the equation, we have;

Angular velocity = 4/15

Angular velocity = 0.267rad/s

b. To find the acceleration;

Centripetal acceleration = V²/r

Substituting into the equation, we have;

Centripetal acceleration = 15²/4

Centripetal acceleration = 225/4

Centripetal acceleration = 56.25m/s.

In a completely frictionless Newton's Cradle toy, the change in speed of the balls coming in and those going out is zero. This i

BlackZzzverrR [31]

Answer:

False. The net force is Zero

Explanation:

To answer this question we propose the solution of the problem.

We have a toy where balls come in and out after crashes between them, this toy forms our system, so all the balls are parts of the system, when the balls collide with each other according to Newton's third law force and action and reaction, so it has the same magnitude, but opposite direction, this is each is applied to some of the objects.

In conclusion of the previous one for the system the net force is Zero, all are internal. Therefore, the only thing that happens is a redistribution of speeds according to the conservation of the moment.

Let's review the answer.

False. The net force is Zero
