In an electron cloud, an electron farther east away from the nucleus has?

8 0

An electron that is far away from the nucleus have higher energy than an electron near the nucleus. Nucleus are positively charged and those electrons near it get attracted; those electrons gain kinetic energy hence reducing their internal energy. The electrons far from nucleus have low kinetic energy hence more internal energy.

Which statement about motor development is true?

BigorU [14]

Answer:

(a) Motor skills are interrelated.

Explanation:

As per the question,

<u>Motor development:</u>

It is defined as the development of movement abilities such as the development of a child's bones, muscles and ability to move around and manipulate his or her environment.

Importance of a Motor Development Model are:

(1) Helps us make sense of developmental changes

(2) Provides a framework for observing the change

(3) Helps us include important factors of motor behavior in our observations.

Hence, Only option (a) is correct.

The circuit below contains an ideal battery, four identical light bulbs, and a switch. The switch is initially open.

Dafna1 [17]

The question is incomplete! circuit figure is attached below and answer and explanation is provided below.

Answer:

Bulb_A = Bulb_B = Bulb_D and Bulb_C = 0.

Explanation:

What happens when switch is open?

When the switch is open Bulb_C is open circuited meaning that there is no way for the current to flow through it. This path offers infinite resistance to the current therefore, current will try to take a least resistance path that is through Bulb_B.

So eventually, when the switch is open the circuit becomes a simple series circuit with path From battery to Bulb_A to Bulb_B to Bulb_D to battery with Bulb_C = 0.

What happens in a series circuit?

We know that in a series circuit, there is only one path for the current to flow therefore, same current will flow through all the series Bulbs and their brightness will be same. Bulb_A = Bulb_B = Bulb_D

Brightness in a series circuit:

We also know know that in a series circuit, resistance gets summed up and voltage across each Bulb gets shared which results in less power dissipation that's why Bulbs connected in series appear dimmer as compared to when they are connected in parallel.

A ball is thrown upwards and returns to the same location. Compared with its initial speed its speed when it returns is about___

Strike441 [17]

Answer:

Explanation:

Let the ball is thrown upwards with speed u and reaches upto height h.

Use III equation of motion

$v^{2}=u^{2}-2gh$

here, final velocity v = 0

So, $u = \sqrt{2gh}$

Now as the ball reaches the maximum height, it starts falling freely. Let it strkes with the ground with velocity v'.

$v'^{2}=u^{2}-2gh$

here, u = 0

So, $v' = \sqrt{2gh}$

It means the velocity is same as the velocity of projection.

Pierce conducts an experiment in which waves collide in a way that the energy increases. What has occurred? refraction reflectio

Vitek1552 [10]

Answer:

constructive interference.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m.

In this scenario, an experiment is conducted by Pierce in which waves collide in a way that the energy increases. Thus, this is an example of constructive interference i.e constructive interference has occurred.

An interference occurs when two pair of waves such as sound and light waves pass through each other i.e crossing each other's path while traveling through the same medium or space.
